The perception of success of such interactions is dependent on employees &quot;who can adjust themselves to the personality of the guest&quot;. Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback.\r\nA <span style=\"font-weight: bold;\">customer support</span> is a range of customer services to assist customers in making cost effective and correct use of a product. It includes assistance in planning, installation, training, trouble shooting, maintenance, upgrading, and disposal of a product. These services even may be done at customer's side where he/she uses the product or service. In this case it is called &quot;at home customer services&quot; or &quot;at home customer support.&quot;\r\nRegarding technology, products such as mobile phones, televisions, computers, software products or other electronic or mechanical goods, it is termed technical support. \r\nCustomer service may be provided by a person (e.g., sales and service representative), or by automated means, such as kiosks, Internet sites, and apps.\r\n<span style=\"font-weight: bold;\">CRM </span>(Customer Relationship Management) is an approach to manage a company's interaction with current and potential customers. It uses data analysis about customers' history with a company to improve business relationships with customers, specifically focusing on customer retention and ultimately driving sales growth.\r\nOne important aspect of the CRM approach is the systems of CRM that compile data from a range of different communication channels, including a company's website, telephone, email, live chat, marketing materials and more recently, social media. Through the CRM approach and the systems used to facilitate it, businesses learn more about their target audiences and how to best cater to their needs.\r\nCRM helps users focus on their organization’s relationships with individual people including customers, service users, colleagues, or suppliers.\r\nWhen people talk about customer relationship management system, they might mean any of three things: \r\n<ul><li><span style=\"font-weight: bold;\">CRM as Technology</span>: This is a technology product, often in the cloud, that teams use to record, report and analyse interactions between the company and users. This is also called a CRM system or solution.</li><li><span style=\"font-weight: bold;\">CRM as a Strategy</span>: This is a business’ philosophy about how relationships with customers and potential customers should be managed.&nbsp; </li><li><span style=\"font-weight: bold;\">CRM as a Process</span>: Think of this as a system a business adopts to nurture and manage those relationships.</li></ul>\r\n<br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Why is CRM important?</span></h1>\r\nCRM management system enables a business to deepen its relationships with customers, service users, colleagues, partners and suppliers.\r\nForging good relationships and keeping track of prospects and customers is crucial for customer acquisition and retention, which is at the heart of a CRM’s function. You can see everything in one place — a simple, customizable dashboard that can tell you a customer’s previous history with you, the status of their orders, any outstanding customer service issues, and more.\r\nGartner predicts that by 2021, CRM technology will be the single largest revenue area of spending in enterprise software. If your business is going to last, you know that you need a strategy for the future. For forward-thinking businesses, CRM is the framework for that strategy.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the benefits of CRM?</span></h1>\r\nBy collecting and organising data about customer interactions, making it accessible and actionable for all, and facilitating analysis of that data, CRM offers many benefits and advantages.<br />The benefits and advantages of CRM include:\r\n<ul><li>Enhanced contact management</li><li>Cross-team collaboration</li><li>Heightened productivity</li><li>Empowered sales management</li><li>Accurate sales forecasting</li><li>Reliable reporting</li><li>Improved sales metrics</li><li>Increased customer satisfaction and retention</li><li>Boosted marketing ROI</li><li>Enriched products and services</li></ul>\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the key features of most popular CRM software programs?</span></h1>\r\nWhile many CRM solutions differ in their specific value propositions — depending on your business size, priority function, or industry type — they usually share some core features. These, in fact, are the foundation of any top CRM software, without which you might end up using an inferior app or an over-rated address book. So, let’s discuss the key features you need to look for when figuring out the best CRM software for your business.\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Contact management</span>. The best CRM solutions aren’t just an address book that only organizes contact details. It manages customer data in a centralized place and gives you a 360-degree view of your customers. You should be able to organize customers’ personal information, demographics, interactions, and transactions in ways that are meaningful to your goals or processes. Moreover, a good contact management feature lets you personalize your outreach campaign. By collecting personal, social, and purchase data, it will help you to segment target audience groups in different ways.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Reporting and dashboards</span>. These features of customer relationship management allow you to use analytics to interpret customer data. Reporting is very useful if you want to consolidate disparate data and churn out insights in different visualizations. This lets you make better decisions or proactively deal with market trends and customer behavioral patterns. The more visual widgets a CRM software has, the better you can present reports. Furthermore, a best customer relationship management software will generate real-time data, making reporting more accurate and timely. Reporting also keeps you tab on sales opportunities like upsell, resell, and cross-sell, especially when integrated with e-commerce platforms.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Lead management</span>. These features let you manage leads all the way to win-loss stage. They pave a clear path to conversion, so you can quickly assess how the business is performing. One of the main three legs that comprises the best client relationship management software (the other two being contact management and reporting), lead management unburdens the sales team from follow-ups, tracking, and repetitive tasks.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Deals and tasks</span>. Deals and tasks are closely associated with leads. Deals are leads at the negotiation stage, so it’s critical to keep a close eye on their associated tasks for a higher chance of conversion.<br />CRM software tools should also let you track both deals and tasks in their respective windows or across the sales stages. Whether you’re viewing a contact or analyzing the sales pipeline, you should be able to immediately check the deal’s tasks and details. Deals and tasks should also have user permissions to protect leaks of sensitive data. Similarly, alerts are critical to tasks so deadlines are met. Notifications are usually sent via email or prominently displayed on the user’s dashboard.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Campaign management</span>. Solid CRM software will integrate this feature to enable marketing processes from outreach concept to A/B testing to deployment and to post analysis. This will allow you to sort campaigns to target segments in your contacts and define deployment strategies. You will also be able to define metrics for various channels, then plow back the insights generated by post-campaign analytics into planning more campaigns.<br />Recurring outreach efforts can also be automated. For instance, you can set to instantly appropriate content to contacts based on their interest or send tiered autoresponders based on campaign feedback.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Email management</span>. By integrating with popular email clients like Gmail and Outlook, CRM solutions can capture email messages and sort important details that can be saved in contacts or synced with leads. They can also track activities like opened emails, forwarded emails, clicked links, and downloaded files. Emails can also be qualified for prospecting.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Social media management. </span>Popular CRM systems feature an integrated social media management where you can view different social media pages from the CRM’s interface. This is a convenient way to post, reply on, and manage all your pages. Likewise, this feature gives you a better perspective on how customers are interacting with your brand. A glean of their likes and dislikes, interests, shares, and public conversations helps you to assess customer biases and preferences. Customers are also increasingly using social media to contact companies; hence, a good CRM should alert you for brand mentions.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Mobile access</span>. With more users accessing apps via mobile devices, many vendors have been prioritizing mobile-first platforms. Emergence Capital Partners study found over 300 mobile-first apps so far and CRM is definitely one their targets. Many CRM solutions have both Android and iOS apps. Mobile access works in two ways to be highly appreciated: accessing data and inputting data while on location. Field sales with the latest sales information on hand may be able to interest prospects better. Conversely, sales reps can quickly update deals across the pipeline even as they come off a client meeting.</li></ul>\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/CRM_-_Customer_Relationship_Management.png","alias":"crm-customer-relationship-management"},"75":{"id":75,"title":"ERP - Enterprise Resource Planning","description":"<span style=\"font-weight: bold; \">Enterprise resource planning (ERP)</span> is the integrated management of main business processes, often in real-time and mediated by software and technology.\r\nEnterprise resource planning system is usually referred to as a category of business management software — typically a suite of integrated applications—that an organization can use to collect, store, manage, and interpret data from these many business activities.\r\nERP provides an integrated and continuously updated view of core business processes using common databases maintained by a database management system. \r\nEnterprise resource planning solutions track business resources— cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across various departments (manufacturing, purchasing, sales, accounting, etc.) that provide the data. \r\n<p class=\"align-left\">ERP facilitates information flow between all business functions and manages connections to outside stakeholders.</p>\r\n<p class=\"align-left\">You can think of an enterprise resource planning system as the glue that binds together the different computer systems for a large organization. Without an ERP application, each department would have its own system optimized for that division's particular tasks. With ERP software, each department still has its own system, but all of the systems can be accessed through one application with one interface.</p>\r\n<p class=\"align-left\">ERP applications also allows the different departments to communicate and share information more easily with the rest of the company. It collects information about the activity and state of different divisions, making this information available to other parts, where it can be used productively.</p>\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">ERP systems typically include the following characteristics:</span></p>\r\n<ul><li>An integrated system</li><li>Operates in (or near) real time</li><li>A common database that supports all the applications</li><li>A consistent look and feel across modules</li><li>Installation of the system with elaborate application/data integration by the Information Technology (IT) department, provided the implementation is not done in small steps</li><li>Deployment options include: on-premises, cloud hosted, or SaaS</li></ul>\r\n<p class=\"align-left\">Enterprise resource planning programs have traditionally been used by the big players in the market that have thousands of employees spread out over the world. However, software developers are now marketing business ERP solutions to small- and medium-sized companies. </p>\r\n<p class=\"align-left\">There are different types of ERP software ranging from industry-specific ERP solutions to web-based, or cloud ERP software; to small business ERP.<br />The type of ERP system that will work best for your business depends on the size of your organization and the functions of the ERP solution that can best support your business requirements.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Industry Specific ERP.</span> ERP systems for large corporations are often built from the ground up to suit the organization's specific and unique needs. For a small business like yours, an off-the-shelf model will work fine. Most are grouped into three categories to service manufacturing, finance or logistics based companies.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Web-Based ERP system.</span> ERP software services tend to be complex, requiring high-end computers to run them. However, instead of purchasing the software to run on your computer in your office, many suppliers offer Software as a Service, or SaaS. In this case, you pay a subscription to access the software and your data over the internet. Because the program is running on a remote server, you are free to access it from anywhere you have an Internet connection.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">ERP software for small business.</span> Although ERP systems can cover everything from supply chain management to accounting solutions as well as customer relations management, your business may not need to automate all these functions. Therefore, software developers offer scaled-down models at a lower, more cost-effective price. For instance, your operation may work fine with a system that offers sales and order management, but leaves out the module for warehouse management.<br /><br /><br /><br /><br /></p>","materialsDescription":"<h1 class=\"align-center\"> <span style=\"font-weight: normal;\">What does an ERP do?</span></h1>\r\nThe purpose of an ERP management system is to improve efficiency (and thereby profitability) through improving how company resources are spent, whether those resources be time, money, staff or something else.<br />If you can reduce how many resources are being used, without sacrificing quality/performance, then you can grow your business more efficiently and appropriately.\r\nERP software combines a number of different reports and metrics across various departments into the same environment. This makes it easier to get a full view of what’s going on and how resources are being spent.<br />From this vantage point of the business, you can discover key insights into how processes might be improved or resources better spent to generate higher growth. \r\nWithout an ERP system and proper planning of how resources should be spent to maximize growth and the bottom line, it is much easier to invest resources in tactics that underperform.\r\nConversely, a great ERP software platform allows a business to allocate resources away from underperforming tactics and into those that are generating good returns.\r\n<p class=\"align-left\">An ERP system also makes it faster to find the information or report you’re after because everything is in the same place. You don’t have to search through spreadsheets or look through different business applications to find that kernel of data you need; it’s all available and accessible right from the ERP interface.</p>\r\n<header><h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the different features of ERP software?</span></h1>\r\n<p class=\"align-center\"></p></header>\r\nERP software can differ depending on the package you purchase and the provider. That being said, there are some key features that you should look for when researching ERP software providers. Your software should, at the bare minimum, offer the following modules:\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Accounting:</span> Manage all of your financial reports in the same interface, such as purchase orders, expenses, sales reports, payroll, etc. This makes it easier to monitor your cash flow and revenue and determines how money might be better spent or how you can reduce your burn rate.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Inventory and warehousing</span>: If your business has inventory or warehouse processes, your ERP business software needs to be able to integrate those operations to better track and manage goods. This makes it easier to see how much inventory is available, what inventory is going out for delivery, what inventory is coming in from which vendors and more. Carefully monitoring and tracking these processes helps protect a business from running out of stock, mismanaging a delivery and other potential issues.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">eCommerce and web</span>: It’s essential for a business to be able to see the eCommerce side of their business separate from physical, retail sales. After all, the tactics you leverage to encourage online sales are different than the ones you use for your physical stores. An excellent ERP system will enhance your existing web offerings to include better purchase options for customers to choose from.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Human resources</span>: As much as a business strives to keep customers happy and retained, it is equally important that your employees remain happy as well. The HR module of your ERP system contains all of the employee management processes, including payroll expenses, recruitment, performance evaluations, attendance, scheduling and more. It’s a one-stop module for all employee management and communication efforts.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">CRM and marketing</span>: Your brand-customer relationships are ultimately going to drive repeat business. It’s important to know how effectively your marketing tactics are working at engaging and re-engaging customers, whether those tactics are email marketing campaigns, social media offers, surveys, follow-up phone calls and others. The CRM module will better express what’s working and what isn’t and how marketing is translating into added revenue.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Project management:</span> The last should-have feature of your ERP software product is a project management tool, which allows you to communicate productively across your organization to plan and execute projects internally. This helps ensure company cohesion by getting every involved stakeholder or employee on the same page and in-the-know as to the most current business objectives and goals.</li></ul>\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Benefits of ERP software and why to build it</span></h1>\r\n<p class=\"align-left\">In today’s business environments, it’s hard to move on without an ERP system. Among the main benefits of ERP implementation is automatization of manual tasks staff spends hours on and thus improves the overall business performance. So the staff can focus on more important initiatives. At the same time, you can collect real-time data for improving performance management and making data-driven decisions.<br />ERP&nbsp; planning software comes handy in lots of areas due to its in-built modules and flexibility. Here are a few advantages of ERP software tools:</p>\r\n<p class=\"align-left\"><br />1. <span style=\"font-weight: bold;\">Reduce operating cost</span>. The company starts gaining profit as soon as the ERP system is implemented. Prepare to face the reduction of marketing expenses, inventory maintenance, production cost and so on. Also, if you’re aimed at combining all business processes within a unified system, ERP is the right choice. By using the software, it’s easy to improve cross-department cooperation and increase staff’s efficiency.</p>\r\n<p class=\"align-left\">2.<span style=\"font-weight: bold;\"> Instant data access.</span> With ERP systems, employees soon forget about hours spent on collecting necessary details. Instead, they can be accessed in just a few minutes. Works great for busy executives and department managers that need to access data quickly.</p>\r\n<p class=\"align-left\">3. <span style=\"font-weight: bold;\">Defined planning process.</span> It’s easy to understand the business objectives, targets and aims when you have a full list of business needs, outcomes, and assets all in one place.</p>\r\n<p class=\"align-left\">Sure, ERP systems also have some disadvantages. The most common issue is the price. It’s almost impossible for small companies to develop an ERP suite for their own needs, only middle and large-sized corporations can afford it.<br /><br /><br /><br /><br /></p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/ERP_-_Enterprise_Resource_Planning.png","alias":"erp-enterprise-resource-planning"},"182":{"id":182,"title":"CMS - Content management system","description":"A content management system (CMS) manages the creation and modification of digital content. It typically supports multiple users in a collaborative environment.\r\nCMS features vary widely. Most CMSs include Web-based publishing, format management, history editing and version control, indexing, search and retrieval. By their nature, content management systems support the separation of content and presentation.\r\nContent management software solutions are typically used for enterprise content management systems (ECM) and web site content management systems (WCM). An ECM facilitates collaboration in the workplace by integrating document management, digital asset management and records retention functionalities, and providing end users with role-based access to the organization's digital assets. A WCM facilitates collaborative authoring for websites. ECM software often includes a WCM publishing functionality, but ECM webpages typically remain behind the organization's firewall.\r\nBoth enterprise content management and web content management systems have two components: a content management application (CMA) and a content delivery application (CDA). The CMA is a graphical user interface (GUI) that allows the user to control the design, creation, modification and removal of content from a website without needing to know anything about HTML. The CDA component provides the back-end services that support management and delivery of the content once it has been created in the CMA.\r\nDigital asset management systems are another type of CMS. They manage content with a clearly defined author or ownership, such as documents, movies, pictures, phone numbers, and scientific data. Companies also use CMSs to store, control, revise, and publish documentation.\r\nBased on market share statistics, the most popular CMS is WordPress, used by more than 28% of all websites on the Internet, and by 59% of all websites using a known content management system, followed by Joomla and Drupal.\r\n<span style=\"font-weight: bold;\">Content management systems typically provide the following features:</span>\r\n<ul><li>Search engine optimization</li><li>Integrated and online documentation</li><li>Modularity and extensibility</li><li>User and group functionality</li><li>Templating support for changing designs</li><li>Installation and upgrade wizards</li><li>Integrated audit logs</li><li>Compliance with various accessibility frameworks and standards, such as WAI-ARIA</li><li>Reduced need to code from scratch</li><li>Unified user experience</li><li>Version control</li><li>Edit permission management</li></ul>","materialsDescription":"<h1 class=\"align-center\"> <span style=\"font-weight: normal;\">What is a CMS?</span></h1>\r\nAnswer: CMS is an acronym for &quot;Content Management System&quot;.

Content management solutions help webmasters manage the many different resources, content types and various data that make up modern web sites.</p>\r\n<p class=\"align-left\">At a minimum, modern websites make use of HTML, CSS, JavaScript and images (jpeg, gif, png, etc) to create web content for visitors to read. At the core of every CMS is the ability to organize these resources and generate valid content that can be read by web browsers. </p>\r\n<p class=\"align-left\">More advanced websites have interactive components (comment sections, forums, e-commerce...) that requires server software to validate and save user submitted content.<br />All of the top CMS platforms have features built-in or available for download as addons for all of these features.</p>\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the main types of CMS?</span></h1>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Simple CMS.</span> This system is used to create simple websites that contain several pages using simple control systems. Simple content management systems consist of several modules that are set one time. These CMSs are free and are available on the internet. Among their disadvantages are the inability to change settings, low transmission capacity, inability to create pages dynamically and the inability of ato delegateion of administrator’s credentials to others.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\">&nbsp;</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Template CMS.</span> It consists of modules as well, but its structure is more complex if compared to a simple CMS. Template CMS has high transmission capacity, around 50,000 inquiries. Also, it has the support of dynamic pages and the ability to delegate the administrator’s credentials. Many template systems are used to create website content because they are easy to use.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\">&nbsp;</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Professional CMS</span>. This type of CMS has a higher level of complexity. You may change the structure of internet resources. Additional modules can be attached to these systems. These systems are used to create information portals or massive projects. As a rule, these CMSs are a paid resource.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\">&nbsp;</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Universal CMS</span>. Universal systems have wide functionality and ample opportunities to develope websites of any complexity. They support the functions of changing the structure, creating dynamic pages, modification of settings and credential distribution. Universal CMS is quite expensive. These CMSs are used for work with large portals and web-projects that require high functionality and dynamics.<br /><br /><br /><br /><br /><br /></p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/CMS_-_content_management_system.png","alias":"cms-content-management-system"},"565":{"id":565,"title":"Design","description":" Design is the activity of designing the aesthetic properties of industrial products (“artistic design”), as well as the result of this activity (for example, in such phrases as “car design”).\r\nIt is believed that in a broader sense, the design is not only intended for artistic design, but should also be involved in solving broader social and technical problems of the functioning of production, consumption, and the existence of people in the objective environment, by rational construction of its visual and functional properties.\r\nThe theoretical basis of design is technical aesthetics.\r\nThe term “industrial design” was approved by the decision of the first General Assembly of the ICSID (International Council of Societies of Industrial Design, International Council of Industrial Design Organizations) in 1959; The term “design” is a professional abbreviation of the term “industrial design”.\r\nDesigner - artist-designer, a person engaged in artistic and technical activities in various industries (including an architect, designer, illustrator, poster and other advertising graphics designer, web designer).\r\nThe word &quot;design&quot; English-language literature of the beginning of the XXI century, and understands the style, and the project, and design, and actually &quot;design&quot; - a professional activity, along with architecture or engineering design.","materialsDescription":" <span style=\"font-weight: bold;\">Design object</span>\r\nThe object of design can be almost any new technical industrial product (set, ensemble, complex, system) in any sphere of life activity of people, where human communication is socially and culturally conditioned.\r\n<span style=\"font-weight: bold;\">The main categories of the design object are:</span>\r\nThe image is an ideal representation of the object, an artistic-figurative model created by the designer’s imagination.\r\n<ul><li> Function - the work that the product must perform, as well as the semantic, sign and value role of the thing.</li><li>Morphology - the structure, the structure of the shape of the product, organized in accordance with its function, material and method of manufacture, embodying the designer's intent.</li><li>Technological form - morphology, embodied in the method of industrial production of the thing-object of the design-design as a result of artistic understanding of technology.</li><li>Aesthetic value is a special value of an object revealed by a person in a situation of aesthetic perception, emotional, sensory experience and assessment of the degree of conformity of an object to the aesthetic ideal of a subject.</li></ul>\r\n<span style=\"font-weight: bold;\">Techniques for finding a design solution:</span>\r\n<ul><li>Exhibition modeling</li><li>Museum situational modeling</li><li>Reincarnation or borrowing position</li><li>Person projection into the projected object</li><li>Scenario modeling</li><li>Game Situational Modeling</li><li>Mathematical and physical modeling of the dynamics of an object in the environment</li><li>Generative Design</li></ul>\r\n<span style=\"font-weight: bold;\">Varieties of design:</span>\r\n<ul><li>Animation design</li><li>Architectural design</li><li>Web design</li><li>Game design</li><li>Graphic design</li><li>Urban design</li><li>Interior Design</li><li>Clothing design</li><li>Ceremony Design</li><li>Sound design</li><li>Information design</li><li>Book design</li><li>Landscape Design</li><li>Parametric design</li><li>Print design</li><li>Interaction design</li><li>Software design</li><li>Industrial Design</li><li>Light design</li><li>Transport design</li><li>Futurodesign</li><li>Ecodesign</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Design.png","alias":"design"},"567":{"id":567,"title":"Graphics Design","description":" Graphic design is the process of visual communication and problem-solving through the use of typography, photography, and illustration. The field is considered a subset of visual communication and communication design, but sometimes the term &quot;graphic design&quot; is used synonymously. Graphic designers create and combine symbols, images and text to form visual representations of ideas and messages. They use typography, visual arts, and page layout techniques to create visual compositions. Common uses of graphic design include corporate design (logos and branding), editorial design (magazines, newspapers and books), wayfinding or environmental design, advertising, web design, communication design, product packaging, and signage.\r\nGraphic design is applied to everything visual, from road signs to technical schematics, from interoffice memorandums to reference manuals.\r\nDesign can aid in selling a product or idea. It is applied to products and elements of company identity such as logos, colors, packaging and text as part of branding (see also advertising). Branding has become increasingly more important in the range of services offered by graphic designers. Graphic designers often form part of a branding team.\r\nGraphic design is applied in the entertainment industry in decoration, scenery and visual story telling. Other examples of design for entertainment purposes include novels, vinyl album covers, comic books, DVD covers, opening credits and closing credits in filmmaking, and programs and props on stage. This could also include artwork used for T-shirts and other items screenprinted for sale.\r\nFrom scientific journals to news reporting, the presentation of opinion and facts is often improved with graphics and thoughtful compositions of visual information - known as information design. Newspapers, magazines, blogs, television and film documentaries may use graphic design. With the advent of the web, information designers with experience in interactive tools are increasingly used to illustrate the background to news stories. Information design can include data visualization, which involves using programs to interpret and form data into a visually compelling presentation, and can be tied in with information graphics.","materialsDescription":"<span style=\"font-weight: bold;\">What is graphic design and what does it include?</span>\r\nGraphic design is a design process that combines text and graphics in a way that is intended to communicate a specific message.\r\n<span style=\"font-weight: bold;\">Where is graphic design used?</span>\r\nYou will find graphic design in company logos, printed materials like brochures, posters, signs, greeting cards, postcards, business cards, billboards and ads. Advances in technology have brought us the digital environment complete with websites, online ads, virtual brochures and presentations, and so very much more.\r\n<span style=\"font-weight: bold;\">What do graphic designers use to create these designs?</span>\r\nGraphic designers can use hand-illustrated designs as well as computer-aided designs thanks to a wide range of software with nearly endless digital design tools. The availability of software like Adobe Illustrator and Photoshop have become staples of the graphic designer.\r\n<span style=\"font-weight: bold;\">What can a graphic designer do that I can’t do?</span>\r\nA graphic designer does more than just put their creative skills to work. Though most graphic designers are intuitively creative already, they have generally spent time studying numerous design principles. It’s vital to understand how to use design elements to transmit the required messages and values as well as evoke a certain feeling in the viewer. As a visual communicator, they leverage these design elements and use concepts such as color, typography, space, balance, form and lines to create their visual message.\r\nSome graphic designers are also able to understand the more technical aspects of the design required to create digital assets for a company. For example, a web designer is often able to create wireframes, workflows, and sitemaps and understand how to develop easy navigation for the user experience.\r\n<span style=\"font-weight: bold;\">What else does a graphic designer accomplish as part of the work they produce for a client?</span>\r\nBesides turning their client’s vision, brand image and value proposition into a graphic display, a designer will undertake many specialty tasks as part of a graphic design project. The specialty tasks include collaborating on the concept (usually with a team), attending meetings about the project, paying attention to what customers are clicking on, doing presentations that explain the various potential designs, revising designs, and preparing asset files for others on the team and for client use.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Graphics_Design.png","alias":"graphics-design"},"569":{"id":569,"title":"Website Design","description":" Web design is the process of creating websites. It encompasses several different aspects, including webpage layout, content production, and graphic design. While the terms web design and web development are often used interchangeably, web design is technically a subset of the broader category of web development.\r\nWebsites are created using a markup language called HTML. Web designers build webpages using HTML tags that define the content and metadata of each page. The layout and appearance of the elements within a webpage are typically defined using CSS, or cascading style sheets. Therefore, most websites include a combination of HTML and CSS that defines how each page will appear in a browser.\r\nSome web designers prefer to hand code pages (typing HTML and CSS from scratch), while others use a &quot;WYSIWYG&quot; editor like Adobe Dreamweaver. This type of editor provides a visual interface for designing the webpage layout and the software automatically generates the corresponding HTML and CSS code. Another popular way to design websites is with a content management system like WordPress or Joomla. These services provide different website templates that can be used as a starting point for a new website. Webmasters can then add content and customize the layout using a web-based interface.\r\nWhile HTML and CSS are used to design the look and feel of a website, images must be created separately. Therefore, graphic design may overlap with web design, since graphic designers often create images for use on the Web. Some graphics programs like Adobe Photoshop even include a &quot;Save for Web…&quot; option that provides an easy way to export images in a format optimized for web publishing.","materialsDescription":" <span style=\"font-weight: bold;\">Why is Web Design Important?</span>\r\nIt can be difficult to understand why most businesses are willing to pay top dollar for web design work.

Today, the most important aspect of an online business presence in web design.\r\nThis means that businesses should always try to find the best web styles that work for their businesses. Although there are several people who can create websites, it takes a skilled person to design a website that looks polished and functional. Here are some more reasons why web design is important to good business.\r\n<span style=\"font-weight: bold;\">A Good Site Increases Customer Conversion</span>\r\nWhen a business has a well-designed website, it becomes easier to get more customer conversions.

Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.\r\nSoftware can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open-source software), or for personal use (e.g. a scientist may write software to automate a mundane task). Embedded software development, that is, the development of embedded software, such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself and is often developed separately.\r\nThe need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.\r\nThere are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development.","materialsDescription":" <span style=\"font-weight: bold; \">What is software development?</span>\r\nSoftware itself is the set of instructions or programs that tell a computer what to do. It is independent of hardware and makes computers programmable. There are three basic types:\r\n<span style=\"font-weight: bold; \">System software</span> to provide core functions such as operating systems, disk management, utilities, hardware management, and other operational necessities.\r\n<span style=\"font-weight: bold; \">Programming software</span> to give programmers tools such as text editors, compilers, linkers, debuggers and other tools to create code.\r\n<span style=\"font-weight: bold; \">Application software</span> (applications or apps) to help users perform tasks. Office productivity suites, data management software, media players and security programs are examples. Applications also refer to web and mobile applications like those used to shop on Amazon.com, socialize with Facebook or post pictures to Instagram.\r\nA possible fourth type is <span style=\"font-weight: bold; \">embedded software.</span> Embedded systems software is used to control machines and devices not typically considered computers — telecommunications networks, cars, industrial robots and more. These devices, and their software, can be connected as part of the Internet of Things (IoT).\r\nSoftware development is primarily conducted by programmers, software engineers, and software developers. These roles interact and overlap, and the dynamics between them vary greatly across development departments and communities.\r\n<span style=\"font-weight: bold; \">Programmers, or coders,</span> write source code to program computers for specific tasks like merging databases, processing online orders, routing communications, conducting searches or displaying text and graphics. Programmers typically interpret instructions from software developers and engineers and use programming languages like C++ or Java to carry them out.\r\n<span style=\"font-weight: bold; \">Software engineers</span> apply engineering principles to build software and systems to solve problems. They use modeling language and other tools to devise solutions that can often be applied to problems in a general way, as opposed to merely solving for a specific instance or client. Software engineering solutions adhere to the scientific method and must work in the real world, as with bridges or elevators.\r\n<span style=\"font-weight: bold; \">Software developers</span> have a less formal role than engineers and can be closely involved with specific project areas — including writing code. At the same time, they drive the overall software development lifecycle — including working across functional teams to transform requirements into features, managing development teams and processes, and conducting software testing and maintenance.\r\nThe work of software development isn’t confined to coders or development teams. Professionals such as scientists, device fabricators, and hardware makers also create software code even though they are not primarily software developers. Nor is it confined to traditional information technology industries such as software or semiconductor businesses. In fact, according to the Brookings Institute, those businesses “account for less than half of the companies performing software development.”\r\nAn important distinction is custom software development as opposed to commercial software development. Custom software development is the process of designing, creating, deploying and maintaining software for a specific set of users, functions or organizations. In contrast, commercial off-the-shelf software (COTS) is designed for a broad set of requirements, allowing it to be packaged and commercially marketed and distributed.\r\n<span style=\"font-weight: bold;\">Steps in the software development process</span>\r\nDeveloping software typically involves the following steps:\r\n<ul><li><span style=\"font-weight: bold;\">Selecting a methodology</span> to establish a framework in which the steps of software development are applied. It describes an overall work process or roadmap for the project. Methodologies can include Agile development, DevOps, Rapid Application Development (RAD), Scaled Agile Framework (SAFe), Waterfall and others.</li><li><span style=\"font-weight: bold;\">Gathering requirements</span> to understand and document what is required by users and other stakeholders.</li><li><span style=\"font-weight: bold;\">Choosing or building architecture</span> as the underlying structure within which the software will operate.</li><li><span style=\"font-weight: bold;\">Developing a design</span> around solutions to the problems presented by requirements, often involving process models and storyboards.</li><li><span style=\"font-weight: bold;\">Constructing code</span> in the appropriate programming language.

Establish quality assurance priorities and release criteria to address and track defects.</li><li><span style=\"font-weight: bold;\">Deploying</span> the software for use and responding to and resolving user problems.</li><li><span style=\"font-weight: bold;\">Migrating data</span> to the new or updated software from existing applications or data sources if necessary.</li><li><span style=\"font-weight: bold;\">Managing and measuring the project</span> to maintain quality and delivery over the application lifecycle, and to evaluate the development process with models such as the Capability Maturity Model (CMM).</li></ul>\r\nThe steps of the software development process fit into application lifecycle management.\r\n<ul><li>Requirements analysis and specification</li><li>Design and development</li><li>Testing</li><li>Deployment</li><li>Maintenance and support</li></ul>\r\nSoftware development process steps can be grouped into the phases of the lifecycle, but the importance of the lifecycle is that it recycles to enable continuous improvement. For example, user issues that surface in the maintenance and support phase can become requirements at the beginning of the next cycle.\r\n<span style=\"font-weight: bold;\">Why is software development important?</span>\r\nSoftware development is important because it helps businesses differentiate themselves and be more competitive. It can improve customer experiences, bring more innovative, feature-rich products to market faster, and make operations more efficient, safe and productive.\r\nSoftware development is also important because it is pervasive.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Development.png","alias":"software-development"},"593":{"id":593,"title":"Mobile Software Development","description":" Mobile app development is the act or process by which a mobile app is developed for mobile devices, such as personal digital assistants, enterprise digital assistants or mobile phones. These applications can be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing (e.g., JavaScript) to provide an &quot;application-like&quot; experience within a Web browser. Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms. Mobile app development has been steadily growing, in revenues and jobs created. A 2013 analyst report estimates there are 529,000 direct app economy jobs within the EU 28 members, 60% of which are mobile app developers.\r\nAs part of the development process, mobile user interface (UI) design is also essential in the creation of mobile apps. Mobile UI considers constraints, contexts, screen, input, and mobility as outlines for design. The user is often the focus of interaction with their device, and the interface entails components of both hardware and software. User input allows for the users to manipulate a system, and device's output allows the system to indicate the effects of the users' manipulation. Mobile UI design constraints include limited attention and form factors, such as a mobile device's screen size for a user's hand(s). Mobile UI contexts signal cues from user activity, such as location and scheduling that can be shown from user interactions within a mobile app. Overall, mobile UI design's goal is mainly for an understandable, user-friendly interface. The UI of mobile apps should: consider users' limited attention, minimize keystrokes, and be task-oriented with a minimum set of functions. This functionality is supported by mobile enterprise application platforms or integrated development environments (IDEs).\r\nMobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems. The mobile back-end facilitates data routing, security, authentication, authorization, working off-line, and service orchestration. This functionality is supported by a mix of middleware components including mobile app server, mobile backend as a service (MBaaS), and service-oriented architecture (SOA) infrastructure. ","materialsDescription":" <span style=\"font-weight: bold;\">What is the native app development?</span>\r\nUnlike websites and web applications, native mobile apps don’t run in the browser. You need to download them from platform-specific app stores such as Apple’s App Store and Google Play. After installation, you can access each app by tapping its respective icon on the screen of your device.\r\nNative app development requires different skills and technologies than mobile website development. You don’t have to worry about browser behavior and compatibility. You can use the native features of mobile OSs to deliver the user experience and implement the functionalities of your app.\r\n<span style=\"font-weight: bold;\">What is the difference between a native mobile app and a hybrid app?</span>\r\nMobile apps have two types: native and hybrid apps. At first glance, both have similar features and design but the underlying technology is different. As the name suggests, hybrid apps are a combination of web apps and native mobile apps. You can build them using web technologies: HTML, CSS, and JavaScript. You can also upload them to app stores and users can install them as native Android or iOS applications.\r\nThe main advantages of hybrid apps are portability and the simplicity of development. You only have to write the code once and your hybrid app will run on different operating systems. You can use hybrid frameworks like Ionic and Apache Cordova to create cross-platform hybrid applications. By contrast, native mobile apps have to be written in platform-specific languages such as Java, Swift, or Objective-C.\r\nNative mobile apps can access the built-in features of smartphones such as the camera and microphone by default. If you have a hybrid app you need to rely on plugins like Cordova plugins to use the native capabilities of the user’s device.\r\nHybrid apps also depend on WebViews to render their user interfaces. WebViews are in-app browsers that allow mobile applications to access and display web content. This is how Android and iOS devices are able to run hybrid apps built with HTML, CSS, and JavaScript as native mobile applications.\r\n<span style=\"font-weight: bold;\">What are the benefits of native mobile app development?</span>\r\nAlthough hybrid apps are easier and cheaper to develop, native mobile apps have many benefits, too.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better performance</span></span>\r\nNative mobile apps directly interact with native APIs without depending on middleware such as plugins and WebViews. As there are fewer dependencies, native mobile apps are faster and more responsive than hybrid apps. This is especially important for performance-centric apps like games and graphic-heavy applications.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Consistent look and feel</span></span>\r\nAs native mobile apps are developed using native SDKs (software development kits), their UIs look consistent with their platform. This ensures a better user experience, as there are no discrepancies between the OS and app design.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Immediate access to new features</span></span>\r\nNative mobile apps can immediately access the latest iOS or Android features. As web technologies can’t directly use native APIs, hybrid apps have to wait until there’s a plugin that supports the new feature.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better compliance with app store guidelines</span></span>\r\nBecause of their architecture, native mobile apps comply better with app store guidelines. In 2017, Apple restricted its submission guidelines. Since then, they have begun to reject apps that rely too much on WebViews, such as Ionic View that allowed developers to test their Ionic applications. As it’s likely that app stores will continue cracking down on hybrid apps, native mobile apps are also a more future-proof investment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Mobile_Software_Development.png","alias":"mobile-software-development"},"595":{"id":595,"title":"iOS Software Development","description":"iOS is Apple’s mobile OS that runs on an iPhone, iPad, iPod Touch hardware.

Xcode is Apple’s IDE (Integrated Development Environment) for both Mac and iOS apps. Xcode is the graphical interface you'll use to write iOS apps. Xcode includes the iOS SDK, tools, compilers, and frameworks you need specifically to design, develop, write code, and debug an app for iOS. For native mobile app development on iOS, Apple suggests using the modern Swift programming language. It is important to note that Xcode only runs on Mac OS X and the only supported way to develop iOS apps.

Google states that &quot;Android apps can be written using Kotlin, Java, and C++ languages&quot; using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some languages/programming tools allow cross-platform app support, i.e. for both Android and iOS. Third party tools, development environments and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, Bank of America etc. eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.\r\nAndroid was created by the Open Handset Alliance, which is led by Google. The early feedback on developing applications for the Android platform was mixed. Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. In December 2007, MergeLab mobile startup founder Adam MacBeth stated, &quot;Functionality is not there, is poorly documented or just doesn't work... It's clearly not ready for prime time.&quot; Despite this, Android-targeted applications began to appear the week after the platform was announced. The first publicly available application was the Snake game.\r\nA preview release of the Android SDK was released on November 12, 2007. On July 15, 2008, the Android Developer Challenge Team accidentally sent an email to all entrants in the Android Developer Challenge announcing that a new release of the SDK was available in a &quot;private&quot; download area. The email was intended for winners of the first round of the Android Developer Challenge. The revelation that Google was supplying new SDK releases to some developers and not others (and keeping this arrangement private) led to widely reported frustration within the Android developer community at the time.\r\nOn August 18, 2008, the Android 0.9 SDK beta was released. This release provided an updated and extended API, improved development tools and an updated design for the home screen. Detailed instructions for upgrading are available to those already working with an earlier release. On September 23, 2008, the Android 1.0 SDK (Release 1) was released. According to the release notes, it included &quot;mainly bug fixes, although some smaller features were added.&quot; It also included several API changes from the 0.9 version. Multiple versions have been released since it was developed.\r\nOn December 5, 2008, Google announced the first Android Dev Phone, a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. It was a modified version of HTC's Dream phone. While developers can use regular consumer devices to test and use their applications, some developers may choose a dedicated unlocked or no-contract device.\r\nAs of July 2013, more than one million applications have been developed for Android, with over 25 billion downloads. A June 2011 research indicated that over 67% of mobile developers used the platform, at the time of publication. Android smartphone shipments are forecast to exceed 1.2 billion units in 2018 with an 85% market share.","materialsDescription":" <span style=\"font-weight: bold;\">Where does Android come from?</span>\r\nIt comes from Google, who actually acquired Android in 2005 (no, Google didn't invent it). The search giant performs regular updates along with an annual major update.\r\nThe operating system is based on the Linux kernel – if you have friends who work in IT, you may have heard of it. This is the GNU / Linux operating system based structure, which is a unix type system (portable operating system, multitasking and multi-user). The Linux kernel is one of the most prominent examples of free software.\r\n<span style=\"font-weight: bold;\">Why does Android look different on each phone?</span>\r\nAndroid doesn't look different on every device, but it does have a number of different versions. Android is open-source, which means that manufacturers are free to customize the software and make it their own.\r\nThe 'purest' version of Android is often referred to as 'stock Android' and it's often preferred by the Android community: it's the original software as Google intended.\r\nOther user interfaces (UI) include Samsung's TouchWiz, Sony's Xperia, and Huawei's Emotion. See what they all look like in our Android UI comparison.\r\n<span style=\"font-weight: bold;\">What are the advantages of Android?</span>\r\nChoice. For example, if you want iOS, you have a choice of iPhone, iPhone or iPhone. If you go for Android there are stacks of great devices to choose from, from cheap and cheerful handsets to really impressive flagships. Those flagships are often cheaper than the equivalent Apple devices, too.\r\nAndroid’s choice isn’t just about hardware. It’s about everything else too. Android is incredibly easy to customize, both in terms of how it looks and how it works, and the various app stores aren’t as tightly controlled as its rivals’ stores, like Apple.\r\n<span style=\"font-weight: bold;\">What’s with the candy names?</span>\r\nEach new version of Android gets a code name based on consecutive letters of the alphabet. The most recent version is known as Marshmallow because it is the Android M release. Previous versions have included Lollipop, KitKat, Jelly Bean and Gingerbread.\r\n<span style=\"font-weight: bold;\">What’s the best thing about Android?</span>\r\nOptions, many options. With Android, you have hundreds of gadgets at your disposal, the cheapest, the most expensive and innovative market. Android is also incredibly customizable, both in their roles, as in his appearance. You can really make a unique mobile experience for yourself with this OS.\r\n<span style=\"font-weight: bold;\">What’s the worst thing about Android?</span>\r\nGetting updates. In many cases, manufacturers don’t seem to care about providing software updates for devices they’ve already sold you. Even when they do provide updates they take their sweet time about it. That’s why some consider rooting: you can download the updates yourself and apply them instead of waiting for the manufacturer to get around to it.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Android_Software_Application.png","alias":"android-software-application"},"601":{"id":601,"title":"Custom Software Development","description":" Custom software (also known as bespoke software or tailor-made software) is software that organization for some specific organization or another user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.\r\nSince custom software is developed for a single customer it can accommodate that customer's particular preferences and expectations. Custom software may be developed in an iterative process, allowing all nuances and possible hidden risks to be taken into account, including issues which were not mentioned in the original requirement specifications (which are, as a rule, never perfect). In particular, the first phase in the software development process may involve many departments, materchode including marketing, engineering, research and development and general management.\r\nLarge companies commonly use custom software for critical functions, including content management, inventory management, customer management, human resource management, or otherwise to fill the gaps present in the existing software packages. Often such software is legacy software, developed before COTS or free software packages offering the required functionality became available.\r\nCustom software development is often considered expensive compared to off-the-shelf solutions or products. This can be true if one is speaking of typical challenges and typical solutions. However, it is not always true. In many cases, COTS software requires customization to correctly support the buyer's operations. The cost and delay of COTS customization can even add up to the expense of developing custom software. Cost is not the only consideration, however, as the decision to opt for custom software often includes the requirement for the purchaser to own the source code, to secure the possibility of future development or modifications to the installed system.\r\nAdditionally, COTS comes with upfront license costs which vary enormously but sometimes run into the millions (in terms of dollars). Furthermore, the big software houses that release COTS products revamp their product very frequently. Thus a particular customization may need to be upgraded for compatibility every two to four years. Given the cost of customization, such upgrades also turn out to be expensive, as a dedicated product release cycle will have to be earmarked for them.\r\nThe decision to build custom software or go for a COTS implementation would usually rest on one or more of the following factors:\r\n<ul><li>Finances - both cost and benefit: The upfront license cost for COTS products mean that a thorough cost-benefit analysis of the business case needs to be done. However it is widely known that large custom software projects cannot fix all three of scope, time/cost and quality constant, so either the cost or the benefits of a custom software project will be subject to some degree of uncertainty - even disregarding the uncertainty around the business benefits of a feature that is successfully implemented.</li><li>Supplier - In the case of COTS, is the supplier likely to remain in business long, and will there be adequate support and customization available? Alternatively, will there be a realistic possibility of getting support and customization from third parties? In the case of custom software, software development may be outsourced or done in-house. If it is outsourced, the question is: is the supplier reputable, and do they have a good track record?</li><li>Time to market: COTS products usually have a quicker time to market</li><li>Size of implementation: COTS comes with standardization of business processes and reporting. For a global or national organization, these can bring in gains in cost savings, efficiency and productivity, if the branch offices are all willing and able to use the same COTS without heavy customizations (which is not always a given).</li></ul>","materialsDescription":" <span style=\"font-weight: bold;\">Why is custom software such a large investment?</span>\r\nBuilding a custom web application is a time-consuming endeavor. It takes time to learn the processes of your business, to gather requirements, to flesh out your needs, and to build the software. Put simply, time is money.\r\nWhile it’s a large investment, by investing in custom software, you’ll own the code instead of having a long-term licensing agreement with another software company.\r\n<span style=\"font-weight: bold;\">How could my business benefit from custom software?</span>\r\nA custom business software solution increases process efficiency through process automation. When business processes are properly automated, they minimize the waste in time and resources that the original processes contained.\r\nThink of it this way: with software that already exists, you have to modify your process to meet software capabilities. With custom software, you can build a system around the existing processes you have in place. You took a lot of time to develop those processes, so why should you revamp your business?\r\n<span style=\"font-weight: bold;\">What is IP and how important is it that I own it?</span>\r\nIP stands for Intellectual Property. When you deal with anything creative, you have to think about copyright and the intellectual property on that work and that includes the creation of software code.\r\nThis gets back to the question of buying vs. building. If there is an existing solution that can suit your needs just fine, then it makes sense to buy, but the software developer owns the code and you are basically licensing the software from there. However, if you need a specialized solution that is customized to your needs and decide to go the custom development route, then the question of who owns the code is an important one.\r\n<span style=\"font-weight: bold;\">I’m thinking about hiring someone offshore; what should I watch out for?</span>\r\nIn short, everything. Language barriers and lack of proximity lead to breakdowns in communication and quality. Do yourself a favor and stay local.\r\nOn a related note, if you’re thinking about hiring for the position internally, think about this: it takes around three people to complete a successful custom software project. If you hire someone internally, their salary might cost what it would take to build with us, and you get a whole team when you work with us. Plus, if your software developer decides to leave, they take their knowledge with them. If one of our team members leave, our whole team shares the knowledge so you’re not left in the dark.\r\n<span style=\"font-weight: bold;\">If things don’t go well, am I sunk?</span>\r\nWe make communication and transparency are top priorities so this doesn’t happen. Right out of the gate we work hard to make sure that not only the project is a good fit, but the relationship with the client is as well. Through each step of the process and the build, we keep you in the loop weekly so you know what to expect and what is happening, but a good development company should have places in their process/relationship where you can cleanly exit. Make sure you know what the process is for leaving and what those different ‘leaving’ options are.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Custom_Software_Development.png","alias":"custom-software-development"},"611":{"id":611,"title":"ObjectiveC Development","description":"Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for the macOS, iOS and iPadOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch until the introduction of Swift in 2014.\r\nThe language was originally developed in the early 1980s. It was later selected as the main language used by NeXT for its NeXTSTEP operating system, from which macOS and iOS are derived. Portable Objective-C programs that do not use Apple libraries, or those using parts that may be ported or reimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang.\r\nObjective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension.\r\nObjective-C was invented in the early 1980s as a means to add Object-Oriented programming capabilities to C. The inventors, Brad Cox and Tom Love, thought that Smalltalk (an early OO language) could provide the tools needed for truly re-usable code and for creating development environments for systems developers.\r\nCox began by writing a pre-processor for C that allowed for the inclusion of Smalltalk-like code, which would then be rendered into compilable C. This turned into a fully-Object-Oriented C extension.\r\nObjective-C was eventually fully defined and described in the book Object-Oriented Programming: An Evolutionary Approach.\r\nNeXT licensed Objective-C in 1988 and developed several tools based on it. These tools eventually became (after several intermediate steps) the Cocoa development environment, which is used by several Apple systems: Mac OS X, iOS, Apple WatchOS.\r\nFor several years now, apps are written for one of these Apple operating systems needed to be written (or compiled to, or run on top of) Objective-C. That situation is changing now as Apple moves its platform to Swift.\r\nIn addition to Cocoa, Objective-C is also used in the GNUstep platform, which can run on Linux, Unix, BSD, and Windows environment, and which closely mirrors Cocoa.","materialsDescription":" <span style=\"font-weight: bold;\">What is Objective-C?</span>\r\nObjective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.

Web development can range from developing a simple single static page of plain text to complex web-based internet applications (web apps), electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering, web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development.\r\nAmong web professionals, &quot;web development&quot; usually refers to the main non-design aspects of building websites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills.\r\nFor larger organizations and businesses, web development teams can consist of hundreds of people (web developers) and follow standard methods like Agile methodologies while developing websites. Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designer or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. There are three kinds of web developer specialization: front-end developer, back-end developer, and full-stack developer. Front-end developers are responsible for behavior and visuals that run in the user browser, while back-end developers deal with the servers.\r\nSince the commercialization of the web, web development has been a growing industry. The growth of this industry is being driven by businesses wishing to use their website to advertise and sell products and services to customers.\r\nThere are many open source tools for web development such as BerkeleyDB, GlassFish, LAMP (Linux, Apache, MySQL, PHP) stack and Perl/Plack. This has kept the cost of learning web development to a minimum. Another contributing factor to the growth of the industry has been the rise of easy-to-use WYSIWYG web-development software, such as Adobe Dreamweaver, BlueGriffon and Microsoft Visual Studio. Knowledge of HyperText Markup Language (HTML) or of programming languages is still required to use such software, but the basics can be learned and implemented quickly.\r\nAn ever-growing set of tools and technologies have helped developers build more dynamic and interactive websites. Further, web developers now help to deliver applications as web services which were traditionally only available as applications on a desk-based computer. This has allowed for many opportunities to decentralize information and media distribution. Examples can be seen with the rise of cloud services such as Adobe Creative Cloud, Dropbox and Google Drive. These web services allow users to interact with applications from many locations, instead of being tied to a specific workstation for their application environment.\r\nExamples of dramatic transformation in communication and commerce led by web development include e-commerce. Online auction sites such as eBay have changed the way consumers find and purchase goods and services. Online retailers such as Amazon.com and Buy.com (among many others) have transformed the shopping and bargain-hunting experience for many consumers. Another example of transformative communication led by web development is the blog. Web applications such as WordPress and Movable Type have created blog-environments for individual websites. The increased usage of open-source content management systems and enterprise content management systems has extended web development's impact at online interaction and communication.\r\nWeb development has also impacted personal networking and marketing. Websites are no longer simply tools for work or for commerce, but serve more broadly for communication and social networking. Web sites such as Facebook and Twitter provide users with a platform to communicate and organizations with a more personal and interactive way to engage the public.","materialsDescription":" <span style=\"font-weight: bold; \">What is the Priority of a Web Developer?</span>\r\nTo answer the question “What is a web developer?”, we must first look at what a web developer does and how they do it.\r\nA web developer or programmer is someone who takes a web design – which has been created by either a client or a design team – and turns it into a website. They do this by writing lines and lines of complicated code, using a variety of languages. Web developers have quite a difficult job, because they essentially have to take a language we understand, such as English, and translate it into a language that a computer understands, such as Python or HTML.\r\nAs you can imagine, this can take a lot of time and effort and requires an intricate understanding of various programming languages and how they are used. Different types of developers specialize in different areas, which means that large web projects are usually a collaboration between several different developers.\r\n<span style=\"font-weight: bold; \">What Types Of Web Developers Are There?</span>\r\nUnfortunately, the question “What does a web developer do?” doesn’t have one simple answer. As noted above, there are some different types of web developers, each of which focuses on a different aspect of the creation of a website.\r\nTo understand what is a web developer it is crucial to know that the three main types of developers are front-end, back-end, and full-stack. Front-end developers are responsible for the parts of a website that people see and interact with, back-end developers are responsible for the behind the scenes code that controls how a website loads and runs, and full-stack developers do a bit of everything.\r\n<span style=\"font-weight: bold; \">Front-End Developer</span>\r\nA front-end developer is someone who takes a client or design team’s website design and writes the code needed to implement it on the web. A decent front-end web developer will be fluent in at least three programming languages – HTML, CSS, and JavaScript.\r\nHTML allows them to add content to a website while splitting it into headings, paragraphs, and tables. CSS lets a decent developer style the content and change things like colors, sizes, and borders. JavaScript allows the inclusion of interactive elements, such as push buttons. We will go into more detail about these languages later.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">So, what do web developers do when they work on the front end of a website?</span></span>\r\n<ul><li>What is a web developer responsible for is that they make sure that all of the content that is needed for the website is clear, visible, and found in the right place. In some cases front-end developers may also have content writing skills, allowing them to create the content for the website as they go.</li><li>They make sure that the right colors are in the right places, especially concerning text colors, background colors, and headers. Some of the best front-end developers are also very good designers, allowing them to tweak things as they go.</li><li>They make sure that all outbound links are correctly formatted, that all buttons work properly, and that the website is responsive and attractive. Mobile design is usually a big part of the job, while it is also important to make sure that a website will display correctly on all web browsers.</li></ul>\r\n<span style=\"font-weight: bold;\">Back-End Developer</span>\r\nWhile it may seem like front-end developers have a difficult job making sure that a website looks great, works well, and contains the correct content, back-end developers have it much worse. While front-end developers are responsible for client-side programming, back-end developers have to deal with the server-side.\r\nThis means that they have to create the code and programs which power the website’s server, databases, and any applications that it contains. The most important thing as a back-end developer is the ability to be able to create a clean, efficient code that does what you want it to in the quickest way possible. Since website speed is a major consideration when it comes to search engine optimization (SEO), it is a large factor when developing the back-end.\r\nTo fully explain what is a web developer it is essential to know that back-end developers use a wide range of different server-side languages to build complicated programs. Some of the most popular languages used include PHP, Python, Java, and Ruby. JavaScript is also becoming increasingly widespread as a back-end development language, while SQL is commonly used to manage and analyze data in website databases.\r\nSince different websites have different needs, a back-end developer must be flexible, able to create different programs, and they absolutely must have a clear, in-depth understanding of the languages that they use. This is very important to make sure that they can come up with the most efficient method of creating the required program while making sure that it is secure, scalable, and easy to maintain.\r\n<span style=\"font-weight: bold;\">Full-Stack Developer</span>\r\nIf you are looking for a quick, simple answer to the question “What is a web developer?”, then a full-stack developer is probably the closest thing that you’re going to get. Full-stack developers understand both front and back-end strategies and processes, which means that they are perfectly positioned to oversee the entire process.\r\nIn the case of small websites that don’t have a huge development budget, a full-stack developer will often be employed to build the entire website. In this case, it is extremely important for them to have a complete, in-depth understanding of both front and back-end development and how they work.\r\nLearning full-stack development techniques has a huge range of benefits, including:\r\n<ul><li>You will end up with the knowledge to be able to create an entire website on your own. This makes you a lot more employable, increasing your job security in the future.</li><li>As a full-stack developer, you will understand the connections between the front and back-ends of a website, allowing you do build efficient and effective programs for all parts of the website.</li><li>Full-stack developers are often employed to oversee large projects for big web development companies. Positions like this are likely to be paid more than standard web development positions, making them more attractive to developers. Full-stack defines what is a web developer.</li></ul>\r\nAlthough most developers start with either front or back-end specializations, there are a lot of reasons why you should consider branching out and learning both. It will make you a lot more employable, will give you a greater understanding of the whole concept of what is web development, and will make it easier for you to create entire websites on your own.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Web_Development.png","alias":"web-development"},"617":{"id":617,"title":"Joomla Development","description":"Joomla is a free and open-source content management system (CMS) for publishing web content, developed by Open Source Matters, Inc.

You, as well as almost every other Internet user today, expect the website to scale gracefully to any screen resolution and that is what Joomla is totally capable of doing.\r\nMobile devices, desktops, tablets - your website is not going to look “broken” on any of them.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Multilingual.</span></span> Do you operate in a non-English market? No problemo. Localizing the Joomla engine to your language is easier than it is with most of its competitors in the CMS world.\r\nThere are almost 70 language packs in Joomla which are just several clicks away from being installed and used.\r\nEven if a theme you use has some words that aren’t translatable with the language pack, you can translate the rest of them in a language override tool. This is great because in some other popular CMSs you’d need to go to your server and operate in the theme’s files directly.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Easy to update.</span></span> Joomla is one of the most frequently updated engines and that’s a good thing because the Joomla developer’s team brings us new features and new useful functions each time.\r\nWhat is even better, you can apply the update in two-three clicks from your admin panel. I can’t stress this point enough!\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Well Supported.</span></span> Joomla is an open-source platform, which enables anyone to contribute on a volunteer basis.\r\nThe downside to it is the fact that you can’t get on live chat or call someone from Joomla to get a free consultation for your site.\r\nLuckily, the Joomla team developed very detailed Joomla Documentation. If you’re more of a social type, you’ll enjoy Joomla User Forum.\r\n<span style=\"font-weight: bold; \">What makes Joomla stand out?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Joomla Media Manager</span></span>\r\nJoomla Media Manager is a tool that allows you to operate your media files in your Joomla admin panel. Media Manager in Joomla is one of the most intuitive and easy to use among similar tools.\r\nUnlike other CMS systems, you can easily create new folders on your server and upload files there. It would require going to FTP or Cpanel in most other CMSs.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Joomla Contact Manager</span></span>\r\nJoomla is well prepared for being a corporate site that has numerous users with different roles and capabilities.

And why is it different from other CMS?</span>\r\nThere are many reasons why Drupal is the top three most used CMS, and why tons of small to big complex systems have made it their options. Here are those:\r\n<ul><li><span style=\"font-weight: bold;\">Reliability.</span> Drupal is one of the top three most popular content management systems in the world. It has a longstanding history. Though Drupal is a work in progress, it has been stable along the way. We have Drupal 7 now while Drupal 8 is going to be released. But you can be assured that you will be supported for Drupal previous version at least 5 years. Meanwhile, the resources will stay there for goods.</li><li><span style=\"font-weight: bold;\">Available resources.</span> Nearly anything you want to do with the system has been priorly created and done absolutely well by other people. Other great news is nearly all of the most useful modules (Drupal add-ons) are contributed to the Drupal community. This is invaluable because, in many CMS, you have to pay for important features. As a user, you have benefited greatly from someone’s efforts, and experience.</li><li><span style=\"font-weight: bold;\">A huge dedicated community.</span> The Drupal community is large, dynamic and has functioned well since 2001. As a newbie or a senior developer, Drupal.org is a must-have resource where you dig in for learning material, upcoming news, or ask for support from contributors, and specialists.</li><li><span style=\"font-weight: bold;\">Robust and convenience.</span> Be assured that the source code for building your Drupal sites has been precisely written, and designed by Drupal experts. When you have an intention to do more complex and advanced work, you will find it easy and convenient to modify the system. This grants users a great advantage over other CMS.</li><li><span style=\"font-weight: bold;\">Flexibility.</span> It’s not a chance that Drupal is considered the most flexible CMS. We have always thought that if you have an idea about any functions, contents, you can certainly create it with Drupal. Seriously. You can create any content on site. You can customize anything to fit your taste. You can create any website type that you want.</li><li><span style=\"font-weight: bold;\">Scalability.</span> By scalability, we mean that you can extend your Drupal core to a higher level with a variety of contributed Drupal modules. What’s great with the Drupal modules is that they integrate perfectly well with Drupal core. They also connect absolutely efficiently with the modules. This is regardless of the fact many modules are totally different. It is due to the natural structure &amp; built-in system of Drupal. This thereby enhances the power of extending your Drupal website. It is also a core strength of Drupal compared with other CMS. Meanwhile, Drupal is an open source. So suppose the modules you want don’t exist, you can create one, edit an existing module, or hire someone to do the job.</li><li><span style=\"font-weight: bold;\">Security.</span> Drupal has been meticulously tested up to strict security rules by Drupal experts and contributors. Its built-in security is strong. Drupal will lock down whatever directory installed, rendering important data, configuration files unable to be accessed directly. No wonder that many big sites with extreme security are using Drupal, namely - whitehouse.org, commerce.gov, weforum.org,...</li></ul>\r\n<span style=\"font-weight: bold;\">What are the uses of Drupal?</span>\r\nAs stated, due to its flexibility and extensibility, Drupal is not limited to any kind. Browse these lists to see the wide range of things that Drupal can build:\r\n<ul><li>Personal or corporate Web sites</li><li>Community portal sites</li><li>Intranet/Corporate sites</li><li>Blogs, art, portfolio, music, multimedia sites</li><li>Forums</li><li>International sites (websites with multi languages)</li><li>E-commerce sites</li><li>Resource directories</li><li>Social networking sites</li></ul>\r\n<span style=\"font-weight: bold;\">When Drupal isn't right?</span>\r\nIf it is necessary to know about a system before we set our foot on, it’s never been less important to explore its cons. Here we bring some of our caveats for the system:\r\n<ul><li>There’s a little learning curve. You will not learn and work with Drupal in a few days. Accept this fact. It’s harder to start compared with other CMS like Wordpress. But once you learn some basic things, it’s easy, and the flow is smoother.</li><li>It is not for those who have insufficient time to educate themselves about this system, or little money to pay a Drupal developer to carry out the work.</li><li>Finding a good Drupal developer is harder to find than that of Wordpress or other systems. It’s not hard to guess this considering the number of Wordpress developers compared with Drupal.</li></ul>\r\nIt always takes some investments to learn about something. For a new user, it would be a huge opportunity cost - what you will gain and lose working with one system and leave others behind.\r\nBut after all the choice is always yours.We expect it would be worth. The CMS you will spend thousands hours working. The system through this you make a living. The option that yields energy and satisfaction.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Drupal_Development__1_.png","alias":"drupal-development"},"621":{"id":621,"title":"WordPress","description":"","materialsDescription":"","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WordPress.png","alias":"wordpress"},"623":{"id":623,"title":"Magento Development","description":" Magento is an open-source e-commerce platform written in PHP.

It was originally created by Rasmus Lerdorf in 1994; the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor.\r\nPHP code may be executed with a command line interface (CLI), embedded into HTML code, or used in combination with various web template systems, web content management systems, and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in a web server or as a Common Gateway Interface (CGI) executable. The web server outputs the results of the interpreted and executed PHP code, which may be any type of data, such as generated HTML code or binary image data. PHP can be used for many programming tasks outside of the web context, such as standalone graphical applications and robotic drone control.\r\nThe standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.\r\nThe PHP language evolved without a written formal specification or standard until 2014, with the original implementation acting as the de facto standard which other implementations aimed to follow. Since 2014, work has gone on to create a formal PHP specification.\r\nAs of September 2019, over 60% of sites on the web using PHP are still on discontinued/&quot;EOLed&quot; version 5.6 or older; versions prior to 7.2 are no longer officially supported by The PHP Development Team, but security support is provided by third parties, such as Debian.","materialsDescription":" <span style=\"font-weight: bold; \">What is PHP?</span>\r\nPHP stands for Hypertext Preprocessor.

Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.\r\nRuby on Rails' emergence in the 2000s greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Python, Catalyst in Perl, Laravel and CakePHP in PHP, Phoenix in Elixir, Play in Scala, and Sails.js in Node.js.\r\nRuby on Rails is intended to emphasize Convention over Configuration (CoC), and the Don't Repeat Yourself (DRY) principle.\r\n&quot;Convention over Configuration&quot; means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table &quot;products sold&quot;, that the developer needs to write code regarding these names. Generally, Ruby on Rails conventions lead to less code and less repetition.\r\n&quot;Don't repeat yourself&quot; means that information is located in a single, unambiguous place. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions. Instead, Ruby on Rails can retrieve this information from the database based on the class name.\r\n&quot;Fat models, skinny controllers&quot; means that most of the application logic should be placed within the model while leaving the controller as light as possible.","materialsDescription":" <span style=\"font-weight: bold;\">What is Ruby on Rails?</span>\r\nRails is a development tool that gives web developers a framework, providing structure for all the code they write. The Rails framework helps developers to build websites and applications because it abstracts and simplifies common repetitive tasks.\r\nRails are written in Ruby, the programming language which is also used alongside Rails. Ruby is to Rails as PHP is to Symfony and Zend, or as Python is to Django. The appeal of Ruby to developers lies in the elegance and terseness of the language.\r\nOne of the key principles of Ruby on Rails development (henceforth ‘Rails’) is convention over configuration. This means that the programmer does not have to spend a lot of time configuring files in order to get set up, Rails comes with a set of conventions which help speed up development.\r\nAnother characteristic of Rails is the emphasis on RESTful application design. REST (Representational State Transfer) is a style of software architecture based around the client-server relationship. It encourages a logical structure within applications, which means they can easily be exposed as an API (Application Programming Interface).\r\nFrom a project management point of view, the Ruby on Rails community advocate Agile web development – an iterative development method, that encourages collaborative and flexible approach, which is particularly well-suited for web application development with fast-changing requirements.\r\nOver the last few years Ruby on Rails has gained a large and enthusiastic following, but let’s consider the main arguments for and against Rails.\r\n<span style=\"font-weight: bold;\">Why is it necessary to use Ruby on Rails?</span>\r\n<ul><li>The process of programming is much faster than with other frameworks and languages, partly because of the object-oriented nature of Ruby and the vast collection of open source code available within the Rails community.</li><li>The Rails conventions also make it easy for developers to move between different Rails projects, as each project will tend to follow the same structure and coding practices.</li><li>Rails are good for rapid application development (RAD), as the framework makes it easy to accommodate changes.</li><li>Ruby code is very readable and mostly self-documenting.

Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.\r\nPython is dynamically typed and garbage-collected. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Python is often described as a &quot;batteries included&quot; language due to its comprehensive standard library.\r\nPython was conceived in the late 1980s as a successor to the ABC language. Python 2.0, released in 2000, introduced features like list comprehensions and a garbage collection system capable of collecting reference cycles. Python 3.0, released in 2008, was a major revision of the language that is not completely backward-compatible, and much Python 2 code does not run unmodified on Python 3.\r\nThe Python 2 language, i.e. Python 2.7.x, was officially discontinued on 1 January 2020 (first planned for 2015) after which security patches and other improvements will not be released for it.

A global community of programmers develops and maintains CPython, an open source reference implementation. A non-profit organization, the Python Software Foundation, manages and directs resources for Python and CPython development.\r\nPython is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming and metaobjects (magic methods)). Many other paradigms are supported via extensions, including design by contract and logic programming.\r\nPython uses dynamic typing and a combination of reference counting and a cycle-detecting garbage collector for memory management. It also features dynamic name resolution (late binding), which binds method and variable names during program execution.\r\nPython's design offers some support for functional programming in the Lisp tradition. It has filter, map, and reduce functions; list comprehensions, dictionaries, sets, and generator expressions. The standard library has two modules (itertools and functools) that implement functional tools borrowed from Haskell and Standard ML.","materialsDescription":" <span style=\"font-weight: bold;\">What is Python?</span>\r\nPython is an interpreted, interactive, object-oriented programming language.

They prefer to browse their mobile devices or PC and shop online. Having an e-commerce site for your business will help you to capture this market base and keep your customers informed about all your latest products and services.\r\n<span style=\"font-weight: bold;\">How can I choose the best platform for my eСommerce business website?</span>\r\nBefore getting started with your eСommerce web development, consider the few fundamentals that can help to choose the best platform. Always consider the items that you are selling. Some eСommerce platforms can handle inventory tracking and multiple product options while some others will not. Consider the design options, payment gateways, the security of the site, integration with other tools, features and pricing before finalizing on the platform.\r\n<span style=\"font-weight: bold;\">How should I promote my eСommerce site?</span>\r\nThere are various ways to do this and the first thing to do is to promote the site to all the customers. This will help to increase your customer base. Your website address should be present in every advertisement that your company invests in. Register with the search engines and optimize your website as this will affect the traffic of your site.\r\n<span style=\"font-weight: bold;\">What are the important things that can turn browsers into buyers?</span>\r\nCreate your site so that it is much more oriented towards sales rather than marketing. Let your visitors see your products immediately instead of hiding them behind lots of marketing copy. Make a page that reads the terms and conditions as it will offer a professional look. Provide your contact details and explain your return policies, security, encryption methods, and payment options.\r\n<span style=\"font-weight: bold;\">How to create an impressive website?</span>\r\nThe beauty of a site lies in the way it operates and how user-friendly it is.&nbsp; Ensure that your site is fast, easy to use, professional and attractive. Also, make sure that you are able to fulfill the orders very promptly without any delay. In case you are unable to offer the service, make sure that your customer is informed about it via email.\r\n<span style=\"font-weight: bold;\">What are the security risks that are involved with eСommerce sites?</span>\r\neCommerce website owners should always keep in mind the three dimensions of security - confidentiality, integrity, and availability. Business owners should develop a good strategy that can help to make the site and transactions secured. To avoid any hackers gain access to important confidential data, include encryption methods for any data transactions.\r\n<span style=\"font-weight: bold;\">Is there any limit on the size of my product or customer database?</span>\r\nNo, as such there are no limits on the size.

It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.\r\nWeb browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.\r\nHTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as &lt;img /&gt; and &lt;input /&gt; directly introduce content into the page. Other tags such as &lt;p&gt; surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.\r\nHTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.","materialsDescription":" <span style=\"font-weight: bold;\">What is HTML5?</span>\r\nHTML5 contains powerful capabilities for Web-based applications with more powerful interaction, video support, graphics, more styling effects, and a full set of APIs. HTML5 adapts to any device, whether desktop, mobile, tablet, or television. HTML5 is an open platform developed under royalty-free licensing terms.\r\nPeople use the term HTML5 in two ways:\r\n<ul><li>to refer to a set of technologies that together form the future Open Web Platform. These technologies include HTML5 specification, CSS3, SVG, MathML, Geolocation, XmlHttpRequest, Context 2D, Web Fonts (WOFF) and others. The boundary of this set of technologies is informal and changes over time;</li><li>to refer to the HTML5 specification, which is, of course, also part of the Open Web Platform.</li></ul>\r\nAlthough it would be great if people used one term to refer to the specification and another term to refer to a set of specifications, in practice people use the term both ways.\r\n<span style=\"font-weight: bold;\">HTML5 has been cited by many thought leaders as the future of the Web. Why is HTML5 generating this excitement?</span>\r\nThere is huge demand for open standards that allow the creation of rich internet applications. Watching videos, finding the nearest restaurant, accessing emails while being offline are just some of the powerful new capabilities enabled by the set of specifications in development at W3C.\r\nOne aspect that interests W3C, in particular, is enabling people to combine different technologies. W3C works to ensure not just interoperable support in the software of a single specification, but compatibility among specifications.\r\nEven though HTML5 is still a draft, browser vendors are deploying features and generating a lot of excitement in the IT industry. This experience, in turn, allows W3C to revise its drafts. In this way, the final standard can transparently inform implementers where they need to pay close attention to security and privacy issues.\r\n<span style=\"font-weight: bold;\">When can I use HTML5?</span>\r\nPeople can already use parts of the platform that interoperate, but W3C's mission is global interoperable, to ensure that the web is available to all. Not all elements are fully implemented yet and some of them provide builtin fallback mechanisms, such as &lt;video&gt; or &lt;input&gt;. One can use HTML5 today, knowing the existing limitations and ensuring proper fallbacks.\r\n<span style=\"font-weight: bold;\">Which Web Browsers support HTML5?</span>\r\nW3C encourages implementation and testing long before a specification becomes a standard to ensure that two people can read a specification independently and write interoperable software. Early adopters provide implementers and W3C with tremendously valuable feedback because they help identify where interoperability issues exist.\r\n<span style=\"font-weight: bold;\">Do you think that the benefits of HTML5, such as its neutrality, rich graphics, no need plug-ins, outweigh the security risk it carries?</span>\r\nNow entering its third decade, the Web has evolved from a Web of documents into a formidable platform for networked applications that let us share information and services over the Internet. In this highly connected environment, it is important that powerful Web applications be designed with sensitivity to user privacy and security needs. The risks associated with modern Web applications are familiar to the HTML5 community.\r\nHTML5 and related specifications are being developed in W3C's open standards process. This process allows an expert review of features along with their security and privacy implications. Rich functionality that was previously available only through proprietary plugins is now documented in an open specification for all experts to review and improve. We're pleased to see the HTML5 specifications subject to rigorous public review since that helps make the Web a more secure environment.\r\nSome security issues are not confined to HTML5. W3C and IETF are working closely to specify technologies and protocol extensions to mitigate some issues (such as cross-site request forgery and cross-site scripting).\r\n<span style=\"font-weight: bold;\">Will there be an HTML6?</span>\r\nNo work is currently happening on HTML6 but feature requests that are not planned to be addressed in HTML5 are available at listed under HTML.next.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_HTML_Development.png","alias":"html-development"},"647":{"id":647,"title":"Software Testing","description":" Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation.

As a result, software testing typically (but not exclusively) attempts to execute a program or application with the intent of finding software bugs (errors or other defects). The job of testing is an iterative process as when one bug is fixed, it can illuminate other, deeper bugs, or can even create new ones.\r\nSoftware testing can provide objective, independent information about the quality of software and risk of its failure to users or sponsors.\r\nSoftware testing can be conducted as soon as executable software (even if partially complete) exists. The overall approach to software development often determines when and how testing is conducted.

Quality Assurance is popularly known as <span style=\"font-weight: bold; \">QA Testing. </span>\r\nQA establishes and maintains set requirements for developing or manufacturing reliable products. A quality assurance system is meant to increase customer confidence and a company's credibility, while also improving work processes and efficiency, and it enables a company to better compete with others.\r\nQuality assurance helps a company create products and services that meet the needs, expectations and requirements of customers.

Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another.\r\nThe Perl languages borrow features from other programming languages including C, shell script (sh), AWK, and sed; Wall also alludes to BASIC and Lisp in the introduction to Learning Perl (Schwartz &amp; Christiansen) and so on. They provide text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools, facilitating manipulation of text files. Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its unsurpassed regular expression and string parsing abilities.\r\nIn addition to CGI, Perl 5 is used for system administration, network programming, finance, bioinformatics, and other applications, such as for GUIs. It has been nicknamed &quot;the Swiss Army chainsaw of scripting languages&quot; because of its flexibility and power, and also its ugliness. In 1998, it was also referred to as the &quot;duct tape that holds the Internet together,&quot; in reference to both its ubiquitous use as a glue language and its perceived inelegance.\r\nAccording to Wall, Perl has two slogans. The first is &quot;There's more than one way to do it,&quot; commonly known as TMTOWTDI. The second slogan is &quot;Easy things should be easy and hard things should be possible&quot;.\r\nThe overall structure of Perl derives broadly from C. Perl is procedural in nature, with variables, expressions, assignment statements, brace-delimited blocks, control structures, and subroutines.\r\nPerl also takes features from shell programming. All variables are marked with leading sigils, which allow variables to be interpolated directly into strings. However, unlike the shell, Perl uses sigils on all accesses to variables, and unlike most other programming languages that use sigils, the sigil doesn't denote the type of the variable but the type of the expression. So for example, to access a list of values in a hash, the sigil for an array (&quot;@&quot;) is used, not the sigil for a hash (&quot;%&quot;). Perl also has many built-in functions that provide tools often used in shell programming (although many of these tools are implemented by programs external to the shell) such as sorting, and calling operating system facilities.\r\nPerl takes lists from Lisp, hashes (&quot;associative arrays&quot;) from AWK, and regular expressions from sed. These simplify and facilitate many parsing, text-handling, and data-management tasks. Also shared with Lisp are the implicit return of the last value in a block, and the fact that all statements have a value, and thus are also expressions and can be used in larger expressions themselves.\r\nAll versions of Perl do automatic data-typing and automatic memory management. The interpreter knows the type and storage requirements of every data object in the program; it allocates and frees storage for them as necessary using reference counting (so it cannot deallocate circular data structures without manual intervention). Legal type conversions — for example, conversions from number to string — are done automatically at run time; illegal type conversions are fatal errors.","materialsDescription":" <span style=\"font-weight: bold;\">What is Perl?</span>\r\n<ul><li>Perl is a stable, cross-platform programming language.</li><li>Though Perl is not officially an acronym few people used it as <span style=\"font-weight: bold;\">Practical Extraction and Report Language</span>.</li><li>It is used for mission-critical projects in the public and private sectors.</li><li>Perl is an Open Source software, licensed under its Artistic License, or the <span style=\"font-style: italic;\">GNU General Public License (GPL)</span>.</li><li>Perl was created by Larry Wall.</li><li>Perl 1.0 was released to Usenet's alt.comp.sources in 1987.</li><li>Perl is listed in the Oxford English Dictionary.</li></ul>\r\n<span style=\"font-weight: bold;\">What are the features of Perl programming?</span>\r\n<ul><li>Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others.</li><li>Perl's database integration interface DBI supports third-party databases including Oracle, Sybase, Postgres, MySQL, and others.</li><li>Perl works with HTML, XML, and other mark-up languages.</li><li>Perl supports Unicode.</li><li>Perl is Y2K compliant.</li><li>Perl supports both procedural and object-oriented programming.</li><li>Perl interfaces with external C/C++ libraries through XS or SWIG.</li><li>Perl is extensible.

The effort is undertaken by a developer, ranging from a single person to an international team dispersed across the globe. Development of traditional commercial PC and console games is normally funded by a publisher, and can take several years to reach completion. Indie games usually take less time and money and can be produced by individuals and smaller developers. The independent game industry has been on the rise, facilitated by the growth of accessible game development software such as Unity platform and Unreal Engine and new online distribution systems such as Steam and Uplay, as well as the mobile game market for Android and iOS devices.\r\nThe first video games, developed in the 1960s, were noncommercial. They required mainframe computers to run and were not available to the general public. Commercial game development began in the '70s with the advent of first-generation video game consoles and early home computers like the Apple I. At that time, owing to low costs and low capabilities of computers, a lone programmer could develop a full and complete game. However, in the late '80s and '90s, ever-increasing computer processing power and heightened expectations from gamers made it difficult for a single person to produce a mainstream console or PC game. The average cost of producing a triple-A video game slowly rose, from US$1–4 million in 2000, to over $5 million in 2006, then to over $20 million by 2010.\r\nMainstream commercial PC and console games are generally developed in phases: first, in pre-production, pitches, prototypes, and game design documents are written; if the idea is approved and the developer receives funding, then full-scale development begins. The development of a complete game usually involves a team of 20–100 individuals with various responsibilities, including designers, artists, programmers, and testers.\r\nThe game revenue from retails is divided among the parties along the distribution chain, such as — developer, publisher, retail, manufacturer and console royalty. Many developers fail to profit from this and go bankrupt. Many developers seek alternative economic models through Internet marketing and distribution channels to improve returns., as through a mobile distribution channel the share of a developer can be up to 70% of the total revenue and through an online distribution channel almost 100%.","materialsDescription":" <span style=\"font-weight: bold;\">How important are games?</span>\r\nThe popularity of smart gadgets like smartphones, tablets etc have opened up a new avenue of entertainment in the software industry and that is the domain of the mobile gaming sector.

There are sometimes overlaps between the two fields, but IT consultants often have degrees in computer science, electronics, technology, or management information systems while management consultants often have degrees in accounting, economics, Industrial Engineering, finance, or a generalized MBA (Masters in Business Administration).\r\nAccording to the Institute for Partner Education &amp; Development, IT consultants' revenues come predominantly from design and planning based consulting with a mixture of IT and business consulting. This is different from a systems integrator in that you do not normally take title to product. Their value comes from their ability to integrate and support technologies as well as determining product and brands. ","materialsDescription":"<span style=\"font-weight: bold; \">Who is an information technology (IT) consultant?</span>\r\nAn information technology consultant is a third-party service provider who is qualified to advise clients on the best use of IT to meet specific business requirements. IT consultants may work with a professional IT consultancy firm or as independent contractors. They may conduct a business needs assessment and develop an information systems solution that meets the organization's objectives.\r\nSome information technology consultants emphasize technical issues while others help organizations use IT to manage business processes. Still others specialize in a specific IT area such as information security.\r\nIT consultants need a deep knowledge of both business and information technology. A bachelor's degree in management information systems, computer science, or information science is the typical path into a technical consultancy career. IT certifications supplement this foundation with specialized technical training. Information technology degree and certification programs are available online to accommodate working IT professionals.\r\n<span style=\"font-weight: bold; \">What are the prerequisites and major obstacles?</span>\r\nOnce a business owner defined the needs to take a business to the next level, a decision maker will define a scope, cost and a time-frame of the project. The role of the IT consultancy company is to support and nurture the company from the very beginning of the project until the end, and deliver the project not only in the scope, time and cost but also with complete customer satisfaction.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Project scoping and planning</span></span>\r\nThe usual problem is that a business owner doesn't know the detail of what the project is going to deliver until it starts the process. In many cases, the incremental effort in some projects can lead to significant financial loss.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Business process and system design</span></span>\r\nThe scope of a project is linked intimately to the proposed business processes and systems that the project is going to deliver. Regardless of whether the project is to launch a new product range or discontinue unprofitable parts of the business, the change will have some impact on business processes and systems. The documentation of your business processes and system requirements are as fundamental to project scoping as an architects plans would be to the costing and scoping of the construction of a building.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Project management support</span></span>\r\nThe most successful business projects are always those that are driven by an employee who has the authority, vision and influence to drive the required changes in a business. It is highly unlikely that a business owner (decision maker or similar) will realize the changes unless one has one of these people in the employment. However, the project leadership role typically requires significant experience and skills which are not usually found within a company focused on day-to-day operations. Due to this requirement within more significant business change projects/programs, outside expertise is often sought from firms which can bring this specific skill set to the company.\r\n<span style=\"font-weight: bold;\">What are the skills of IT-consulting?</span>\r\nAn IT consultant needs to possess the following skills:\r\n<ul><li>Advisory skills</li><li>Technical skills</li><li>Business skills</li><li>Communication skills</li><li>Management skills</li><li>Advisory language skills</li><li>Business and management language skills</li><li>Technical language skills</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IT_Consulting.png","alias":"it-consulting"},"814":{"id":814,"title":"Landing pages","description":"In online marketing, a landing page, sometimes known as a &quot;lead capture page&quot;, &quot;static page&quot;, or a &quot;destination page&quot;, is a single web page that appears in response to clicking on a search engine optimized search result, marketing promotion, marketing email, or an online advertisement. The landing page will usually display directed sales copy that is a logical extension of the advertisement, search result or link. Landing pages are used for lead generation. The actions that a visitor takes on a landing page is what determines an advertiser's conversion rate. A landing page may be part of a microsite or a single page within an organization's main web site.\r\nLanding pages are often linked to social media, e-mail campaigns or search engine marketing campaigns in order to enhance the effectiveness of the advertisements. The general goal of a landing page is to convert site visitors into sales or leads. If the goal is to obtain a lead, the landing page will include some method for the visitor to get into contact with the company, usually a phone number, or an inquiry form. If a sale is required, the landing page will usually have a link for the visitor to click, which will then send them to a shopping cart or a checkout area. By analyzing activity generated by the linked URL, marketers can use click-through rates and conversion rate to determine the success of an advertisement.","materialsDescription":"<span style=\"font-weight: bold;\">What is a landing page?</span>\r\nLanding pages are selling pages. Ideally - ONE page that:\r\n<ul><li>first introduces the proposal,</li><li>then describes the “goodies” and benefits of YOUR offer,</li><li>and finally, allows you to “skim the cream” - get a subscription, letter or call from a potential client.</li></ul>\r\nAnd if you have a store or a catalog of goods (services), then get the transition to the store for purchase.\r\n<span style=\"font-weight: bold;\">Should the landing page be located on a separate resource or on my website?</span>\r\nIt is possible but not necessary. It is important to understand: a landing page in the perception of the Internet user is a separate page with a special offer. It can be physically located on the other side of the world. Or lie literally next to them. In any case, it is one click from your store. But its perception by the visitor - as well as the result - does not change in any way.\r\nThe only caveat: if the landing page is created on a reputable and specialized service with a high rating, then the likelihood of visiting it and triggering increases.

Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, although as of 2019, they are far short of being able to pass the Turing test. Chatbots are typically used in dialog systems for various practical purposes including customer service or information acquisition. Some chatbots use sophisticated natural language processing systems, but many simpler ones scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database.\r\nThe term &quot;ChatterBot&quot; was originally coined by Michael Mauldin (creator of the first Verbot, Julia) in 1994 to describe these conversational programs. Today, most chatbots are accessed via virtual assistants such as Google Assistant and Amazon Alexa, via messaging apps such as Facebook Messenger or WeChat, or via individual organizations' apps and websites. Chatbots can be classified into usage categories such as conversational commerce (e-commerce via chat), analytics, communication, customer support, design, developer tools, education, entertainment, finance, food, games, health, HR, marketing, news, personal, productivity, shopping, social, sports, travel and utilities.\r\nBeyond chatbots, Conversational AI refers to the use of messaging apps, speech-based assistants and chatbots to automate communication and create personalized customer experiences at scale.\r\nThe process of building, testing and deploying chatbots can be done on cloud-based chatbot development platforms offered by cloud Platform as a Service (PaaS) providers such as Oracle Cloud Platform SnatchBot and IBM Watson. These cloud platforms provide Natural Language Processing, Artificial Intelligence and Mobile Backend as a Service for chatbot development.\r\nSome Companies like Microsoft Azure and AARC are currently providing their Bot Engines through which chatbot Platforms or Software can be developed.","materialsDescription":"New tools designed to simplify the interaction between humans and computers have hit the market: Chatbots or Virtual Assistants. In banking, chatbots and virtual assistants are some of the industry’s newest tools designed to simplify the interaction between humans and computers.\r\n<span style=\"font-weight: bold;\">What is a chatbot?</span>\r\nA chatbot is artificial intelligence (AI) software that can simulate a conversation (or a chat) with a user in natural language through messaging applications, websites, mobile apps or through the telephone.\r\n<span style=\"font-weight: bold;\">Why are chatbots important?</span>\r\nA chatbot is often described as one of the most advanced and promising expressions of interaction between humans and machines. However, from a technological point of view, a chatbot only represents the natural evolution of a Question-Answering system leveraging Natural Language Processing (NLP). Formulating responses to questions in natural language is one of the most typical examples of Natural Language Processing applied in various enterprises’ end-use applications.\r\n<span style=\"font-weight: bold;\">How does a chatbot work?</span>\r\nThere are two different tasks at the core of a chatbot:\r\n<ol><li>user request analysis</li><li>returning the response</li></ol>\r\nUser request analysis: this is the first task that a chatbot performs. It analyzes the user’s request to identify the user intent and to extract relevant entities.\r\nThe ability to identify the user’s intent and extract data and relevant entities contained in the user’s request is the first condition and the most relevant step at the core of a chatbot: If you are not able to correctly understand the user’s request, you won’t be able to provide the correct answer.\r\nReturning the response: once the user’s intent has been identified, the chatbot must provide the most appropriate response for the user’s request. The answer may be:\r\n<ul><li>a generic and predefined text;</li><li>a text retrieved from a knowledge base that contains different answers;</li><li>a contextualized piece of information based on data the user has provided;</li><li>data stored in enterprise systems;</li><li>the result of an action that the chatbot performed by interacting with one or more backend application;</li><li>a disambiguating question that helps the chatbot to correctly understand the user’s request.</li></ul>\r\n<span style=\"font-weight: bold;\">In what is the benefit of chatbots?</span>\r\nChatbot applications streamline interactions between people and services, enhancing the customer experience. At the same time, they offer companies new opportunities to improve the customer's engagement process and operational efficiency by reducing the typical cost of customer service.\r\nTo be successful, a chatbot solution should be able to effectively perform both of these tasks. Human support plays a key role here: Regardless of the kind of approach and the platform, human intervention is crucial in configuring, training and optimizing the chatbot system.\r\n<span style=\"font-weight: bold;\">Which chatbot application is right for you?</span>\r\nThere are different approaches and tools that you can use to develop a chatbot. Depending on the use case you want to address, some chatbot technologies are more appropriate than others.

Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.\r\nSoftware can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open-source software), or for personal use (e.g. a scientist may write software to automate a mundane task). Embedded software development, that is, the development of embedded software, such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself and is often developed separately.\r\nThe need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.\r\nThere are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development.","materialsDescription":" <span style=\"font-weight: bold; \">What is software development?</span>\r\nSoftware itself is the set of instructions or programs that tell a computer what to do. It is independent of hardware and makes computers programmable. There are three basic types:\r\n<span style=\"font-weight: bold; \">System software</span> to provide core functions such as operating systems, disk management, utilities, hardware management, and other operational necessities.\r\n<span style=\"font-weight: bold; \">Programming software</span> to give programmers tools such as text editors, compilers, linkers, debuggers and other tools to create code.\r\n<span style=\"font-weight: bold; \">Application software</span> (applications or apps) to help users perform tasks. Office productivity suites, data management software, media players and security programs are examples. Applications also refer to web and mobile applications like those used to shop on Amazon.com, socialize with Facebook or post pictures to Instagram.\r\nA possible fourth type is <span style=\"font-weight: bold; \">embedded software.</span> Embedded systems software is used to control machines and devices not typically considered computers — telecommunications networks, cars, industrial robots and more. These devices, and their software, can be connected as part of the Internet of Things (IoT).\r\nSoftware development is primarily conducted by programmers, software engineers, and software developers. These roles interact and overlap, and the dynamics between them vary greatly across development departments and communities.\r\n<span style=\"font-weight: bold; \">Programmers, or coders,</span> write source code to program computers for specific tasks like merging databases, processing online orders, routing communications, conducting searches or displaying text and graphics. Programmers typically interpret instructions from software developers and engineers and use programming languages like C++ or Java to carry them out.\r\n<span style=\"font-weight: bold; \">Software engineers</span> apply engineering principles to build software and systems to solve problems. They use modeling language and other tools to devise solutions that can often be applied to problems in a general way, as opposed to merely solving for a specific instance or client. Software engineering solutions adhere to the scientific method and must work in the real world, as with bridges or elevators.\r\n<span style=\"font-weight: bold; \">Software developers</span> have a less formal role than engineers and can be closely involved with specific project areas — including writing code. At the same time, they drive the overall software development lifecycle — including working across functional teams to transform requirements into features, managing development teams and processes, and conducting software testing and maintenance.\r\nThe work of software development isn’t confined to coders or development teams. Professionals such as scientists, device fabricators, and hardware makers also create software code even though they are not primarily software developers. Nor is it confined to traditional information technology industries such as software or semiconductor businesses. In fact, according to the Brookings Institute, those businesses “account for less than half of the companies performing software development.”\r\nAn important distinction is custom software development as opposed to commercial software development. Custom software development is the process of designing, creating, deploying and maintaining software for a specific set of users, functions or organizations. In contrast, commercial off-the-shelf software (COTS) is designed for a broad set of requirements, allowing it to be packaged and commercially marketed and distributed.\r\n<span style=\"font-weight: bold;\">Steps in the software development process</span>\r\nDeveloping software typically involves the following steps:\r\n<ul><li><span style=\"font-weight: bold;\">Selecting a methodology</span> to establish a framework in which the steps of software development are applied. It describes an overall work process or roadmap for the project. Methodologies can include Agile development, DevOps, Rapid Application Development (RAD), Scaled Agile Framework (SAFe), Waterfall and others.</li><li><span style=\"font-weight: bold;\">Gathering requirements</span> to understand and document what is required by users and other stakeholders.</li><li><span style=\"font-weight: bold;\">Choosing or building architecture</span> as the underlying structure within which the software will operate.</li><li><span style=\"font-weight: bold;\">Developing a design</span> around solutions to the problems presented by requirements, often involving process models and storyboards.</li><li><span style=\"font-weight: bold;\">Constructing code</span> in the appropriate programming language. Involves peer and team review to eliminate problems early and produce quality software faster.</li><li><span style=\"font-weight: bold;\">Testing</span> with pre-planned scenarios as part of software design and coding — and conducting performance testing to simulate load testing on the application.</li><li><span style=\"font-weight: bold;\">Managing configuration and defects</span> to understand all the software artifacts (requirements, design, code, test) and build distinct versions of the software. Establish quality assurance priorities and release criteria to address and track defects.</li><li><span style=\"font-weight: bold;\">Deploying</span> the software for use and responding to and resolving user problems.</li><li><span style=\"font-weight: bold;\">Migrating data</span> to the new or updated software from existing applications or data sources if necessary.</li><li><span style=\"font-weight: bold;\">Managing and measuring the project</span> to maintain quality and delivery over the application lifecycle, and to evaluate the development process with models such as the Capability Maturity Model (CMM).</li></ul>\r\nThe steps of the software development process fit into application lifecycle management.\r\n<ul><li>Requirements analysis and specification</li><li>Design and development</li><li>Testing</li><li>Deployment</li><li>Maintenance and support</li></ul>\r\nSoftware development process steps can be grouped into the phases of the lifecycle, but the importance of the lifecycle is that it recycles to enable continuous improvement. For example, user issues that surface in the maintenance and support phase can become requirements at the beginning of the next cycle.\r\n<span style=\"font-weight: bold;\">Why is software development important?</span>\r\nSoftware development is important because it helps businesses differentiate themselves and be more competitive. It can improve customer experiences, bring more innovative, feature-rich products to market faster, and make operations more efficient, safe and productive.\r\nSoftware development is also important because it is pervasive.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Development.png"},{"id":615,"title":"Web Development","alias":"web-development","description":" Web development is the work involved in developing a website for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing a simple single static page of plain text to complex web-based internet applications (web apps), electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering, web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development.\r\nAmong web professionals, &quot;web development&quot; usually refers to the main non-design aspects of building websites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills.\r\nFor larger organizations and businesses, web development teams can consist of hundreds of people (web developers) and follow standard methods like Agile methodologies while developing websites. Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designer or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. There are three kinds of web developer specialization: front-end developer, back-end developer, and full-stack developer. Front-end developers are responsible for behavior and visuals that run in the user browser, while back-end developers deal with the servers.\r\nSince the commercialization of the web, web development has been a growing industry. The growth of this industry is being driven by businesses wishing to use their website to advertise and sell products and services to customers.\r\nThere are many open source tools for web development such as BerkeleyDB, GlassFish, LAMP (Linux, Apache, MySQL, PHP) stack and Perl/Plack. This has kept the cost of learning web development to a minimum. Another contributing factor to the growth of the industry has been the rise of easy-to-use WYSIWYG web-development software, such as Adobe Dreamweaver, BlueGriffon and Microsoft Visual Studio. Knowledge of HyperText Markup Language (HTML) or of programming languages is still required to use such software, but the basics can be learned and implemented quickly.\r\nAn ever-growing set of tools and technologies have helped developers build more dynamic and interactive websites. Further, web developers now help to deliver applications as web services which were traditionally only available as applications on a desk-based computer. This has allowed for many opportunities to decentralize information and media distribution. Examples can be seen with the rise of cloud services such as Adobe Creative Cloud, Dropbox and Google Drive. These web services allow users to interact with applications from many locations, instead of being tied to a specific workstation for their application environment.\r\nExamples of dramatic transformation in communication and commerce led by web development include e-commerce. Online auction sites such as eBay have changed the way consumers find and purchase goods and services. Online retailers such as Amazon.com and Buy.com (among many others) have transformed the shopping and bargain-hunting experience for many consumers. Another example of transformative communication led by web development is the blog. Web applications such as WordPress and Movable Type have created blog-environments for individual websites. The increased usage of open-source content management systems and enterprise content management systems has extended web development's impact at online interaction and communication.\r\nWeb development has also impacted personal networking and marketing. Websites are no longer simply tools for work or for commerce, but serve more broadly for communication and social networking. Web sites such as Facebook and Twitter provide users with a platform to communicate and organizations with a more personal and interactive way to engage the public.","materialsDescription":" <span style=\"font-weight: bold; \">What is the Priority of a Web Developer?</span>\r\nTo answer the question “What is a web developer?”, we must first look at what a web developer does and how they do it.\r\nA web developer or programmer is someone who takes a web design – which has been created by either a client or a design team – and turns it into a website. They do this by writing lines and lines of complicated code, using a variety of languages. Web developers have quite a difficult job, because they essentially have to take a language we understand, such as English, and translate it into a language that a computer understands, such as Python or HTML.\r\nAs you can imagine, this can take a lot of time and effort and requires an intricate understanding of various programming languages and how they are used. Different types of developers specialize in different areas, which means that large web projects are usually a collaboration between several different developers.\r\n<span style=\"font-weight: bold; \">What Types Of Web Developers Are There?</span>\r\nUnfortunately, the question “What does a web developer do?” doesn’t have one simple answer. As noted above, there are some different types of web developers, each of which focuses on a different aspect of the creation of a website.\r\nTo understand what is a web developer it is crucial to know that the three main types of developers are front-end, back-end, and full-stack. Front-end developers are responsible for the parts of a website that people see and interact with, back-end developers are responsible for the behind the scenes code that controls how a website loads and runs, and full-stack developers do a bit of everything.\r\n<span style=\"font-weight: bold; \">Front-End Developer</span>\r\nA front-end developer is someone who takes a client or design team’s website design and writes the code needed to implement it on the web. A decent front-end web developer will be fluent in at least three programming languages – HTML, CSS, and JavaScript.\r\nHTML allows them to add content to a website while splitting it into headings, paragraphs, and tables. CSS lets a decent developer style the content and change things like colors, sizes, and borders. JavaScript allows the inclusion of interactive elements, such as push buttons. We will go into more detail about these languages later.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">So, what do web developers do when they work on the front end of a website?</span></span>\r\n<ul><li>What is a web developer responsible for is that they make sure that all of the content that is needed for the website is clear, visible, and found in the right place. In some cases front-end developers may also have content writing skills, allowing them to create the content for the website as they go.</li><li>They make sure that the right colors are in the right places, especially concerning text colors, background colors, and headers. Some of the best front-end developers are also very good designers, allowing them to tweak things as they go.</li><li>They make sure that all outbound links are correctly formatted, that all buttons work properly, and that the website is responsive and attractive. Mobile design is usually a big part of the job, while it is also important to make sure that a website will display correctly on all web browsers.</li></ul>\r\n<span style=\"font-weight: bold;\">Back-End Developer</span>\r\nWhile it may seem like front-end developers have a difficult job making sure that a website looks great, works well, and contains the correct content, back-end developers have it much worse. While front-end developers are responsible for client-side programming, back-end developers have to deal with the server-side.\r\nThis means that they have to create the code and programs which power the website’s server, databases, and any applications that it contains. The most important thing as a back-end developer is the ability to be able to create a clean, efficient code that does what you want it to in the quickest way possible. Since website speed is a major consideration when it comes to search engine optimization (SEO), it is a large factor when developing the back-end.\r\nTo fully explain what is a web developer it is essential to know that back-end developers use a wide range of different server-side languages to build complicated programs. Some of the most popular languages used include PHP, Python, Java, and Ruby. JavaScript is also becoming increasingly widespread as a back-end development language, while SQL is commonly used to manage and analyze data in website databases.\r\nSince different websites have different needs, a back-end developer must be flexible, able to create different programs, and they absolutely must have a clear, in-depth understanding of the languages that they use. This is very important to make sure that they can come up with the most efficient method of creating the required program while making sure that it is secure, scalable, and easy to maintain.\r\n<span style=\"font-weight: bold;\">Full-Stack Developer</span>\r\nIf you are looking for a quick, simple answer to the question “What is a web developer?”, then a full-stack developer is probably the closest thing that you’re going to get. Full-stack developers understand both front and back-end strategies and processes, which means that they are perfectly positioned to oversee the entire process.\r\nIn the case of small websites that don’t have a huge development budget, a full-stack developer will often be employed to build the entire website. In this case, it is extremely important for them to have a complete, in-depth understanding of both front and back-end development and how they work.\r\nLearning full-stack development techniques has a huge range of benefits, including:\r\n<ul><li>You will end up with the knowledge to be able to create an entire website on your own. This makes you a lot more employable, increasing your job security in the future.</li><li>As a full-stack developer, you will understand the connections between the front and back-ends of a website, allowing you do build efficient and effective programs for all parts of the website.</li><li>Full-stack developers are often employed to oversee large projects for big web development companies. Positions like this are likely to be paid more than standard web development positions, making them more attractive to developers. Full-stack defines what is a web developer.</li></ul>\r\nAlthough most developers start with either front or back-end specializations, there are a lot of reasons why you should consider branching out and learning both. It will make you a lot more employable, will give you a greater understanding of the whole concept of what is web development, and will make it easier for you to create entire websites on your own.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Web_Development.png"},{"id":601,"title":"Custom Software Development","alias":"custom-software-development","description":" Custom software (also known as bespoke software or tailor-made software) is software that organization for some specific organization or another user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.\r\nSince custom software is developed for a single customer it can accommodate that customer's particular preferences and expectations. Custom software may be developed in an iterative process, allowing all nuances and possible hidden risks to be taken into account, including issues which were not mentioned in the original requirement specifications (which are, as a rule, never perfect). In particular, the first phase in the software development process may involve many departments, materchode including marketing, engineering, research and development and general management.\r\nLarge companies commonly use custom software for critical functions, including content management, inventory management, customer management, human resource management, or otherwise to fill the gaps present in the existing software packages. Often such software is legacy software, developed before COTS or free software packages offering the required functionality became available.\r\nCustom software development is often considered expensive compared to off-the-shelf solutions or products. This can be true if one is speaking of typical challenges and typical solutions. However, it is not always true. In many cases, COTS software requires customization to correctly support the buyer's operations. The cost and delay of COTS customization can even add up to the expense of developing custom software. Cost is not the only consideration, however, as the decision to opt for custom software often includes the requirement for the purchaser to own the source code, to secure the possibility of future development or modifications to the installed system.\r\nAdditionally, COTS comes with upfront license costs which vary enormously but sometimes run into the millions (in terms of dollars). Furthermore, the big software houses that release COTS products revamp their product very frequently. Thus a particular customization may need to be upgraded for compatibility every two to four years. Given the cost of customization, such upgrades also turn out to be expensive, as a dedicated product release cycle will have to be earmarked for them.\r\nThe decision to build custom software or go for a COTS implementation would usually rest on one or more of the following factors:\r\n<ul><li>Finances - both cost and benefit: The upfront license cost for COTS products mean that a thorough cost-benefit analysis of the business case needs to be done. However it is widely known that large custom software projects cannot fix all three of scope, time/cost and quality constant, so either the cost or the benefits of a custom software project will be subject to some degree of uncertainty - even disregarding the uncertainty around the business benefits of a feature that is successfully implemented.</li><li>Supplier - In the case of COTS, is the supplier likely to remain in business long, and will there be adequate support and customization available? Alternatively, will there be a realistic possibility of getting support and customization from third parties? In the case of custom software, software development may be outsourced or done in-house. If it is outsourced, the question is: is the supplier reputable, and do they have a good track record?</li><li>Time to market: COTS products usually have a quicker time to market</li><li>Size of implementation: COTS comes with standardization of business processes and reporting. For a global or national organization, these can bring in gains in cost savings, efficiency and productivity, if the branch offices are all willing and able to use the same COTS without heavy customizations (which is not always a given).</li></ul>","materialsDescription":" <span style=\"font-weight: bold;\">Why is custom software such a large investment?</span>\r\nBuilding a custom web application is a time-consuming endeavor. It takes time to learn the processes of your business, to gather requirements, to flesh out your needs, and to build the software. Put simply, time is money.\r\nWhile it’s a large investment, by investing in custom software, you’ll own the code instead of having a long-term licensing agreement with another software company.\r\n<span style=\"font-weight: bold;\">How could my business benefit from custom software?</span>\r\nA custom business software solution increases process efficiency through process automation. When business processes are properly automated, they minimize the waste in time and resources that the original processes contained.\r\nThink of it this way: with software that already exists, you have to modify your process to meet software capabilities. With custom software, you can build a system around the existing processes you have in place. You took a lot of time to develop those processes, so why should you revamp your business?\r\n<span style=\"font-weight: bold;\">What is IP and how important is it that I own it?</span>\r\nIP stands for Intellectual Property. When you deal with anything creative, you have to think about copyright and the intellectual property on that work and that includes the creation of software code.\r\nThis gets back to the question of buying vs. building. If there is an existing solution that can suit your needs just fine, then it makes sense to buy, but the software developer owns the code and you are basically licensing the software from there. However, if you need a specialized solution that is customized to your needs and decide to go the custom development route, then the question of who owns the code is an important one.\r\n<span style=\"font-weight: bold;\">I’m thinking about hiring someone offshore; what should I watch out for?</span>\r\nIn short, everything. Language barriers and lack of proximity lead to breakdowns in communication and quality. Do yourself a favor and stay local.\r\nOn a related note, if you’re thinking about hiring for the position internally, think about this: it takes around three people to complete a successful custom software project. If you hire someone internally, their salary might cost what it would take to build with us, and you get a whole team when you work with us. Plus, if your software developer decides to leave, they take their knowledge with them. If one of our team members leave, our whole team shares the knowledge so you’re not left in the dark.\r\n<span style=\"font-weight: bold;\">If things don’t go well, am I sunk?</span>\r\nWe make communication and transparency are top priorities so this doesn’t happen. Right out of the gate we work hard to make sure that not only the project is a good fit, but the relationship with the client is as well. Through each step of the process and the build, we keep you in the loop weekly so you know what to expect and what is happening, but a good development company should have places in their process/relationship where you can cleanly exit. Make sure you know what the process is for leaving and what those different ‘leaving’ options are.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Custom_Software_Development.png"},{"id":597,"title":"Android Software Application","alias":"android-software-application","description":" Android software development is the process by which new applications are created for devices running the Android operating system. Google states that &quot;Android apps can be written using Kotlin, Java, and C++ languages&quot; using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some languages/programming tools allow cross-platform app support, i.e. for both Android and iOS. Third party tools, development environments and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, Bank of America etc. eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.\r\nAndroid was created by the Open Handset Alliance, which is led by Google. The early feedback on developing applications for the Android platform was mixed. Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. In December 2007, MergeLab mobile startup founder Adam MacBeth stated, &quot;Functionality is not there, is poorly documented or just doesn't work... It's clearly not ready for prime time.&quot; Despite this, Android-targeted applications began to appear the week after the platform was announced. The first publicly available application was the Snake game.\r\nA preview release of the Android SDK was released on November 12, 2007. On July 15, 2008, the Android Developer Challenge Team accidentally sent an email to all entrants in the Android Developer Challenge announcing that a new release of the SDK was available in a &quot;private&quot; download area. The email was intended for winners of the first round of the Android Developer Challenge. The revelation that Google was supplying new SDK releases to some developers and not others (and keeping this arrangement private) led to widely reported frustration within the Android developer community at the time.\r\nOn August 18, 2008, the Android 0.9 SDK beta was released. This release provided an updated and extended API, improved development tools and an updated design for the home screen. Detailed instructions for upgrading are available to those already working with an earlier release. On September 23, 2008, the Android 1.0 SDK (Release 1) was released. According to the release notes, it included &quot;mainly bug fixes, although some smaller features were added.&quot; It also included several API changes from the 0.9 version. Multiple versions have been released since it was developed.\r\nOn December 5, 2008, Google announced the first Android Dev Phone, a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. It was a modified version of HTC's Dream phone. While developers can use regular consumer devices to test and use their applications, some developers may choose a dedicated unlocked or no-contract device.\r\nAs of July 2013, more than one million applications have been developed for Android, with over 25 billion downloads. A June 2011 research indicated that over 67% of mobile developers used the platform, at the time of publication. Android smartphone shipments are forecast to exceed 1.2 billion units in 2018 with an 85% market share.","materialsDescription":" <span style=\"font-weight: bold;\">Where does Android come from?</span>\r\nIt comes from Google, who actually acquired Android in 2005 (no, Google didn't invent it). The search giant performs regular updates along with an annual major update.\r\nThe operating system is based on the Linux kernel – if you have friends who work in IT, you may have heard of it. This is the GNU / Linux operating system based structure, which is a unix type system (portable operating system, multitasking and multi-user). The Linux kernel is one of the most prominent examples of free software.\r\n<span style=\"font-weight: bold;\">Why does Android look different on each phone?</span>\r\nAndroid doesn't look different on every device, but it does have a number of different versions. Android is open-source, which means that manufacturers are free to customize the software and make it their own.\r\nThe 'purest' version of Android is often referred to as 'stock Android' and it's often preferred by the Android community: it's the original software as Google intended.\r\nOther user interfaces (UI) include Samsung's TouchWiz, Sony's Xperia, and Huawei's Emotion. See what they all look like in our Android UI comparison.\r\n<span style=\"font-weight: bold;\">What are the advantages of Android?</span>\r\nChoice. For example, if you want iOS, you have a choice of iPhone, iPhone or iPhone. If you go for Android there are stacks of great devices to choose from, from cheap and cheerful handsets to really impressive flagships. Those flagships are often cheaper than the equivalent Apple devices, too.\r\nAndroid’s choice isn’t just about hardware. It’s about everything else too. Android is incredibly easy to customize, both in terms of how it looks and how it works, and the various app stores aren’t as tightly controlled as its rivals’ stores, like Apple.\r\n<span style=\"font-weight: bold;\">What’s with the candy names?</span>\r\nEach new version of Android gets a code name based on consecutive letters of the alphabet. The most recent version is known as Marshmallow because it is the Android M release. Previous versions have included Lollipop, KitKat, Jelly Bean and Gingerbread.\r\n<span style=\"font-weight: bold;\">What’s the best thing about Android?</span>\r\nOptions, many options. With Android, you have hundreds of gadgets at your disposal, the cheapest, the most expensive and innovative market. Android is also incredibly customizable, both in their roles, as in his appearance. You can really make a unique mobile experience for yourself with this OS.\r\n<span style=\"font-weight: bold;\">What’s the worst thing about Android?</span>\r\nGetting updates. In many cases, manufacturers don’t seem to care about providing software updates for devices they’ve already sold you. Even when they do provide updates they take their sweet time about it. That’s why some consider rooting: you can download the updates yourself and apply them instead of waiting for the manufacturer to get around to it.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Android_Software_Application.png"},{"id":595,"title":"iOS Software Development","alias":"ios-software-development","description":"iOS is Apple’s mobile OS that runs on an iPhone, iPad, iPod Touch hardware.

These applications can be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing (e.g., JavaScript) to provide an &quot;application-like&quot; experience within a Web browser. Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms. Mobile app development has been steadily growing, in revenues and jobs created. A 2013 analyst report estimates there are 529,000 direct app economy jobs within the EU 28 members, 60% of which are mobile app developers.\r\nAs part of the development process, mobile user interface (UI) design is also essential in the creation of mobile apps. Mobile UI considers constraints, contexts, screen, input, and mobility as outlines for design. The user is often the focus of interaction with their device, and the interface entails components of both hardware and software. User input allows for the users to manipulate a system, and device's output allows the system to indicate the effects of the users' manipulation. Mobile UI design constraints include limited attention and form factors, such as a mobile device's screen size for a user's hand(s). Mobile UI contexts signal cues from user activity, such as location and scheduling that can be shown from user interactions within a mobile app. Overall, mobile UI design's goal is mainly for an understandable, user-friendly interface. The UI of mobile apps should: consider users' limited attention, minimize keystrokes, and be task-oriented with a minimum set of functions. This functionality is supported by mobile enterprise application platforms or integrated development environments (IDEs).\r\nMobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems. The mobile back-end facilitates data routing, security, authentication, authorization, working off-line, and service orchestration. This functionality is supported by a mix of middleware components including mobile app server, mobile backend as a service (MBaaS), and service-oriented architecture (SOA) infrastructure. ","materialsDescription":" <span style=\"font-weight: bold;\">What is the native app development?</span>\r\nUnlike websites and web applications, native mobile apps don’t run in the browser. You need to download them from platform-specific app stores such as Apple’s App Store and Google Play. After installation, you can access each app by tapping its respective icon on the screen of your device.\r\nNative app development requires different skills and technologies than mobile website development. You don’t have to worry about browser behavior and compatibility. You can use the native features of mobile OSs to deliver the user experience and implement the functionalities of your app.\r\n<span style=\"font-weight: bold;\">What is the difference between a native mobile app and a hybrid app?</span>\r\nMobile apps have two types: native and hybrid apps. At first glance, both have similar features and design but the underlying technology is different. As the name suggests, hybrid apps are a combination of web apps and native mobile apps. You can build them using web technologies: HTML, CSS, and JavaScript. You can also upload them to app stores and users can install them as native Android or iOS applications.\r\nThe main advantages of hybrid apps are portability and the simplicity of development. You only have to write the code once and your hybrid app will run on different operating systems. You can use hybrid frameworks like Ionic and Apache Cordova to create cross-platform hybrid applications. By contrast, native mobile apps have to be written in platform-specific languages such as Java, Swift, or Objective-C.\r\nNative mobile apps can access the built-in features of smartphones such as the camera and microphone by default. If you have a hybrid app you need to rely on plugins like Cordova plugins to use the native capabilities of the user’s device.\r\nHybrid apps also depend on WebViews to render their user interfaces. WebViews are in-app browsers that allow mobile applications to access and display web content. This is how Android and iOS devices are able to run hybrid apps built with HTML, CSS, and JavaScript as native mobile applications.\r\n<span style=\"font-weight: bold;\">What are the benefits of native mobile app development?</span>\r\nAlthough hybrid apps are easier and cheaper to develop, native mobile apps have many benefits, too.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better performance</span></span>\r\nNative mobile apps directly interact with native APIs without depending on middleware such as plugins and WebViews. As there are fewer dependencies, native mobile apps are faster and more responsive than hybrid apps. This is especially important for performance-centric apps like games and graphic-heavy applications.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Consistent look and feel</span></span>\r\nAs native mobile apps are developed using native SDKs (software development kits), their UIs look consistent with their platform. This ensures a better user experience, as there are no discrepancies between the OS and app design.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Immediate access to new features</span></span>\r\nNative mobile apps can immediately access the latest iOS or Android features. As web technologies can’t directly use native APIs, hybrid apps have to wait until there’s a plugin that supports the new feature.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better compliance with app store guidelines</span></span>\r\nBecause of their architecture, native mobile apps comply better with app store guidelines. In 2017, Apple restricted its submission guidelines. Since then, they have begun to reject apps that rely too much on WebViews, such as Ionic View that allowed developers to test their Ionic applications. As it’s likely that app stores will continue cracking down on hybrid apps, native mobile apps are also a more future-proof investment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Mobile_Software_Development.png"},{"id":611,"title":"ObjectiveC Development","alias":"objectivec-development","description":"Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for the macOS, iOS and iPadOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch until the introduction of Swift in 2014.\r\nThe language was originally developed in the early 1980s. It was later selected as the main language used by NeXT for its NeXTSTEP operating system, from which macOS and iOS are derived. Portable Objective-C programs that do not use Apple libraries, or those using parts that may be ported or reimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang.\r\nObjective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension.\r\nObjective-C was invented in the early 1980s as a means to add Object-Oriented programming capabilities to C. The inventors, Brad Cox and Tom Love, thought that Smalltalk (an early OO language) could provide the tools needed for truly re-usable code and for creating development environments for systems developers.\r\nCox began by writing a pre-processor for C that allowed for the inclusion of Smalltalk-like code, which would then be rendered into compilable C. This turned into a fully-Object-Oriented C extension.\r\nObjective-C was eventually fully defined and described in the book Object-Oriented Programming: An Evolutionary Approach.\r\nNeXT licensed Objective-C in 1988 and developed several tools based on it. These tools eventually became (after several intermediate steps) the Cocoa development environment, which is used by several Apple systems: Mac OS X, iOS, Apple WatchOS.\r\nFor several years now, apps are written for one of these Apple operating systems needed to be written (or compiled to, or run on top of) Objective-C.

And why is it different from other CMS?</span>\r\nThere are many reasons why Drupal is the top three most used CMS, and why tons of small to big complex systems have made it their options. Here are those:\r\n<ul><li><span style=\"font-weight: bold;\">Reliability.</span> Drupal is one of the top three most popular content management systems in the world. It has a longstanding history. Though Drupal is a work in progress, it has been stable along the way. We have Drupal 7 now while Drupal 8 is going to be released. But you can be assured that you will be supported for Drupal previous version at least 5 years. Meanwhile, the resources will stay there for goods.</li><li><span style=\"font-weight: bold;\">Available resources.</span> Nearly anything you want to do with the system has been priorly created and done absolutely well by other people. Other great news is nearly all of the most useful modules (Drupal add-ons) are contributed to the Drupal community. This is invaluable because, in many CMS, you have to pay for important features. As a user, you have benefited greatly from someone’s efforts, and experience.</li><li><span style=\"font-weight: bold;\">A huge dedicated community.</span> The Drupal community is large, dynamic and has functioned well since 2001. As a newbie or a senior developer, Drupal.org is a must-have resource where you dig in for learning material, upcoming news, or ask for support from contributors, and specialists.</li><li><span style=\"font-weight: bold;\">Robust and convenience.</span> Be assured that the source code for building your Drupal sites has been precisely written, and designed by Drupal experts. When you have an intention to do more complex and advanced work, you will find it easy and convenient to modify the system. This grants users a great advantage over other CMS.</li><li><span style=\"font-weight: bold;\">Flexibility.</span> It’s not a chance that Drupal is considered the most flexible CMS. We have always thought that if you have an idea about any functions, contents, you can certainly create it with Drupal. Seriously. You can create any content on site. You can customize anything to fit your taste. You can create any website type that you want.</li><li><span style=\"font-weight: bold;\">Scalability.</span> By scalability, we mean that you can extend your Drupal core to a higher level with a variety of contributed Drupal modules. What’s great with the Drupal modules is that they integrate perfectly well with Drupal core. They also connect absolutely efficiently with the modules. This is regardless of the fact many modules are totally different. It is due to the natural structure &amp; built-in system of Drupal. This thereby enhances the power of extending your Drupal website. It is also a core strength of Drupal compared with other CMS. Meanwhile, Drupal is an open source. So suppose the modules you want don’t exist, you can create one, edit an existing module, or hire someone to do the job.</li><li><span style=\"font-weight: bold;\">Security.</span> Drupal has been meticulously tested up to strict security rules by Drupal experts and contributors. Its built-in security is strong. Drupal will lock down whatever directory installed, rendering important data, configuration files unable to be accessed directly. No wonder that many big sites with extreme security are using Drupal, namely - whitehouse.org, commerce.gov, weforum.org,...</li></ul>\r\n<span style=\"font-weight: bold;\">What are the uses of Drupal?</span>\r\nAs stated, due to its flexibility and extensibility, Drupal is not limited to any kind. Browse these lists to see the wide range of things that Drupal can build:\r\n<ul><li>Personal or corporate Web sites</li><li>Community portal sites</li><li>Intranet/Corporate sites</li><li>Blogs, art, portfolio, music, multimedia sites</li><li>Forums</li><li>International sites (websites with multi languages)</li><li>E-commerce sites</li><li>Resource directories</li><li>Social networking sites</li></ul>\r\n<span style=\"font-weight: bold;\">When Drupal isn't right?</span>\r\nIf it is necessary to know about a system before we set our foot on, it’s never been less important to explore its cons. Here we bring some of our caveats for the system:\r\n<ul><li>There’s a little learning curve. You will not learn and work with Drupal in a few days. Accept this fact. It’s harder to start compared with other CMS like Wordpress. But once you learn some basic things, it’s easy, and the flow is smoother.</li><li>It is not for those who have insufficient time to educate themselves about this system, or little money to pay a Drupal developer to carry out the work.</li><li>Finding a good Drupal developer is harder to find than that of Wordpress or other systems. It’s not hard to guess this considering the number of Wordpress developers compared with Drupal.</li></ul>\r\nIt always takes some investments to learn about something. For a new user, it would be a huge opportunity cost - what you will gain and lose working with one system and leave others behind.\r\nBut after all the choice is always yours.We expect it would be worth. The CMS you will spend thousands hours working. The system through this you make a living. The option that yields energy and satisfaction.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Drupal_Development__1_.png"},{"id":621,"title":"WordPress","alias":"wordpress","description":"","materialsDescription":"","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WordPress.png"},{"id":623,"title":"Magento Development","alias":"magento-development","description":" Magento is an open-source e-commerce platform written in PHP.

It was originally created by Rasmus Lerdorf in 1994; the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor.\r\nPHP code may be executed with a command line interface (CLI), embedded into HTML code, or used in combination with various web template systems, web content management systems, and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in a web server or as a Common Gateway Interface (CGI) executable. The web server outputs the results of the interpreted and executed PHP code, which may be any type of data, such as generated HTML code or binary image data. PHP can be used for many programming tasks outside of the web context, such as standalone graphical applications and robotic drone control.\r\nThe standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.\r\nThe PHP language evolved without a written formal specification or standard until 2014, with the original implementation acting as the de facto standard which other implementations aimed to follow. Since 2014, work has gone on to create a formal PHP specification.\r\nAs of September 2019, over 60% of sites on the web using PHP are still on discontinued/&quot;EOLed&quot; version 5.6 or older; versions prior to 7.2 are no longer officially supported by The PHP Development Team, but security support is provided by third parties, such as Debian.","materialsDescription":" <span style=\"font-weight: bold; \">What is PHP?</span>\r\nPHP stands for Hypertext Preprocessor.

Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.\r\nRuby on Rails' emergence in the 2000s greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Python, Catalyst in Perl, Laravel and CakePHP in PHP, Phoenix in Elixir, Play in Scala, and Sails.js in Node.js.\r\nRuby on Rails is intended to emphasize Convention over Configuration (CoC), and the Don't Repeat Yourself (DRY) principle.\r\n&quot;Convention over Configuration&quot; means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table &quot;products sold&quot;, that the developer needs to write code regarding these names. Generally, Ruby on Rails conventions lead to less code and less repetition.\r\n&quot;Don't repeat yourself&quot; means that information is located in a single, unambiguous place. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions. Instead, Ruby on Rails can retrieve this information from the database based on the class name.\r\n&quot;Fat models, skinny controllers&quot; means that most of the application logic should be placed within the model while leaving the controller as light as possible.","materialsDescription":" <span style=\"font-weight: bold;\">What is Ruby on Rails?</span>\r\nRails is a development tool that gives web developers a framework, providing structure for all the code they write. The Rails framework helps developers to build websites and applications because it abstracts and simplifies common repetitive tasks.\r\nRails are written in Ruby, the programming language which is also used alongside Rails. Ruby is to Rails as PHP is to Symfony and Zend, or as Python is to Django. The appeal of Ruby to developers lies in the elegance and terseness of the language.\r\nOne of the key principles of Ruby on Rails development (henceforth ‘Rails’) is convention over configuration. This means that the programmer does not have to spend a lot of time configuring files in order to get set up, Rails comes with a set of conventions which help speed up development.\r\nAnother characteristic of Rails is the emphasis on RESTful application design. REST (Representational State Transfer) is a style of software architecture based around the client-server relationship. It encourages a logical structure within applications, which means they can easily be exposed as an API (Application Programming Interface).\r\nFrom a project management point of view, the Ruby on Rails community advocate Agile web development – an iterative development method, that encourages collaborative and flexible approach, which is particularly well-suited for web application development with fast-changing requirements.\r\nOver the last few years Ruby on Rails has gained a large and enthusiastic following, but let’s consider the main arguments for and against Rails.\r\n<span style=\"font-weight: bold;\">Why is it necessary to use Ruby on Rails?</span>\r\n<ul><li>The process of programming is much faster than with other frameworks and languages, partly because of the object-oriented nature of Ruby and the vast collection of open source code available within the Rails community.</li><li>The Rails conventions also make it easy for developers to move between different Rails projects, as each project will tend to follow the same structure and coding practices.</li><li>Rails are good for rapid application development (RAD), as the framework makes it easy to accommodate changes.</li><li>Ruby code is very readable and mostly self-documenting.

Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.\r\nPython is dynamically typed and garbage-collected. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Python is often described as a &quot;batteries included&quot; language due to its comprehensive standard library.\r\nPython was conceived in the late 1980s as a successor to the ABC language. Python 2.0, released in 2000, introduced features like list comprehensions and a garbage collection system capable of collecting reference cycles. Python 3.0, released in 2008, was a major revision of the language that is not completely backward-compatible, and much Python 2 code does not run unmodified on Python 3.\r\nThe Python 2 language, i.e. Python 2.7.x, was officially discontinued on 1 January 2020 (first planned for 2015) after which security patches and other improvements will not be released for it.

Object-oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming and metaobjects (magic methods)). Many other paradigms are supported via extensions, including design by contract and logic programming.\r\nPython uses dynamic typing and a combination of reference counting and a cycle-detecting garbage collector for memory management. It also features dynamic name resolution (late binding), which binds method and variable names during program execution.\r\nPython's design offers some support for functional programming in the Lisp tradition. It has filter, map, and reduce functions; list comprehensions, dictionaries, sets, and generator expressions.

Consider the design options, payment gateways, the security of the site, integration with other tools, features and pricing before finalizing on the platform.\r\n<span style=\"font-weight: bold;\">How should I promote my eСommerce site?</span>\r\nThere are various ways to do this and the first thing to do is to promote the site to all the customers. This will help to increase your customer base. Your website address should be present in every advertisement that your company invests in. Register with the search engines and optimize your website as this will affect the traffic of your site.\r\n<span style=\"font-weight: bold;\">What are the important things that can turn browsers into buyers?</span>\r\nCreate your site so that it is much more oriented towards sales rather than marketing. Let your visitors see your products immediately instead of hiding them behind lots of marketing copy. Make a page that reads the terms and conditions as it will offer a professional look. Provide your contact details and explain your return policies, security, encryption methods, and payment options.\r\n<span style=\"font-weight: bold;\">How to create an impressive website?</span>\r\nThe beauty of a site lies in the way it operates and how user-friendly it is.&nbsp; Ensure that your site is fast, easy to use, professional and attractive. Also, make sure that you are able to fulfill the orders very promptly without any delay. In case you are unable to offer the service, make sure that your customer is informed about it via email.\r\n<span style=\"font-weight: bold;\">What are the security risks that are involved with eСommerce sites?</span>\r\neCommerce website owners should always keep in mind the three dimensions of security - confidentiality, integrity, and availability. Business owners should develop a good strategy that can help to make the site and transactions secured. To avoid any hackers gain access to important confidential data, include encryption methods for any data transactions.\r\n<span style=\"font-weight: bold;\">Is there any limit on the size of my product or customer database?</span>\r\nNo, as such there are no limits on the size. The biggest benefit of having an online store is that you can add unlimited products and catalogs and at the same time you can grow your customer base as you require.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_eCommerce_development.png"},{"id":639,"title":"HTML Development","alias":"html-development","description":" Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.\r\nWeb browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.\r\nHTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as &lt;img /&gt; and &lt;input /&gt; directly introduce content into the page. Other tags such as &lt;p&gt; surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.\r\nHTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.","materialsDescription":" <span style=\"font-weight: bold;\">What is HTML5?</span>\r\nHTML5 contains powerful capabilities for Web-based applications with more powerful interaction, video support, graphics, more styling effects, and a full set of APIs. HTML5 adapts to any device, whether desktop, mobile, tablet, or television. HTML5 is an open platform developed under royalty-free licensing terms.\r\nPeople use the term HTML5 in two ways:\r\n<ul><li>to refer to a set of technologies that together form the future Open Web Platform. These technologies include HTML5 specification, CSS3, SVG, MathML, Geolocation, XmlHttpRequest, Context 2D, Web Fonts (WOFF) and others. The boundary of this set of technologies is informal and changes over time;</li><li>to refer to the HTML5 specification, which is, of course, also part of the Open Web Platform.</li></ul>\r\nAlthough it would be great if people used one term to refer to the specification and another term to refer to a set of specifications, in practice people use the term both ways.\r\n<span style=\"font-weight: bold;\">HTML5 has been cited by many thought leaders as the future of the Web. Why is HTML5 generating this excitement?</span>\r\nThere is huge demand for open standards that allow the creation of rich internet applications. Watching videos, finding the nearest restaurant, accessing emails while being offline are just some of the powerful new capabilities enabled by the set of specifications in development at W3C.\r\nOne aspect that interests W3C, in particular, is enabling people to combine different technologies. W3C works to ensure not just interoperable support in the software of a single specification, but compatibility among specifications.\r\nEven though HTML5 is still a draft, browser vendors are deploying features and generating a lot of excitement in the IT industry. This experience, in turn, allows W3C to revise its drafts. In this way, the final standard can transparently inform implementers where they need to pay close attention to security and privacy issues.\r\n<span style=\"font-weight: bold;\">When can I use HTML5?</span>\r\nPeople can already use parts of the platform that interoperate, but W3C's mission is global interoperable, to ensure that the web is available to all. Not all elements are fully implemented yet and some of them provide builtin fallback mechanisms, such as &lt;video&gt; or &lt;input&gt;. One can use HTML5 today, knowing the existing limitations and ensuring proper fallbacks.\r\n<span style=\"font-weight: bold;\">Which Web Browsers support HTML5?</span>\r\nW3C encourages implementation and testing long before a specification becomes a standard to ensure that two people can read a specification independently and write interoperable software. Early adopters provide implementers and W3C with tremendously valuable feedback because they help identify where interoperability issues exist.\r\n<span style=\"font-weight: bold;\">Do you think that the benefits of HTML5, such as its neutrality, rich graphics, no need plug-ins, outweigh the security risk it carries?</span>\r\nNow entering its third decade, the Web has evolved from a Web of documents into a formidable platform for networked applications that let us share information and services over the Internet. In this highly connected environment, it is important that powerful Web applications be designed with sensitivity to user privacy and security needs. The risks associated with modern Web applications are familiar to the HTML5 community.\r\nHTML5 and related specifications are being developed in W3C's open standards process. This process allows an expert review of features along with their security and privacy implications. Rich functionality that was previously available only through proprietary plugins is now documented in an open specification for all experts to review and improve. We're pleased to see the HTML5 specifications subject to rigorous public review since that helps make the Web a more secure environment.\r\nSome security issues are not confined to HTML5. W3C and IETF are working closely to specify technologies and protocol extensions to mitigate some issues (such as cross-site request forgery and cross-site scripting).\r\n<span style=\"font-weight: bold;\">Will there be an HTML6?</span>\r\nNo work is currently happening on HTML6 but feature requests that are not planned to be addressed in HTML5 are available at listed under HTML.next.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_HTML_Development.png"},{"id":667,"title":"Database Development","alias":"database-development","description":" Database development is the process of creating a database and setting its integrity parameters.

The effort is undertaken by a developer, ranging from a single person to an international team dispersed across the globe. Development of traditional commercial PC and console games is normally funded by a publisher, and can take several years to reach completion. Indie games usually take less time and money and can be produced by individuals and smaller developers. The independent game industry has been on the rise, facilitated by the growth of accessible game development software such as Unity platform and Unreal Engine and new online distribution systems such as Steam and Uplay, as well as the mobile game market for Android and iOS devices.\r\nThe first video games, developed in the 1960s, were noncommercial. They required mainframe computers to run and were not available to the general public. Commercial game development began in the '70s with the advent of first-generation video game consoles and early home computers like the Apple I. At that time, owing to low costs and low capabilities of computers, a lone programmer could develop a full and complete game. However, in the late '80s and '90s, ever-increasing computer processing power and heightened expectations from gamers made it difficult for a single person to produce a mainstream console or PC game. The average cost of producing a triple-A video game slowly rose, from US$1–4 million in 2000, to over $5 million in 2006, then to over $20 million by 2010.\r\nMainstream commercial PC and console games are generally developed in phases: first, in pre-production, pitches, prototypes, and game design documents are written; if the idea is approved and the developer receives funding, then full-scale development begins. The development of a complete game usually involves a team of 20–100 individuals with various responsibilities, including designers, artists, programmers, and testers.\r\nThe game revenue from retails is divided among the parties along the distribution chain, such as — developer, publisher, retail, manufacturer and console royalty. Many developers fail to profit from this and go bankrupt. Many developers seek alternative economic models through Internet marketing and distribution channels to improve returns., as through a mobile distribution channel the share of a developer can be up to 70% of the total revenue and through an online distribution channel almost 100%.","materialsDescription":" <span style=\"font-weight: bold;\">How important are games?</span>\r\nThe popularity of smart gadgets like smartphones, tablets etc have opened up a new avenue of entertainment in the software industry and that is the domain of the mobile gaming sector.

Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, although as of 2019, they are far short of being able to pass the Turing test. Chatbots are typically used in dialog systems for various practical purposes including customer service or information acquisition. Some chatbots use sophisticated natural language processing systems, but many simpler ones scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database.\r\nThe term &quot;ChatterBot&quot; was originally coined by Michael Mauldin (creator of the first Verbot, Julia) in 1994 to describe these conversational programs. Today, most chatbots are accessed via virtual assistants such as Google Assistant and Amazon Alexa, via messaging apps such as Facebook Messenger or WeChat, or via individual organizations' apps and websites. Chatbots can be classified into usage categories such as conversational commerce (e-commerce via chat), analytics, communication, customer support, design, developer tools, education, entertainment, finance, food, games, health, HR, marketing, news, personal, productivity, shopping, social, sports, travel and utilities.\r\nBeyond chatbots, Conversational AI refers to the use of messaging apps, speech-based assistants and chatbots to automate communication and create personalized customer experiences at scale.\r\nThe process of building, testing and deploying chatbots can be done on cloud-based chatbot development platforms offered by cloud Platform as a Service (PaaS) providers such as Oracle Cloud Platform SnatchBot and IBM Watson.

In banking, chatbots and virtual assistants are some of the industry’s newest tools designed to simplify the interaction between humans and computers.\r\n<span style=\"font-weight: bold;\">What is a chatbot?</span>\r\nA chatbot is artificial intelligence (AI) software that can simulate a conversation (or a chat) with a user in natural language through messaging applications, websites, mobile apps or through the telephone.\r\n<span style=\"font-weight: bold;\">Why are chatbots important?</span>\r\nA chatbot is often described as one of the most advanced and promising expressions of interaction between humans and machines. However, from a technological point of view, a chatbot only represents the natural evolution of a Question-Answering system leveraging Natural Language Processing (NLP). Formulating responses to questions in natural language is one of the most typical examples of Natural Language Processing applied in various enterprises’ end-use applications.\r\n<span style=\"font-weight: bold;\">How does a chatbot work?</span>\r\nThere are two different tasks at the core of a chatbot:\r\n<ol><li>user request analysis</li><li>returning the response</li></ol>\r\nUser request analysis: this is the first task that a chatbot performs. It analyzes the user’s request to identify the user intent and to extract relevant entities.\r\nThe ability to identify the user’s intent and extract data and relevant entities contained in the user’s request is the first condition and the most relevant step at the core of a chatbot: If you are not able to correctly understand the user’s request, you won’t be able to provide the correct answer.\r\nReturning the response: once the user’s intent has been identified, the chatbot must provide the most appropriate response for the user’s request. The answer may be:\r\n<ul><li>a generic and predefined text;</li><li>a text retrieved from a knowledge base that contains different answers;</li><li>a contextualized piece of information based on data the user has provided;</li><li>data stored in enterprise systems;</li><li>the result of an action that the chatbot performed by interacting with one or more backend application;</li><li>a disambiguating question that helps the chatbot to correctly understand the user’s request.</li></ul>\r\n<span style=\"font-weight: bold;\">In what is the benefit of chatbots?</span>\r\nChatbot applications streamline interactions between people and services, enhancing the customer experience. At the same time, they offer companies new opportunities to improve the customer's engagement process and operational efficiency by reducing the typical cost of customer service.\r\nTo be successful, a chatbot solution should be able to effectively perform both of these tasks. Human support plays a key role here: Regardless of the kind of approach and the platform, human intervention is crucial in configuring, training and optimizing the chatbot system.\r\n<span style=\"font-weight: bold;\">Which chatbot application is right for you?</span>\r\nThere are different approaches and tools that you can use to develop a chatbot.

The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals (user-centered design).\r\nGood user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design and typography are utilized to support its usability, influencing how the user performs certain interactions and improving the aesthetic appeal of the design; design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs.\r\nInterface design is involved in a wide range of projects from computer systems, to cars, to commercial planes; all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge. As a result, designers tend to specialize in certain types of projects and have skills centered on their expertise, whether it is a software design, user research, web design, or industrial design.","materialsDescription":" <span style=\"font-weight: bold;\">What is a Graphical User Interface?</span>\r\nThe graphical user interface, developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple’s Macintosh and Microsoft’s Windows operating systems, was designed as a response to the problem of inefficient usability in early, text-based command-line interfaces for the average user.\r\nGraphical user interfaces would become the standard of user-centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bars, windows, tabs, menus, cursors, and the mouse pointing device. Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities.\r\n<span style=\"font-weight: bold;\">How Does a Graphical User Interface Work?</span>\r\nGraphical user interface design principles conform to the model–view–controller software pattern, which separates internal representations of information from the manner in which information is presented to the user, resulting in a platform where users are shown which functions are possible rather than requiring the input of command codes. Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task.\r\nThe appearance, or “skin,” of an operating system or application software may be redesigned at will due to the nature of graphical user interfaces being independent from application functions. Applications typically implement their own unique graphical user interface display elements in addition to graphical user interface elements already present on the existing operating system. A typical graphical user interface also includes standard formats for representing graphics and text, making it possible to share data between applications running under common graphical user interface design software.\r\nGraphical user interface testing refers to the systematic process of generating test cases in order to evaluate the functionality of the system and its design elements. Graphical user interface testing tools, which are either manual or automated and typically implemented by third-party operators, are available under a variety of licenses and are supported by a variety of platforms. Popular examples include: Tricentis Tosca, Squish GUI Tester, Unified Functional Testing (UFT), Maveryx, Appium, and eggPlant Functional.\r\n<span style=\"font-weight: bold;\">Graphical User Interface Examples</span>\r\nSketchpad, believed to be the first graphical computer-aided design program, was developed in 1962 by Ivan Sutherland while he was at MIT, and consisted of a light pen that enabled users to create and manipulate objects in engineering drawings in real-time with coordinated graphics.\r\nModern operating systems and graphical user interfaces are incorporated into nearly every interactive application, such as ATMs, self-service checkouts, airline self-ticketing and check-in, video games, smartphones, and desktops. Some popular, modern graphical user interface examples include Microsoft Windows, macOS, Ubuntu Unity, and GNOME Shell for desktop environments, and Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS, and Firefox OS for smartphones.\r\n<span style=\"font-weight: bold;\">Advantages of Graphical User Interfaces</span>\r\nThe advantage of a graphical user interface is a stark improvement in useability for the average person. The features of a graphical user interface leverage familiar metaphors, such as drag-and-drop for transferring files, and use familiar icons, such as a trash bin for deleted files, creating an environment in which computer operations are intuitive and easily mastered without any prior practice or knowledge of computing machinery or languages. Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_User_Interface_Development.png"},{"id":655,"title":"Perl Development","alias":"perl-development","description":" Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. &quot;Perl&quot; refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned &quot;sister language&quot;, Perl 6, before the latter's name was officially changed to Raku in October 2019.\r\nThough Perl is not officially an acronym, there are various backronyms in use, including &quot;Practical Extraction and Reporting Language&quot;. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another.\r\nThe Perl languages borrow features from other programming languages including C, shell script (sh), AWK, and sed; Wall also alludes to BASIC and Lisp in the introduction to Learning Perl (Schwartz &amp; Christiansen) and so on. They provide text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools, facilitating manipulation of text files. Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its unsurpassed regular expression and string parsing abilities.\r\nIn addition to CGI, Perl 5 is used for system administration, network programming, finance, bioinformatics, and other applications, such as for GUIs. It has been nicknamed &quot;the Swiss Army chainsaw of scripting languages&quot; because of its flexibility and power, and also its ugliness. In 1998, it was also referred to as the &quot;duct tape that holds the Internet together,&quot; in reference to both its ubiquitous use as a glue language and its perceived inelegance.\r\nAccording to Wall, Perl has two slogans. The first is &quot;There's more than one way to do it,&quot; commonly known as TMTOWTDI. The second slogan is &quot;Easy things should be easy and hard things should be possible&quot;.\r\nThe overall structure of Perl derives broadly from C. Perl is procedural in nature, with variables, expressions, assignment statements, brace-delimited blocks, control structures, and subroutines.\r\nPerl also takes features from shell programming. All variables are marked with leading sigils, which allow variables to be interpolated directly into strings. However, unlike the shell, Perl uses sigils on all accesses to variables, and unlike most other programming languages that use sigils, the sigil doesn't denote the type of the variable but the type of the expression. So for example, to access a list of values in a hash, the sigil for an array (&quot;@&quot;) is used, not the sigil for a hash (&quot;%&quot;). Perl also has many built-in functions that provide tools often used in shell programming (although many of these tools are implemented by programs external to the shell) such as sorting, and calling operating system facilities.\r\nPerl takes lists from Lisp, hashes (&quot;associative arrays&quot;) from AWK, and regular expressions from sed. These simplify and facilitate many parsing, text-handling, and data-management tasks. Also shared with Lisp are the implicit return of the last value in a block, and the fact that all statements have a value, and thus are also expressions and can be used in larger expressions themselves.\r\nAll versions of Perl do automatic data-typing and automatic memory management. The interpreter knows the type and storage requirements of every data object in the program; it allocates and frees storage for them as necessary using reference counting (so it cannot deallocate circular data structures without manual intervention). Legal type conversions — for example, conversions from number to string — are done automatically at run time; illegal type conversions are fatal errors.","materialsDescription":" <span style=\"font-weight: bold;\">What is Perl?</span>\r\n<ul><li>Perl is a stable, cross-platform programming language.</li><li>Though Perl is not officially an acronym few people used it as <span style=\"font-weight: bold;\">Practical Extraction and Report Language</span>.</li><li>It is used for mission-critical projects in the public and private sectors.</li><li>Perl is an Open Source software, licensed under its Artistic License, or the <span style=\"font-style: italic;\">GNU General Public License (GPL)</span>.</li><li>Perl was created by Larry Wall.</li><li>Perl 1.0 was released to Usenet's alt.comp.sources in 1987.</li><li>Perl is listed in the Oxford English Dictionary.</li></ul>\r\n<span style=\"font-weight: bold;\">What are the features of Perl programming?</span>\r\n<ul><li>Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others.</li><li>Perl's database integration interface DBI supports third-party databases including Oracle, Sybase, Postgres, MySQL, and others.</li><li>Perl works with HTML, XML, and other mark-up languages.</li><li>Perl supports Unicode.</li><li>Perl is Y2K compliant.</li><li>Perl supports both procedural and object-oriented programming.</li><li>Perl interfaces with external C/C++ libraries through XS or SWIG.</li><li>Perl is extensible.

QA focuses on improving the processes to deliver Quality Products to the customer. An organization has to ensure, that processes are efficient and effective as per the quality standards defined for software products. Quality Assurance is popularly known as <span style=\"font-weight: bold; \">QA Testing. </span>\r\nQA establishes and maintains set requirements for developing or manufacturing reliable products. A quality assurance system is meant to increase customer confidence and a company's credibility, while also improving work processes and efficiency, and it enables a company to better compete with others.\r\nQuality assurance helps a company create products and services that meet the needs, expectations and requirements of customers. It yields high-quality product offerings that build trust and loyalty with customers. The standards and procedures defined by a quality assurance program help prevent product defects before they arise.\r\n<span style=\"font-weight: bold; \">Quality assurance utilizes one of three methods:</span>\r\n<span style=\"font-weight: bold; \">Failure testing, </span>which continually tests a product to determine if it breaks or fails. For physical products that need to withstand stress, this could involve testing the product under heat, pressure or vibration. For software products, failure testing might involve placing the software under high usage or load conditions.\r\n<span style=\"font-weight: bold; \">Statistical process control (SPC),</span> a methodology based on objective data and analysis and developed by Walter Shewhart at Western Electric Company and Bell Telephone Laboratories in the 1920's and 1930's. This methodology uses statistical methods to manage and control the production of products.\r\n<span style=\"font-weight: bold; \">Total quality management (TQM),</span> which applies quantitative methods as the basis for continuous improvement. TQM relies on facts, data and analysis to support product planning and performance reviews.\r\n<span style=\"font-weight: bold; \">Quality assurance in software.</span> Software quality assurance&nbsp; management (SQA) systematically finds patterns and the actions needed to improve development cycles. Finding and fixing coding errors can carry unintended consequences; it is possible to fix one thing, yet break other features and functionality at the same time.\r\nSQA software has become important for developers as a means of avoiding errors before they occur, saving development time and expenses. Even with SQA processes in place, an update to software can break other features and cause defects - commonly known as bugs.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> Differences between Software testing and SQA services</h1>\r\n<ul><li><span style=\"font-weight: bold; \">SQA tools</span></li></ul>\r\n- Is about engineering process that ensures quality\r\n- Involve activities related to the implementation of processes, procedures, and standards.\r\n- Process focused \r\n- Preventive technique\r\n- Proactive measure\r\n- The scope of software quality testing tools applied to all products that will be created by the organization\r\n<ul><li><span style=\"font-weight: bold; \">Software Testing</span></li></ul>\r\n- Software Testing is to test a product for problems before the product goes live\r\n- Involves actives concerning verification of product Example - Review Testing\r\n- Product focused\r\n - Corrective technique\r\n- Reactive measure\r\n- The scope of Software Testing applies to a particular product being tested\r\n<h1 class=\"align-center\">Manual QA testing services Vs Automated Quality Assurance Testing</h1>\r\nSoftware testing is a huge domain, but it can be broadly categorized into two areas: manual testing and automated testing.

Each testing type – manual and automated – comes with its own set of advantages and disadvantages. \r\nYou can choose between manual and quality assurance testing services based on a variety of factors.

Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.\r\nSoftware can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open-source software), or for personal use (e.g. a scientist may write software to automate a mundane task). Embedded software development, that is, the development of embedded software, such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself and is often developed separately.\r\nThe need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.\r\nThere are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development.","materialsDescription":" <span style=\"font-weight: bold; \">What is software development?</span>\r\nSoftware itself is the set of instructions or programs that tell a computer what to do. It is independent of hardware and makes computers programmable. There are three basic types:\r\n<span style=\"font-weight: bold; \">System software</span> to provide core functions such as operating systems, disk management, utilities, hardware management, and other operational necessities.\r\n<span style=\"font-weight: bold; \">Programming software</span> to give programmers tools such as text editors, compilers, linkers, debuggers and other tools to create code.\r\n<span style=\"font-weight: bold; \">Application software</span> (applications or apps) to help users perform tasks. Office productivity suites, data management software, media players and security programs are examples. Applications also refer to web and mobile applications like those used to shop on Amazon.com, socialize with Facebook or post pictures to Instagram.\r\nA possible fourth type is <span style=\"font-weight: bold; \">embedded software.</span> Embedded systems software is used to control machines and devices not typically considered computers — telecommunications networks, cars, industrial robots and more. These devices, and their software, can be connected as part of the Internet of Things (IoT).\r\nSoftware development is primarily conducted by programmers, software engineers, and software developers. These roles interact and overlap, and the dynamics between them vary greatly across development departments and communities.\r\n<span style=\"font-weight: bold; \">Programmers, or coders,</span> write source code to program computers for specific tasks like merging databases, processing online orders, routing communications, conducting searches or displaying text and graphics. Programmers typically interpret instructions from software developers and engineers and use programming languages like C++ or Java to carry them out.\r\n<span style=\"font-weight: bold; \">Software engineers</span> apply engineering principles to build software and systems to solve problems. They use modeling language and other tools to devise solutions that can often be applied to problems in a general way, as opposed to merely solving for a specific instance or client. Software engineering solutions adhere to the scientific method and must work in the real world, as with bridges or elevators.\r\n<span style=\"font-weight: bold; \">Software developers</span> have a less formal role than engineers and can be closely involved with specific project areas — including writing code. At the same time, they drive the overall software development lifecycle — including working across functional teams to transform requirements into features, managing development teams and processes, and conducting software testing and maintenance.\r\nThe work of software development isn’t confined to coders or development teams. Professionals such as scientists, device fabricators, and hardware makers also create software code even though they are not primarily software developers. Nor is it confined to traditional information technology industries such as software or semiconductor businesses. In fact, according to the Brookings Institute, those businesses “account for less than half of the companies performing software development.”\r\nAn important distinction is custom software development as opposed to commercial software development. Custom software development is the process of designing, creating, deploying and maintaining software for a specific set of users, functions or organizations. In contrast, commercial off-the-shelf software (COTS) is designed for a broad set of requirements, allowing it to be packaged and commercially marketed and distributed.\r\n<span style=\"font-weight: bold;\">Steps in the software development process</span>\r\nDeveloping software typically involves the following steps:\r\n<ul><li><span style=\"font-weight: bold;\">Selecting a methodology</span> to establish a framework in which the steps of software development are applied. It describes an overall work process or roadmap for the project. Methodologies can include Agile development, DevOps, Rapid Application Development (RAD), Scaled Agile Framework (SAFe), Waterfall and others.</li><li><span style=\"font-weight: bold;\">Gathering requirements</span> to understand and document what is required by users and other stakeholders.</li><li><span style=\"font-weight: bold;\">Choosing or building architecture</span> as the underlying structure within which the software will operate.</li><li><span style=\"font-weight: bold;\">Developing a design</span> around solutions to the problems presented by requirements, often involving process models and storyboards.</li><li><span style=\"font-weight: bold;\">Constructing code</span> in the appropriate programming language. Involves peer and team review to eliminate problems early and produce quality software faster.</li><li><span style=\"font-weight: bold;\">Testing</span> with pre-planned scenarios as part of software design and coding — and conducting performance testing to simulate load testing on the application.</li><li><span style=\"font-weight: bold;\">Managing configuration and defects</span> to understand all the software artifacts (requirements, design, code, test) and build distinct versions of the software. Establish quality assurance priorities and release criteria to address and track defects.</li><li><span style=\"font-weight: bold;\">Deploying</span> the software for use and responding to and resolving user problems.</li><li><span style=\"font-weight: bold;\">Migrating data</span> to the new or updated software from existing applications or data sources if necessary.</li><li><span style=\"font-weight: bold;\">Managing and measuring the project</span> to maintain quality and delivery over the application lifecycle, and to evaluate the development process with models such as the Capability Maturity Model (CMM).</li></ul>\r\nThe steps of the software development process fit into application lifecycle management.\r\n<ul><li>Requirements analysis and specification</li><li>Design and development</li><li>Testing</li><li>Deployment</li><li>Maintenance and support</li></ul>\r\nSoftware development process steps can be grouped into the phases of the lifecycle, but the importance of the lifecycle is that it recycles to enable continuous improvement. For example, user issues that surface in the maintenance and support phase can become requirements at the beginning of the next cycle.\r\n<span style=\"font-weight: bold;\">Why is software development important?</span>\r\nSoftware development is important because it helps businesses differentiate themselves and be more competitive. It can improve customer experiences, bring more innovative, feature-rich products to market faster, and make operations more efficient, safe and productive.\r\nSoftware development is also important because it is pervasive.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Development.png"},{"id":615,"title":"Web Development","alias":"web-development","description":" Web development is the work involved in developing a website for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing a simple single static page of plain text to complex web-based internet applications (web apps), electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering, web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development.\r\nAmong web professionals, &quot;web development&quot; usually refers to the main non-design aspects of building websites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills.\r\nFor larger organizations and businesses, web development teams can consist of hundreds of people (web developers) and follow standard methods like Agile methodologies while developing websites. Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designer or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. There are three kinds of web developer specialization: front-end developer, back-end developer, and full-stack developer. Front-end developers are responsible for behavior and visuals that run in the user browser, while back-end developers deal with the servers.\r\nSince the commercialization of the web, web development has been a growing industry. The growth of this industry is being driven by businesses wishing to use their website to advertise and sell products and services to customers.\r\nThere are many open source tools for web development such as BerkeleyDB, GlassFish, LAMP (Linux, Apache, MySQL, PHP) stack and Perl/Plack. This has kept the cost of learning web development to a minimum. Another contributing factor to the growth of the industry has been the rise of easy-to-use WYSIWYG web-development software, such as Adobe Dreamweaver, BlueGriffon and Microsoft Visual Studio. Knowledge of HyperText Markup Language (HTML) or of programming languages is still required to use such software, but the basics can be learned and implemented quickly.\r\nAn ever-growing set of tools and technologies have helped developers build more dynamic and interactive websites. Further, web developers now help to deliver applications as web services which were traditionally only available as applications on a desk-based computer. This has allowed for many opportunities to decentralize information and media distribution. Examples can be seen with the rise of cloud services such as Adobe Creative Cloud, Dropbox and Google Drive. These web services allow users to interact with applications from many locations, instead of being tied to a specific workstation for their application environment.\r\nExamples of dramatic transformation in communication and commerce led by web development include e-commerce. Online auction sites such as eBay have changed the way consumers find and purchase goods and services. Online retailers such as Amazon.com and Buy.com (among many others) have transformed the shopping and bargain-hunting experience for many consumers. Another example of transformative communication led by web development is the blog. Web applications such as WordPress and Movable Type have created blog-environments for individual websites. The increased usage of open-source content management systems and enterprise content management systems has extended web development's impact at online interaction and communication.\r\nWeb development has also impacted personal networking and marketing. Websites are no longer simply tools for work or for commerce, but serve more broadly for communication and social networking. Web sites such as Facebook and Twitter provide users with a platform to communicate and organizations with a more personal and interactive way to engage the public.","materialsDescription":" <span style=\"font-weight: bold; \">What is the Priority of a Web Developer?</span>\r\nTo answer the question “What is a web developer?”, we must first look at what a web developer does and how they do it.\r\nA web developer or programmer is someone who takes a web design – which has been created by either a client or a design team – and turns it into a website. They do this by writing lines and lines of complicated code, using a variety of languages. Web developers have quite a difficult job, because they essentially have to take a language we understand, such as English, and translate it into a language that a computer understands, such as Python or HTML.\r\nAs you can imagine, this can take a lot of time and effort and requires an intricate understanding of various programming languages and how they are used. Different types of developers specialize in different areas, which means that large web projects are usually a collaboration between several different developers.\r\n<span style=\"font-weight: bold; \">What Types Of Web Developers Are There?</span>\r\nUnfortunately, the question “What does a web developer do?” doesn’t have one simple answer. As noted above, there are some different types of web developers, each of which focuses on a different aspect of the creation of a website.\r\nTo understand what is a web developer it is crucial to know that the three main types of developers are front-end, back-end, and full-stack. Front-end developers are responsible for the parts of a website that people see and interact with, back-end developers are responsible for the behind the scenes code that controls how a website loads and runs, and full-stack developers do a bit of everything.\r\n<span style=\"font-weight: bold; \">Front-End Developer</span>\r\nA front-end developer is someone who takes a client or design team’s website design and writes the code needed to implement it on the web. A decent front-end web developer will be fluent in at least three programming languages – HTML, CSS, and JavaScript.\r\nHTML allows them to add content to a website while splitting it into headings, paragraphs, and tables. CSS lets a decent developer style the content and change things like colors, sizes, and borders. JavaScript allows the inclusion of interactive elements, such as push buttons. We will go into more detail about these languages later.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">So, what do web developers do when they work on the front end of a website?</span></span>\r\n<ul><li>What is a web developer responsible for is that they make sure that all of the content that is needed for the website is clear, visible, and found in the right place. In some cases front-end developers may also have content writing skills, allowing them to create the content for the website as they go.</li><li>They make sure that the right colors are in the right places, especially concerning text colors, background colors, and headers. Some of the best front-end developers are also very good designers, allowing them to tweak things as they go.</li><li>They make sure that all outbound links are correctly formatted, that all buttons work properly, and that the website is responsive and attractive. Mobile design is usually a big part of the job, while it is also important to make sure that a website will display correctly on all web browsers.</li></ul>\r\n<span style=\"font-weight: bold;\">Back-End Developer</span>\r\nWhile it may seem like front-end developers have a difficult job making sure that a website looks great, works well, and contains the correct content, back-end developers have it much worse. While front-end developers are responsible for client-side programming, back-end developers have to deal with the server-side.\r\nThis means that they have to create the code and programs which power the website’s server, databases, and any applications that it contains. The most important thing as a back-end developer is the ability to be able to create a clean, efficient code that does what you want it to in the quickest way possible. Since website speed is a major consideration when it comes to search engine optimization (SEO), it is a large factor when developing the back-end.\r\nTo fully explain what is a web developer it is essential to know that back-end developers use a wide range of different server-side languages to build complicated programs. Some of the most popular languages used include PHP, Python, Java, and Ruby. JavaScript is also becoming increasingly widespread as a back-end development language, while SQL is commonly used to manage and analyze data in website databases.\r\nSince different websites have different needs, a back-end developer must be flexible, able to create different programs, and they absolutely must have a clear, in-depth understanding of the languages that they use. This is very important to make sure that they can come up with the most efficient method of creating the required program while making sure that it is secure, scalable, and easy to maintain.\r\n<span style=\"font-weight: bold;\">Full-Stack Developer</span>\r\nIf you are looking for a quick, simple answer to the question “What is a web developer?”, then a full-stack developer is probably the closest thing that you’re going to get. Full-stack developers understand both front and back-end strategies and processes, which means that they are perfectly positioned to oversee the entire process.\r\nIn the case of small websites that don’t have a huge development budget, a full-stack developer will often be employed to build the entire website. In this case, it is extremely important for them to have a complete, in-depth understanding of both front and back-end development and how they work.\r\nLearning full-stack development techniques has a huge range of benefits, including:\r\n<ul><li>You will end up with the knowledge to be able to create an entire website on your own. This makes you a lot more employable, increasing your job security in the future.</li><li>As a full-stack developer, you will understand the connections between the front and back-ends of a website, allowing you do build efficient and effective programs for all parts of the website.</li><li>Full-stack developers are often employed to oversee large projects for big web development companies. Positions like this are likely to be paid more than standard web development positions, making them more attractive to developers. Full-stack defines what is a web developer.</li></ul>\r\nAlthough most developers start with either front or back-end specializations, there are a lot of reasons why you should consider branching out and learning both. It will make you a lot more employable, will give you a greater understanding of the whole concept of what is web development, and will make it easier for you to create entire websites on your own.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Web_Development.png"},{"id":601,"title":"Custom Software Development","alias":"custom-software-development","description":" Custom software (also known as bespoke software or tailor-made software) is software that organization for some specific organization or another user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.\r\nSince custom software is developed for a single customer it can accommodate that customer's particular preferences and expectations. Custom software may be developed in an iterative process, allowing all nuances and possible hidden risks to be taken into account, including issues which were not mentioned in the original requirement specifications (which are, as a rule, never perfect). In particular, the first phase in the software development process may involve many departments, materchode including marketing, engineering, research and development and general management.\r\nLarge companies commonly use custom software for critical functions, including content management, inventory management, customer management, human resource management, or otherwise to fill the gaps present in the existing software packages. Often such software is legacy software, developed before COTS or free software packages offering the required functionality became available.\r\nCustom software development is often considered expensive compared to off-the-shelf solutions or products. This can be true if one is speaking of typical challenges and typical solutions. However, it is not always true. In many cases, COTS software requires customization to correctly support the buyer's operations. The cost and delay of COTS customization can even add up to the expense of developing custom software. Cost is not the only consideration, however, as the decision to opt for custom software often includes the requirement for the purchaser to own the source code, to secure the possibility of future development or modifications to the installed system.\r\nAdditionally, COTS comes with upfront license costs which vary enormously but sometimes run into the millions (in terms of dollars). Furthermore, the big software houses that release COTS products revamp their product very frequently. Thus a particular customization may need to be upgraded for compatibility every two to four years. Given the cost of customization, such upgrades also turn out to be expensive, as a dedicated product release cycle will have to be earmarked for them.\r\nThe decision to build custom software or go for a COTS implementation would usually rest on one or more of the following factors:\r\n<ul><li>Finances - both cost and benefit: The upfront license cost for COTS products mean that a thorough cost-benefit analysis of the business case needs to be done. However it is widely known that large custom software projects cannot fix all three of scope, time/cost and quality constant, so either the cost or the benefits of a custom software project will be subject to some degree of uncertainty - even disregarding the uncertainty around the business benefits of a feature that is successfully implemented.</li><li>Supplier - In the case of COTS, is the supplier likely to remain in business long, and will there be adequate support and customization available? Alternatively, will there be a realistic possibility of getting support and customization from third parties? In the case of custom software, software development may be outsourced or done in-house. If it is outsourced, the question is: is the supplier reputable, and do they have a good track record?</li><li>Time to market: COTS products usually have a quicker time to market</li><li>Size of implementation: COTS comes with standardization of business processes and reporting. For a global or national organization, these can bring in gains in cost savings, efficiency and productivity, if the branch offices are all willing and able to use the same COTS without heavy customizations (which is not always a given).</li></ul>","materialsDescription":" <span style=\"font-weight: bold;\">Why is custom software such a large investment?</span>\r\nBuilding a custom web application is a time-consuming endeavor. It takes time to learn the processes of your business, to gather requirements, to flesh out your needs, and to build the software. Put simply, time is money.\r\nWhile it’s a large investment, by investing in custom software, you’ll own the code instead of having a long-term licensing agreement with another software company.\r\n<span style=\"font-weight: bold;\">How could my business benefit from custom software?</span>\r\nA custom business software solution increases process efficiency through process automation. When business processes are properly automated, they minimize the waste in time and resources that the original processes contained.\r\nThink of it this way: with software that already exists, you have to modify your process to meet software capabilities. With custom software, you can build a system around the existing processes you have in place. You took a lot of time to develop those processes, so why should you revamp your business?\r\n<span style=\"font-weight: bold;\">What is IP and how important is it that I own it?</span>\r\nIP stands for Intellectual Property. When you deal with anything creative, you have to think about copyright and the intellectual property on that work and that includes the creation of software code.\r\nThis gets back to the question of buying vs. building. If there is an existing solution that can suit your needs just fine, then it makes sense to buy, but the software developer owns the code and you are basically licensing the software from there. However, if you need a specialized solution that is customized to your needs and decide to go the custom development route, then the question of who owns the code is an important one.\r\n<span style=\"font-weight: bold;\">I’m thinking about hiring someone offshore; what should I watch out for?</span>\r\nIn short, everything. Language barriers and lack of proximity lead to breakdowns in communication and quality. Do yourself a favor and stay local.\r\nOn a related note, if you’re thinking about hiring for the position internally, think about this: it takes around three people to complete a successful custom software project. If you hire someone internally, their salary might cost what it would take to build with us, and you get a whole team when you work with us. Plus, if your software developer decides to leave, they take their knowledge with them. If one of our team members leave, our whole team shares the knowledge so you’re not left in the dark.\r\n<span style=\"font-weight: bold;\">If things don’t go well, am I sunk?</span>\r\nWe make communication and transparency are top priorities so this doesn’t happen. Right out of the gate we work hard to make sure that not only the project is a good fit, but the relationship with the client is as well.

Google states that &quot;Android apps can be written using Kotlin, Java, and C++ languages&quot; using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some languages/programming tools allow cross-platform app support, i.e. for both Android and iOS. Third party tools, development environments and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, Bank of America etc. eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.\r\nAndroid was created by the Open Handset Alliance, which is led by Google. The early feedback on developing applications for the Android platform was mixed. Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. In December 2007, MergeLab mobile startup founder Adam MacBeth stated, &quot;Functionality is not there, is poorly documented or just doesn't work... It's clearly not ready for prime time.&quot; Despite this, Android-targeted applications began to appear the week after the platform was announced. The first publicly available application was the Snake game.\r\nA preview release of the Android SDK was released on November 12, 2007. On July 15, 2008, the Android Developer Challenge Team accidentally sent an email to all entrants in the Android Developer Challenge announcing that a new release of the SDK was available in a &quot;private&quot; download area. The email was intended for winners of the first round of the Android Developer Challenge. The revelation that Google was supplying new SDK releases to some developers and not others (and keeping this arrangement private) led to widely reported frustration within the Android developer community at the time.\r\nOn August 18, 2008, the Android 0.9 SDK beta was released. This release provided an updated and extended API, improved development tools and an updated design for the home screen. Detailed instructions for upgrading are available to those already working with an earlier release. On September 23, 2008, the Android 1.0 SDK (Release 1) was released. According to the release notes, it included &quot;mainly bug fixes, although some smaller features were added.&quot; It also included several API changes from the 0.9 version. Multiple versions have been released since it was developed.\r\nOn December 5, 2008, Google announced the first Android Dev Phone, a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. It was a modified version of HTC's Dream phone. While developers can use regular consumer devices to test and use their applications, some developers may choose a dedicated unlocked or no-contract device.\r\nAs of July 2013, more than one million applications have been developed for Android, with over 25 billion downloads. A June 2011 research indicated that over 67% of mobile developers used the platform, at the time of publication. Android smartphone shipments are forecast to exceed 1.2 billion units in 2018 with an 85% market share.","materialsDescription":" <span style=\"font-weight: bold;\">Where does Android come from?</span>\r\nIt comes from Google, who actually acquired Android in 2005 (no, Google didn't invent it). The search giant performs regular updates along with an annual major update.\r\nThe operating system is based on the Linux kernel – if you have friends who work in IT, you may have heard of it. This is the GNU / Linux operating system based structure, which is a unix type system (portable operating system, multitasking and multi-user). The Linux kernel is one of the most prominent examples of free software.\r\n<span style=\"font-weight: bold;\">Why does Android look different on each phone?</span>\r\nAndroid doesn't look different on every device, but it does have a number of different versions. Android is open-source, which means that manufacturers are free to customize the software and make it their own.\r\nThe 'purest' version of Android is often referred to as 'stock Android' and it's often preferred by the Android community: it's the original software as Google intended.\r\nOther user interfaces (UI) include Samsung's TouchWiz, Sony's Xperia, and Huawei's Emotion. See what they all look like in our Android UI comparison.\r\n<span style=\"font-weight: bold;\">What are the advantages of Android?</span>\r\nChoice. For example, if you want iOS, you have a choice of iPhone, iPhone or iPhone. If you go for Android there are stacks of great devices to choose from, from cheap and cheerful handsets to really impressive flagships. Those flagships are often cheaper than the equivalent Apple devices, too.\r\nAndroid’s choice isn’t just about hardware. It’s about everything else too. Android is incredibly easy to customize, both in terms of how it looks and how it works, and the various app stores aren’t as tightly controlled as its rivals’ stores, like Apple.\r\n<span style=\"font-weight: bold;\">What’s with the candy names?</span>\r\nEach new version of Android gets a code name based on consecutive letters of the alphabet. The most recent version is known as Marshmallow because it is the Android M release. Previous versions have included Lollipop, KitKat, Jelly Bean and Gingerbread.\r\n<span style=\"font-weight: bold;\">What’s the best thing about Android?</span>\r\nOptions, many options. With Android, you have hundreds of gadgets at your disposal, the cheapest, the most expensive and innovative market. Android is also incredibly customizable, both in their roles, as in his appearance. You can really make a unique mobile experience for yourself with this OS.\r\n<span style=\"font-weight: bold;\">What’s the worst thing about Android?</span>\r\nGetting updates. In many cases, manufacturers don’t seem to care about providing software updates for devices they’ve already sold you. Even when they do provide updates they take their sweet time about it. That’s why some consider rooting: you can download the updates yourself and apply them instead of waiting for the manufacturer to get around to it.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Android_Software_Application.png"},{"id":595,"title":"iOS Software Development","alias":"ios-software-development","description":"iOS is Apple’s mobile OS that runs on an iPhone, iPad, iPod Touch hardware.

Xcode includes the iOS SDK, tools, compilers, and frameworks you need specifically to design, develop, write code, and debug an app for iOS. For native mobile app development on iOS, Apple suggests using the modern Swift programming language. It is important to note that Xcode only runs on Mac OS X and the only supported way to develop iOS apps.

These applications can be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing (e.g., JavaScript) to provide an &quot;application-like&quot; experience within a Web browser. Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms. Mobile app development has been steadily growing, in revenues and jobs created. A 2013 analyst report estimates there are 529,000 direct app economy jobs within the EU 28 members, 60% of which are mobile app developers.\r\nAs part of the development process, mobile user interface (UI) design is also essential in the creation of mobile apps. Mobile UI considers constraints, contexts, screen, input, and mobility as outlines for design. The user is often the focus of interaction with their device, and the interface entails components of both hardware and software. User input allows for the users to manipulate a system, and device's output allows the system to indicate the effects of the users' manipulation. Mobile UI design constraints include limited attention and form factors, such as a mobile device's screen size for a user's hand(s). Mobile UI contexts signal cues from user activity, such as location and scheduling that can be shown from user interactions within a mobile app. Overall, mobile UI design's goal is mainly for an understandable, user-friendly interface. The UI of mobile apps should: consider users' limited attention, minimize keystrokes, and be task-oriented with a minimum set of functions. This functionality is supported by mobile enterprise application platforms or integrated development environments (IDEs).\r\nMobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems. The mobile back-end facilitates data routing, security, authentication, authorization, working off-line, and service orchestration. This functionality is supported by a mix of middleware components including mobile app server, mobile backend as a service (MBaaS), and service-oriented architecture (SOA) infrastructure. ","materialsDescription":" <span style=\"font-weight: bold;\">What is the native app development?</span>\r\nUnlike websites and web applications, native mobile apps don’t run in the browser. You need to download them from platform-specific app stores such as Apple’s App Store and Google Play. After installation, you can access each app by tapping its respective icon on the screen of your device.\r\nNative app development requires different skills and technologies than mobile website development. You don’t have to worry about browser behavior and compatibility. You can use the native features of mobile OSs to deliver the user experience and implement the functionalities of your app.\r\n<span style=\"font-weight: bold;\">What is the difference between a native mobile app and a hybrid app?</span>\r\nMobile apps have two types: native and hybrid apps. At first glance, both have similar features and design but the underlying technology is different. As the name suggests, hybrid apps are a combination of web apps and native mobile apps. You can build them using web technologies: HTML, CSS, and JavaScript. You can also upload them to app stores and users can install them as native Android or iOS applications.\r\nThe main advantages of hybrid apps are portability and the simplicity of development. You only have to write the code once and your hybrid app will run on different operating systems. You can use hybrid frameworks like Ionic and Apache Cordova to create cross-platform hybrid applications. By contrast, native mobile apps have to be written in platform-specific languages such as Java, Swift, or Objective-C.\r\nNative mobile apps can access the built-in features of smartphones such as the camera and microphone by default. If you have a hybrid app you need to rely on plugins like Cordova plugins to use the native capabilities of the user’s device.\r\nHybrid apps also depend on WebViews to render their user interfaces. WebViews are in-app browsers that allow mobile applications to access and display web content. This is how Android and iOS devices are able to run hybrid apps built with HTML, CSS, and JavaScript as native mobile applications.\r\n<span style=\"font-weight: bold;\">What are the benefits of native mobile app development?</span>\r\nAlthough hybrid apps are easier and cheaper to develop, native mobile apps have many benefits, too.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better performance</span></span>\r\nNative mobile apps directly interact with native APIs without depending on middleware such as plugins and WebViews. As there are fewer dependencies, native mobile apps are faster and more responsive than hybrid apps. This is especially important for performance-centric apps like games and graphic-heavy applications.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Consistent look and feel</span></span>\r\nAs native mobile apps are developed using native SDKs (software development kits), their UIs look consistent with their platform. This ensures a better user experience, as there are no discrepancies between the OS and app design.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Immediate access to new features</span></span>\r\nNative mobile apps can immediately access the latest iOS or Android features. As web technologies can’t directly use native APIs, hybrid apps have to wait until there’s a plugin that supports the new feature.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Better compliance with app store guidelines</span></span>\r\nBecause of their architecture, native mobile apps comply better with app store guidelines. In 2017, Apple restricted its submission guidelines. Since then, they have begun to reject apps that rely too much on WebViews, such as Ionic View that allowed developers to test their Ionic applications. As it’s likely that app stores will continue cracking down on hybrid apps, native mobile apps are also a more future-proof investment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Mobile_Software_Development.png"},{"id":611,"title":"ObjectiveC Development","alias":"objectivec-development","description":"Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for the macOS, iOS and iPadOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch until the introduction of Swift in 2014.\r\nThe language was originally developed in the early 1980s. It was later selected as the main language used by NeXT for its NeXTSTEP operating system, from which macOS and iOS are derived. Portable Objective-C programs that do not use Apple libraries, or those using parts that may be ported or reimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang.\r\nObjective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension.\r\nObjective-C was invented in the early 1980s as a means to add Object-Oriented programming capabilities to C. The inventors, Brad Cox and Tom Love, thought that Smalltalk (an early OO language) could provide the tools needed for truly re-usable code and for creating development environments for systems developers.\r\nCox began by writing a pre-processor for C that allowed for the inclusion of Smalltalk-like code, which would then be rendered into compilable C. This turned into a fully-Object-Oriented C extension.\r\nObjective-C was eventually fully defined and described in the book Object-Oriented Programming: An Evolutionary Approach.\r\nNeXT licensed Objective-C in 1988 and developed several tools based on it. These tools eventually became (after several intermediate steps) the Cocoa development environment, which is used by several Apple systems: Mac OS X, iOS, Apple WatchOS.\r\nFor several years now, apps are written for one of these Apple operating systems needed to be written (or compiled to, or run on top of) Objective-C. That situation is changing now as Apple moves its platform to Swift.\r\nIn addition to Cocoa, Objective-C is also used in the GNUstep platform, which can run on Linux, Unix, BSD, and Windows environment, and which closely mirrors Cocoa.","materialsDescription":" <span style=\"font-weight: bold;\">What is Objective-C?</span>\r\nObjective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.

You can customize anything to fit your taste. You can create any website type that you want.</li><li><span style=\"font-weight: bold;\">Scalability.</span> By scalability, we mean that you can extend your Drupal core to a higher level with a variety of contributed Drupal modules. What’s great with the Drupal modules is that they integrate perfectly well with Drupal core. They also connect absolutely efficiently with the modules. This is regardless of the fact many modules are totally different. It is due to the natural structure &amp; built-in system of Drupal. This thereby enhances the power of extending your Drupal website. It is also a core strength of Drupal compared with other CMS. Meanwhile, Drupal is an open source. So suppose the modules you want don’t exist, you can create one, edit an existing module, or hire someone to do the job.</li><li><span style=\"font-weight: bold;\">Security.</span> Drupal has been meticulously tested up to strict security rules by Drupal experts and contributors. Its built-in security is strong. Drupal will lock down whatever directory installed, rendering important data, configuration files unable to be accessed directly. No wonder that many big sites with extreme security are using Drupal, namely - whitehouse.org, commerce.gov, weforum.org,...</li></ul>\r\n<span style=\"font-weight: bold;\">What are the uses of Drupal?</span>\r\nAs stated, due to its flexibility and extensibility, Drupal is not limited to any kind. Browse these lists to see the wide range of things that Drupal can build:\r\n<ul><li>Personal or corporate Web sites</li><li>Community portal sites</li><li>Intranet/Corporate sites</li><li>Blogs, art, portfolio, music, multimedia sites</li><li>Forums</li><li>International sites (websites with multi languages)</li><li>E-commerce sites</li><li>Resource directories</li><li>Social networking sites</li></ul>\r\n<span style=\"font-weight: bold;\">When Drupal isn't right?</span>\r\nIf it is necessary to know about a system before we set our foot on, it’s never been less important to explore its cons. Here we bring some of our caveats for the system:\r\n<ul><li>There’s a little learning curve. You will not learn and work with Drupal in a few days. Accept this fact. It’s harder to start compared with other CMS like Wordpress. But once you learn some basic things, it’s easy, and the flow is smoother.</li><li>It is not for those who have insufficient time to educate themselves about this system, or little money to pay a Drupal developer to carry out the work.</li><li>Finding a good Drupal developer is harder to find than that of Wordpress or other systems. It’s not hard to guess this considering the number of Wordpress developers compared with Drupal.</li></ul>\r\nIt always takes some investments to learn about something. For a new user, it would be a huge opportunity cost - what you will gain and lose working with one system and leave others behind.\r\nBut after all the choice is always yours.We expect it would be worth. The CMS you will spend thousands hours working. The system through this you make a living. The option that yields energy and satisfaction.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Drupal_Development__1_.png"},{"id":621,"title":"WordPress","alias":"wordpress","description":"","materialsDescription":"","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WordPress.png"},{"id":623,"title":"Magento Development","alias":"magento-development","description":" Magento is an open-source e-commerce platform written in PHP.

It was originally created by Rasmus Lerdorf in 1994; the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor.\r\nPHP code may be executed with a command line interface (CLI), embedded into HTML code, or used in combination with various web template systems, web content management systems, and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in a web server or as a Common Gateway Interface (CGI) executable. The web server outputs the results of the interpreted and executed PHP code, which may be any type of data, such as generated HTML code or binary image data. PHP can be used for many programming tasks outside of the web context, such as standalone graphical applications and robotic drone control.\r\nThe standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.\r\nThe PHP language evolved without a written formal specification or standard until 2014, with the original implementation acting as the de facto standard which other implementations aimed to follow. Since 2014, work has gone on to create a formal PHP specification.\r\nAs of September 2019, over 60% of sites on the web using PHP are still on discontinued/&quot;EOLed&quot; version 5.6 or older; versions prior to 7.2 are no longer officially supported by The PHP Development Team, but security support is provided by third parties, such as Debian.","materialsDescription":" <span style=\"font-weight: bold; \">What is PHP?</span>\r\nPHP stands for Hypertext Preprocessor.

Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.\r\nRuby on Rails' emergence in the 2000s greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Python, Catalyst in Perl, Laravel and CakePHP in PHP, Phoenix in Elixir, Play in Scala, and Sails.js in Node.js.\r\nRuby on Rails is intended to emphasize Convention over Configuration (CoC), and the Don't Repeat Yourself (DRY) principle.\r\n&quot;Convention over Configuration&quot; means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table &quot;products sold&quot;, that the developer needs to write code regarding these names. Generally, Ruby on Rails conventions lead to less code and less repetition.\r\n&quot;Don't repeat yourself&quot; means that information is located in a single, unambiguous place. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions. Instead, Ruby on Rails can retrieve this information from the database based on the class name.\r\n&quot;Fat models, skinny controllers&quot; means that most of the application logic should be placed within the model while leaving the controller as light as possible.","materialsDescription":" <span style=\"font-weight: bold;\">What is Ruby on Rails?</span>\r\nRails is a development tool that gives web developers a framework, providing structure for all the code they write. The Rails framework helps developers to build websites and applications because it abstracts and simplifies common repetitive tasks.\r\nRails are written in Ruby, the programming language which is also used alongside Rails. Ruby is to Rails as PHP is to Symfony and Zend, or as Python is to Django. The appeal of Ruby to developers lies in the elegance and terseness of the language.\r\nOne of the key principles of Ruby on Rails development (henceforth ‘Rails’) is convention over configuration. This means that the programmer does not have to spend a lot of time configuring files in order to get set up, Rails comes with a set of conventions which help speed up development.\r\nAnother characteristic of Rails is the emphasis on RESTful application design. REST (Representational State Transfer) is a style of software architecture based around the client-server relationship. It encourages a logical structure within applications, which means they can easily be exposed as an API (Application Programming Interface).\r\nFrom a project management point of view, the Ruby on Rails community advocate Agile web development – an iterative development method, that encourages collaborative and flexible approach, which is particularly well-suited for web application development with fast-changing requirements.\r\nOver the last few years Ruby on Rails has gained a large and enthusiastic following, but let’s consider the main arguments for and against Rails.\r\n<span style=\"font-weight: bold;\">Why is it necessary to use Ruby on Rails?</span>\r\n<ul><li>The process of programming is much faster than with other frameworks and languages, partly because of the object-oriented nature of Ruby and the vast collection of open source code available within the Rails community.</li><li>The Rails conventions also make it easy for developers to move between different Rails projects, as each project will tend to follow the same structure and coding practices.</li><li>Rails are good for rapid application development (RAD), as the framework makes it easy to accommodate changes.</li><li>Ruby code is very readable and mostly self-documenting.

Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.\r\nPython is dynamically typed and garbage-collected. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Python is often described as a &quot;batteries included&quot; language due to its comprehensive standard library.\r\nPython was conceived in the late 1980s as a successor to the ABC language. Python 2.0, released in 2000, introduced features like list comprehensions and a garbage collection system capable of collecting reference cycles. Python 3.0, released in 2008, was a major revision of the language that is not completely backward-compatible, and much Python 2 code does not run unmodified on Python 3.\r\nThe Python 2 language, i.e. Python 2.7.x, was officially discontinued on 1 January 2020 (first planned for 2015) after which security patches and other improvements will not be released for it. With Python 2's end-of-life, only Python 3.5.x and later are supported.\r\nPython interpreters are available for many operating systems. A global community of programmers develops and maintains CPython, an open source reference implementation. A non-profit organization, the Python Software Foundation, manages and directs resources for Python and CPython development.\r\nPython is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming and metaobjects (magic methods)). Many other paradigms are supported via extensions, including design by contract and logic programming.\r\nPython uses dynamic typing and a combination of reference counting and a cycle-detecting garbage collector for memory management. It also features dynamic name resolution (late binding), which binds method and variable names during program execution.\r\nPython's design offers some support for functional programming in the Lisp tradition. It has filter, map, and reduce functions; list comprehensions, dictionaries, sets, and generator expressions. The standard library has two modules (itertools and functools) that implement functional tools borrowed from Haskell and Standard ML.","materialsDescription":" <span style=\"font-weight: bold;\">What is Python?</span>\r\nPython is an interpreted, interactive, object-oriented programming language.

HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.\r\nHTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as &lt;img /&gt; and &lt;input /&gt; directly introduce content into the page. Other tags such as &lt;p&gt; surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.\r\nHTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages.

Watching videos, finding the nearest restaurant, accessing emails while being offline are just some of the powerful new capabilities enabled by the set of specifications in development at W3C.\r\nOne aspect that interests W3C, in particular, is enabling people to combine different technologies. W3C works to ensure not just interoperable support in the software of a single specification, but compatibility among specifications.\r\nEven though HTML5 is still a draft, browser vendors are deploying features and generating a lot of excitement in the IT industry. This experience, in turn, allows W3C to revise its drafts.

One can use HTML5 today, knowing the existing limitations and ensuring proper fallbacks.\r\n<span style=\"font-weight: bold;\">Which Web Browsers support HTML5?</span>\r\nW3C encourages implementation and testing long before a specification becomes a standard to ensure that two people can read a specification independently and write interoperable software. Early adopters provide implementers and W3C with tremendously valuable feedback because they help identify where interoperability issues exist.\r\n<span style=\"font-weight: bold;\">Do you think that the benefits of HTML5, such as its neutrality, rich graphics, no need plug-ins, outweigh the security risk it carries?</span>\r\nNow entering its third decade, the Web has evolved from a Web of documents into a formidable platform for networked applications that let us share information and services over the Internet. In this highly connected environment, it is important that powerful Web applications be designed with sensitivity to user privacy and security needs. The risks associated with modern Web applications are familiar to the HTML5 community.\r\nHTML5 and related specifications are being developed in W3C's open standards process. This process allows an expert review of features along with their security and privacy implications. Rich functionality that was previously available only through proprietary plugins is now documented in an open specification for all experts to review and improve. We're pleased to see the HTML5 specifications subject to rigorous public review since that helps make the Web a more secure environment.\r\nSome security issues are not confined to HTML5.

The effort is undertaken by a developer, ranging from a single person to an international team dispersed across the globe. Development of traditional commercial PC and console games is normally funded by a publisher, and can take several years to reach completion. Indie games usually take less time and money and can be produced by individuals and smaller developers. The independent game industry has been on the rise, facilitated by the growth of accessible game development software such as Unity platform and Unreal Engine and new online distribution systems such as Steam and Uplay, as well as the mobile game market for Android and iOS devices.\r\nThe first video games, developed in the 1960s, were noncommercial. They required mainframe computers to run and were not available to the general public. Commercial game development began in the '70s with the advent of first-generation video game consoles and early home computers like the Apple I. At that time, owing to low costs and low capabilities of computers, a lone programmer could develop a full and complete game. However, in the late '80s and '90s, ever-increasing computer processing power and heightened expectations from gamers made it difficult for a single person to produce a mainstream console or PC game. The average cost of producing a triple-A video game slowly rose, from US$1–4 million in 2000, to over $5 million in 2006, then to over $20 million by 2010.\r\nMainstream commercial PC and console games are generally developed in phases: first, in pre-production, pitches, prototypes, and game design documents are written; if the idea is approved and the developer receives funding, then full-scale development begins. The development of a complete game usually involves a team of 20–100 individuals with various responsibilities, including designers, artists, programmers, and testers.\r\nThe game revenue from retails is divided among the parties along the distribution chain, such as — developer, publisher, retail, manufacturer and console royalty. Many developers fail to profit from this and go bankrupt. Many developers seek alternative economic models through Internet marketing and distribution channels to improve returns., as through a mobile distribution channel the share of a developer can be up to 70% of the total revenue and through an online distribution channel almost 100%.","materialsDescription":" <span style=\"font-weight: bold;\">How important are games?</span>\r\nThe popularity of smart gadgets like smartphones, tablets etc have opened up a new avenue of entertainment in the software industry and that is the domain of the mobile gaming sector.

Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, although as of 2019, they are far short of being able to pass the Turing test. Chatbots are typically used in dialog systems for various practical purposes including customer service or information acquisition. Some chatbots use sophisticated natural language processing systems, but many simpler ones scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database.\r\nThe term &quot;ChatterBot&quot; was originally coined by Michael Mauldin (creator of the first Verbot, Julia) in 1994 to describe these conversational programs. Today, most chatbots are accessed via virtual assistants such as Google Assistant and Amazon Alexa, via messaging apps such as Facebook Messenger or WeChat, or via individual organizations' apps and websites. Chatbots can be classified into usage categories such as conversational commerce (e-commerce via chat), analytics, communication, customer support, design, developer tools, education, entertainment, finance, food, games, health, HR, marketing, news, personal, productivity, shopping, social, sports, travel and utilities.\r\nBeyond chatbots, Conversational AI refers to the use of messaging apps, speech-based assistants and chatbots to automate communication and create personalized customer experiences at scale.\r\nThe process of building, testing and deploying chatbots can be done on cloud-based chatbot development platforms offered by cloud Platform as a Service (PaaS) providers such as Oracle Cloud Platform SnatchBot and IBM Watson. These cloud platforms provide Natural Language Processing, Artificial Intelligence and Mobile Backend as a Service for chatbot development.\r\nSome Companies like Microsoft Azure and AARC are currently providing their Bot Engines through which chatbot Platforms or Software can be developed.","materialsDescription":"New tools designed to simplify the interaction between humans and computers have hit the market: Chatbots or Virtual Assistants. In banking, chatbots and virtual assistants are some of the industry’s newest tools designed to simplify the interaction between humans and computers.\r\n<span style=\"font-weight: bold;\">What is a chatbot?</span>\r\nA chatbot is artificial intelligence (AI) software that can simulate a conversation (or a chat) with a user in natural language through messaging applications, websites, mobile apps or through the telephone.\r\n<span style=\"font-weight: bold;\">Why are chatbots important?</span>\r\nA chatbot is often described as one of the most advanced and promising expressions of interaction between humans and machines. However, from a technological point of view, a chatbot only represents the natural evolution of a Question-Answering system leveraging Natural Language Processing (NLP). Formulating responses to questions in natural language is one of the most typical examples of Natural Language Processing applied in various enterprises’ end-use applications.\r\n<span style=\"font-weight: bold;\">How does a chatbot work?</span>\r\nThere are two different tasks at the core of a chatbot:\r\n<ol><li>user request analysis</li><li>returning the response</li></ol>\r\nUser request analysis: this is the first task that a chatbot performs. It analyzes the user’s request to identify the user intent and to extract relevant entities.\r\nThe ability to identify the user’s intent and extract data and relevant entities contained in the user’s request is the first condition and the most relevant step at the core of a chatbot: If you are not able to correctly understand the user’s request, you won’t be able to provide the correct answer.\r\nReturning the response: once the user’s intent has been identified, the chatbot must provide the most appropriate response for the user’s request. The answer may be:\r\n<ul><li>a generic and predefined text;</li><li>a text retrieved from a knowledge base that contains different answers;</li><li>a contextualized piece of information based on data the user has provided;</li><li>data stored in enterprise systems;</li><li>the result of an action that the chatbot performed by interacting with one or more backend application;</li><li>a disambiguating question that helps the chatbot to correctly understand the user’s request.</li></ul>\r\n<span style=\"font-weight: bold;\">In what is the benefit of chatbots?</span>\r\nChatbot applications streamline interactions between people and services, enhancing the customer experience. At the same time, they offer companies new opportunities to improve the customer's engagement process and operational efficiency by reducing the typical cost of customer service.\r\nTo be successful, a chatbot solution should be able to effectively perform both of these tasks. Human support plays a key role here: Regardless of the kind of approach and the platform, human intervention is crucial in configuring, training and optimizing the chatbot system.\r\n<span style=\"font-weight: bold;\">Which chatbot application is right for you?</span>\r\nThere are different approaches and tools that you can use to develop a chatbot. Depending on the use case you want to address, some chatbot technologies are more appropriate than others. In order to achieve the desired results, the combination of different AI forms such as natural language processing, machine learning, and semantic understanding may be the best option.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Chatbot_Development.png"},{"id":665,"title":"User Interface Development","alias":"user-interface-development","description":" User interface design (UI) or user interface engineering is the design of user interfaces for machines and software, such as computers, home appliances, mobile devices, and other electronic devices, with the focus on maximizing usability and the user experience. The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals (user-centered design).\r\nGood user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design and typography are utilized to support its usability, influencing how the user performs certain interactions and improving the aesthetic appeal of the design; design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs.\r\nInterface design is involved in a wide range of projects from computer systems, to cars, to commercial planes; all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge. As a result, designers tend to specialize in certain types of projects and have skills centered on their expertise, whether it is a software design, user research, web design, or industrial design.","materialsDescription":" <span style=\"font-weight: bold;\">What is a Graphical User Interface?</span>\r\nThe graphical user interface, developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple’s Macintosh and Microsoft’s Windows operating systems, was designed as a response to the problem of inefficient usability in early, text-based command-line interfaces for the average user.\r\nGraphical user interfaces would become the standard of user-centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bars, windows, tabs, menus, cursors, and the mouse pointing device. Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities.\r\n<span style=\"font-weight: bold;\">How Does a Graphical User Interface Work?</span>\r\nGraphical user interface design principles conform to the model–view–controller software pattern, which separates internal representations of information from the manner in which information is presented to the user, resulting in a platform where users are shown which functions are possible rather than requiring the input of command codes. Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task.\r\nThe appearance, or “skin,” of an operating system or application software may be redesigned at will due to the nature of graphical user interfaces being independent from application functions. Applications typically implement their own unique graphical user interface display elements in addition to graphical user interface elements already present on the existing operating system. A typical graphical user interface also includes standard formats for representing graphics and text, making it possible to share data between applications running under common graphical user interface design software.\r\nGraphical user interface testing refers to the systematic process of generating test cases in order to evaluate the functionality of the system and its design elements. Graphical user interface testing tools, which are either manual or automated and typically implemented by third-party operators, are available under a variety of licenses and are supported by a variety of platforms. Popular examples include: Tricentis Tosca, Squish GUI Tester, Unified Functional Testing (UFT), Maveryx, Appium, and eggPlant Functional.\r\n<span style=\"font-weight: bold;\">Graphical User Interface Examples</span>\r\nSketchpad, believed to be the first graphical computer-aided design program, was developed in 1962 by Ivan Sutherland while he was at MIT, and consisted of a light pen that enabled users to create and manipulate objects in engineering drawings in real-time with coordinated graphics.\r\nModern operating systems and graphical user interfaces are incorporated into nearly every interactive application, such as ATMs, self-service checkouts, airline self-ticketing and check-in, video games, smartphones, and desktops. Some popular, modern graphical user interface examples include Microsoft Windows, macOS, Ubuntu Unity, and GNOME Shell for desktop environments, and Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS, and Firefox OS for smartphones.\r\n<span style=\"font-weight: bold;\">Advantages of Graphical User Interfaces</span>\r\nThe advantage of a graphical user interface is a stark improvement in useability for the average person. The features of a graphical user interface leverage familiar metaphors, such as drag-and-drop for transferring files, and use familiar icons, such as a trash bin for deleted files, creating an environment in which computer operations are intuitive and easily mastered without any prior practice or knowledge of computing machinery or languages. Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_User_Interface_Development.png"},{"id":655,"title":"Perl Development","alias":"perl-development","description":" Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. &quot;Perl&quot; refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned &quot;sister language&quot;, Perl 6, before the latter's name was officially changed to Raku in October 2019.\r\nThough Perl is not officially an acronym, there are various backronyms in use, including &quot;Practical Extraction and Reporting Language&quot;. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another.\r\nThe Perl languages borrow features from other programming languages including C, shell script (sh), AWK, and sed; Wall also alludes to BASIC and Lisp in the introduction to Learning Perl (Schwartz &amp; Christiansen) and so on. They provide text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools, facilitating manipulation of text files. Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its unsurpassed regular expression and string parsing abilities.\r\nIn addition to CGI, Perl 5 is used for system administration, network programming, finance, bioinformatics, and other applications, such as for GUIs. It has been nicknamed &quot;the Swiss Army chainsaw of scripting languages&quot; because of its flexibility and power, and also its ugliness. In 1998, it was also referred to as the &quot;duct tape that holds the Internet together,&quot; in reference to both its ubiquitous use as a glue language and its perceived inelegance.\r\nAccording to Wall, Perl has two slogans. The first is &quot;There's more than one way to do it,&quot; commonly known as TMTOWTDI. The second slogan is &quot;Easy things should be easy and hard things should be possible&quot;.\r\nThe overall structure of Perl derives broadly from C. Perl is procedural in nature, with variables, expressions, assignment statements, brace-delimited blocks, control structures, and subroutines.\r\nPerl also takes features from shell programming. All variables are marked with leading sigils, which allow variables to be interpolated directly into strings. However, unlike the shell, Perl uses sigils on all accesses to variables, and unlike most other programming languages that use sigils, the sigil doesn't denote the type of the variable but the type of the expression. So for example, to access a list of values in a hash, the sigil for an array (&quot;@&quot;) is used, not the sigil for a hash (&quot;%&quot;). Perl also has many built-in functions that provide tools often used in shell programming (although many of these tools are implemented by programs external to the shell) such as sorting, and calling operating system facilities.\r\nPerl takes lists from Lisp, hashes (&quot;associative arrays&quot;) from AWK, and regular expressions from sed. These simplify and facilitate many parsing, text-handling, and data-management tasks. Also shared with Lisp are the implicit return of the last value in a block, and the fact that all statements have a value, and thus are also expressions and can be used in larger expressions themselves.\r\nAll versions of Perl do automatic data-typing and automatic memory management. The interpreter knows the type and storage requirements of every data object in the program; it allocates and frees storage for them as necessary using reference counting (so it cannot deallocate circular data structures without manual intervention). Legal type conversions — for example, conversions from number to string — are done automatically at run time; illegal type conversions are fatal errors.","materialsDescription":" <span style=\"font-weight: bold;\">What is Perl?</span>\r\n<ul><li>Perl is a stable, cross-platform programming language.</li><li>Though Perl is not officially an acronym few people used it as <span style=\"font-weight: bold;\">Practical Extraction and Report Language</span>.</li><li>It is used for mission-critical projects in the public and private sectors.</li><li>Perl is an Open Source software, licensed under its Artistic License, or the <span style=\"font-style: italic;\">GNU General Public License (GPL)</span>.</li><li>Perl was created by Larry Wall.</li><li>Perl 1.0 was released to Usenet's alt.comp.sources in 1987.</li><li>Perl is listed in the Oxford English Dictionary.</li></ul>\r\n<span style=\"font-weight: bold;\">What are the features of Perl programming?</span>\r\n<ul><li>Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others.</li><li>Perl's database integration interface DBI supports third-party databases including Oracle, Sybase, Postgres, MySQL, and others.</li><li>Perl works with HTML, XML, and other mark-up languages.</li><li>Perl supports Unicode.</li><li>Perl is Y2K compliant.</li><li>Perl supports both procedural and object-oriented programming.</li><li>Perl interfaces with external C/C++ libraries through XS or SWIG.</li><li>Perl is extensible.

Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects), and verifying that the software product is fit for use.\r\nSoftware testing involves the execution of a software component or system component to evaluate one or more properties of interest.

As a result, software testing typically (but not exclusively) attempts to execute a program or application with the intent of finding software bugs (errors or other defects). The job of testing is an iterative process as when one bug is fixed, it can illuminate other, deeper bugs, or can even create new ones.\r\nSoftware testing can provide objective, independent information about the quality of software and risk of its failure to users or sponsors.\r\nSoftware testing can be conducted as soon as executable software (even if partially complete) exists. The overall approach to software development often determines when and how testing is conducted. For example, in a phased process, most testing occurs after system requirements have been defined and then implemented in testable programs.
