These types of databases allow users to do more than simply view archived data. Operational databases allow you to modify that data (add, change or delete data), doing it in real-time. OLTP databases provide transactions as the main abstraction to guarantee data consistency that guarantees the so-called ACID properties. Basically, the consistency of the data is guaranteed in the case of failures and/or concurrent access to the data.\r\nSince the early 90s, the operational database software market has been largely taken over by SQL engines. Today, the operational DBMS market (formerly OLTP) is evolving dramatically, with new, innovative entrants and incumbents supporting the growing use of unstructured data and NoSQL DBMS engines, as well as XML databases and NewSQL databases. NoSQL databases typically have focused on scalability and have renounced to data consistency by not providing transactions as OLTP systems do. Operational databases are increasingly supporting distributed database architecture that can leverage distribution to provide high availability and fault tolerance through replication and scale-out ability.\r\nThe growing role of operational databases in the IT industry is moving fast from legacy databases to real-time operational databases capable to handle distributed web and mobile demand and to address Big data challenges. Recognizing this, Gartner started to publish the Magic Quadrant for Operational Database Management Systems in October 2013.\r\nOperational databases are used to store, manage and track real-time business information. For example, a company might have an operational database used to track warehouse/stock quantities. As customers order products from an online web store, an operational database can be used to keep track of how many items have been sold and when the company will need to reorder stock. An operational database stores information about the activities of an organization, for example, customer relationship management transactions or financial operations, in a computer database.\r\nOperational databases allow a business to enter, gather, and retrieve large quantities of specific information, such as company legal data, financial data, call data records, personal employee information, sales data, customer data, data on assets and much other information. An important feature of storing information in an operational database is the ability to share information across the company and over the Internet. Operational databases can be used to manage mission-critical business data, to monitor activities, to audit suspicious transactions, or to review the history of dealings with a particular customer. They can also be part of the actual process of making and fulfilling a purchase, for example in e-commerce.","materialsDescription":" <span style=\"font-weight: bold;\">What is DBMS used for?</span>\r\nDBMS, commonly known as Database Management System, is an application system whose main purpose revolves around the data.

IT outsourcing can be implemented both ways: outsides or within the country. \r\nIT outsourcing vendors can provide either a fully managed service, meaning they take full responsibility of all IT maintenance and support, or they can provide additional support for an internal IT team when needed, which is known as co-sourced IT support. A company using IT outsourcing can choose to use one provider for all their IT functions or split the work among multiple providers. \r\n<span style=\"font-weight: bold;\">Specific IT services typically outsourced include:</span>\r\n<ul><li>Application development</li><li>Web hosting</li><li>Application support</li><li>Database development</li><li>Telecommunications</li><li>Networking</li><li>Disaster recovery</li><li>Security</li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">Reasons for Outsourcing</span></p>\r\n<span style=\"font-weight: bold; \">To Reduce Cost.</span> More often than not, outsourcing means saving money. This is often due to lower labor costs, cheaper infrastructure, or an advantageous tax system in the outsourcing location.<br /><span style=\"font-weight: bold; \">To Access Skills That Are Unavailable Locally.</span> Resources that are scarce at home can sometimes be found in abundance elsewhere, meaning you can easily reach them through outsourcing.<br /><span style=\"font-weight: bold; \">To Better Use Internal Resources</span>.

The project manager from the outsourced team carries full responsibility for the quality and performance of the project.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Dedicated Team Model.</span> The client hires a team that will create a project for them, and they will work only on that project. Unlike the project-based model, a dedicated team is more engaged in your project. In this model, an outsourced team becomes your technical and product advisor. So it can offer ideas and suggest alternative solutions.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Outstaff Model.</span> It's a type of outsourcing in IT when you don't need a full-fledged development team and hire separate specialists. Sometimes the project requires finding a couple of additional professionals, and you're free to hire outstaff workers to cover that scope of work.</p>\r\n<h3 class=\"align-center\"><span style=\"font-weight: bold; \">What are IT Outsourcing examples?</span></h3>\r\nThe individual or company that becomes your outsourcing partner can be located anywhere in the world — one block away from your office or on another continent.\r\nA Bay Area-based startup partnering with an app development team in Utah and a call center in the Philippines, or a UK-based digital marketing agency hiring a Magento developer from Ukraine are both examples of outsourcing.\r\n<h3 class=\"align-center\">Why You Should Use IT Outsourcing</h3>\r\nNow that you know what IT outsourcing is, its models, and types, it's time to clarify why you need to outsource and whether you really need it. Let's go over a few situations that suggest when to opt for IT outsourcing.\r\n<ul><li><span style=\"font-weight: bold;\">You are a domain expert with idea</span></li></ul>\r\nIf you're an industry expert with the idea that solves a real problem, IT outsourcing is your choice. In this case, your main goal is to enter the market and test the solution fast. An outsourced team will help you validate the idea, build an MVP to check the hypothesis, and implement changes in your product according to market needs. It saves you money, time and lets you reach the goal.\r\n<ul><li><span style=\"font-weight: bold;\">You have an early-stage startup</span></li></ul>\r\nIt's a common case that young startups spend money faster than they get a solid team and a ready-to-market product. The Failory found that financial problems are the 3rd reason why startup fails. So it makes more sense to reduce costs by hiring an outsourced team of professionals while your business lives on investor's money. You may employ a full-cycle product development studio covering all the blind spots and bringing your product to life.\r\n<ul><li><span style=\"font-weight: bold;\">You need a technical support</span></li></ul>\r\nEven if you already have a ready solution, but it demands some technical improvements – frameworks for backend components, new language, integrations with enterprise software, UX&amp;UI design – it makes more sense to find an experienced partner. There are many functions that IT outsourcing can cover, and again it saves you the time you'd otherwise spend on looking for qualified staff.<br /><br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IT_outsourcing.png","alias":"it-outsourcing"},"66":{"id":66,"title":"BPM - Business Process Management","description":"<span style=\"font-weight: bold; \">Business process management (BPM)</span> is a discipline in operations management in which people use various methods to discover, model, analyze, measure, improve, optimize, and automate business processes. BPM focuses on improving corporate performance by managing business processes. Any combination of methods used to manage a company's business processes is BPM. Processes can be structured and repeatable or unstructured and variable.\r\nAs an approach, BPM sees processes as important assets of an organization that must be understood, managed, and developed to announce and deliver value-added products and services to clients or customers. This approach closely resembles other total quality management or continuous improvement process methodologies. ISO 9000 promotes the process approach to managing an organization.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Successfully employing BPM usually involves the following:</span>\r\nOrganizing around outcomes not tasks to ensure the proper focus is maintained\r\nCorrecting and improving processes before (potentially) automating them; otherwise all you’ve done is make the mess run faster\r\nEstablishing processes and assigning ownership lest the work and improvements simply drift away – and they will, as human nature takes over and the momentum peters out\r\nStandardizing processes across the enterprise so they can be more readily understood and managed, errors reduced, and risks mitigated\r\nEnabling continuous change so the improvements can be extended and propagated over time\r\nImproving existing processes, rather than building radically new or “perfect” ones, because that can take so long as to erode or negate any gains achieved\r\n<span style=\"font-weight: bold; \">Business Process Management Software (BPMS)</span> is a process automation tool. It helps you map out your everyday processes to identify and eliminate bottlenecks, control your company’s costs, make your day-to-day processes as efficient as possible, and ensure the effectiveness of the people involved in your processes. A business process management solution to a company’s needs begins with the alignment of business goals with an eye toward creating value through process change initiatives. This alignment leads to a thorough understanding and design of representative processes typically following an industry standard framework \r\nA BPM based foundation provides for complete lifecycle management of business processes, integration across technologies, and imbeds efficiency among people, processes, and technologies.\r\nCommercial business process management tools tend to center on the automation of business processes, essentially moving them from manual pen-and-paper endeavors to effortless automated transactions.

It has to be adhered to in order to satisfy either a required common approach to a particular event or regulatory requirements for the industry that the organisation is part of. It is a statement of truth about an organisation and is an attempt to describe the operations of an organisation, not an attempt to prescribe how an organisation should operate.\r\nBusiness Rules Management Software is a software component that is used to define, register, verify consistency, deploy, execute, monitor and manage the variety and complexity of decision logic that is used by operational systems within an organisation or enterprise. This logic, also referred to as business rules, includes policies, requirements, and conditional statements that are used to determine the tactical actions that take place in applications and systems. The BRMS software also provides the ability to define the relationships between different rules, and relate some of these rules to IT applications that are affected or need to enforce one or more of the rules.\r\nA Business Rules Management System Software acts as a central repository for business rules. Decision owners and IT employees can collaborate to develop, version, and edit rules in a single-sourced environment. A BRMS helps businesses automate tasks, improve consistency, and shorten turnaround on policy changes. BRMS vendors provide tools for developing, tracking, and editing business rules. Often, these tools support both programmers and non-programmers. Vendors also provide an engine to simulate and validate business rules before they are implemented. \r\n<p class=\"align-center\">Business Rule Management System includes, at minimum:</p>\r\n<ul><li>A repository, allowing the defined rules to be managed in terms of versions and variants and be available for reuse;</li><li>A development environment, which provides tools for both technical developers and business experts to define and manage the business rules;</li><li>A runtime environment, allowing applications to invoke business rules management and execute it using a business rules engine;</li><li>A management environment that provides the ability to not only monitor the development and runtime environments, but also manage them both.</li></ul>","materialsDescription":"<h1 class=\"align-center\">What are the business rules?</h1>\r\n<div>Business rules are statements that will guide the proper functioning of your business.

Most spatial databases allow the representation of simple geometric objects such as points, lines and polygons. Some spatial databases handle more complex structures such as 3D objects, topological coverages, linear networks, and TINs. While typical databases have developed to manage various numeric and character types of data, such databases require additional functionality to process spatial data types efficiently, and developers have often added geometry or feature data types. The Open Geospatial Consortium (OGC) developed the Simple Features specification (first released in 1997) and sets standards for adding spatial functionality to database systems. The SQL/MM Spatial ISO/IEC standard is a part the SQL/MM multimedia standard and extends the Simple Features standard with data types that support circular interpolations.\r\nA geodatabase (also geographical database and geospatial database) is a database of geographic data, such as countries, administrative divisions, cities, and related information. Such databases can be useful for websites that wish to identify the locations of their visitors for customization purposes.\r\nDatabase systems use indexes to quickly look up values; however, this way of indexing data is not optimal for spatial queries. Instead, spatial databases use a spatial index to speed up database operations.\r\nIn addition to typical SQL queries such as SELECT statements, spatial databases can perform a wide variety of spatial operations. The following operations and many more are specified by the Open Geospatial Consortium standard:\r\n<ul><li>Spatial Measurements: Computes line length, polygon area, the distance between geometries, etc.</li><li>Spatial Functions: Modify existing features to create new ones, for example by providing a buffer around them, intersecting features, etc.</li><li>Spatial Predicates: Allows true/false queries about spatial relationships between geometries. Examples include &quot;do two polygons overlap&quot; or 'is there a residence located within a mile of the area we are planning to build the landfill?'</li><li>Geometry Constructors: Creates new geometries, usually by specifying the vertices (points or nodes) which define the shape.</li><li>Observer Functions: Queries which return specific information about a feature such as the location of the center of a circle.</li></ul>\r\nSome databases support only simplified or modified sets of these operations, especially in cases of NoSQL systems like MongoDB and CouchDB.","materialsDescription":"<span style=\"font-weight: bold;\">What is the spatial index?</span>\r\nSpatial indices are used by spatial databases (databases which store information related to objects in space) to optimize spatial queries.

Therefore, RDBMSes are a subset of DBMSes.\r\nA relational database refers to a database that stores data in a structured format, using rows and columns. This makes it easy to locate and access specific values within the database. It is &quot;relational&quot; because the values within each table are related to each other. Tables may also be related to other tables. The relational structure makes it possible to run queries across multiple tables at once.\r\nWhile a relational database describes the type of database an RDMBS manages, the RDBMS refers to the database program itself. It is the software that executes queries on the data, including adding, updating, and searching for values.\r\nAn RDBMS may also provide a visual representation of the data. For example, it may display data in a tables like a spreadsheet, allowing you to view and even edit individual values in the table. Some relational database softwareallow you to create forms that can streamline entering, editing, and deleting data.\r\nMost well known DBMS applications fall into the RDBMS category. Examples include Oracle Database, MySQL, Microsoft SQL Server, and IBM DB2. Some of these programs support non-relational databases, but they are primarily used for relational database management.\r\nExamples of non-relational databases include Apache HBase, IBM Domino, and Oracle NoSQL Database. These type of databases are managed by other DMBS programs that support NoSQL, which do not fall into the RDBMS category.\r\nElements of the relational DBMS that overarch the basic relational database are so intrinsic to operations that it is hard to dissociate the two in practice.\r\nThe most basic features of RDBMS are related to create, read, update and delete operations, collectively known as CRUD. They form the foundation of a well-organized system that promotes consistent treatment of data.\r\nThe RDBMS typically provides data dictionaries and metadata collections useful in data handling. These programmatically support well-defined data structures and relationships. Data storage management is a common capability of the RDBMS, and this has come to be defined by data objects that range from binary large object (blob) strings to stored procedures. Data objects like this extend the scope of basic relational database operations and can be handled in a variety of ways in different RDBMSes.\r\nThe most common means of data access for the RDBMS is via SQL. Its main language components comprise data manipulation language (DML) and data definition language (DDL) statements. Extensions are available for development efforts that pair SQL use with common programming languages, such as COBOL (Common Business-Oriented Language), Java and .NET.\r\nRDBMSes use complex algorithms that support multiple concurrent user access to the database, while maintaining data integrity. Security management, which enforces policy-based access, is yet another overlay service that the RDBMS provides for the basic database as it is used in enterprise settings.\r\nRDBMSes support the work of database administrators (DBAs) who must manage and monitor database activity. Utilities help automate data loading and database backup. RDBMS systems manage log files that track system performance based on selected operational parameters. This enables measurement of database usage, capacity and performance, particularly query performance. RDBMSes provide graphical interfaces that help DBAs visualize database activity.\r\nRelational database management systems are central to key applications, such as banking ledgers, travel reservation systems and online retailing. As RDBMSes have matured, they have achieved increasingly higher levels of query optimization, and they have become key parts of reporting, analytics and data warehousing applications for businesses as well. \r\nRDBMSes are intrinsic to operations of a variety of enterprise applications and are at the center of most master data management (MDM) systems.<br /><br />","materialsDescription":"<h1 class=\"align-center\"> <span style=\"font-weight: normal;\">What are the advantages of a Relational Database Management System?</span></h1>\r\nA Relational Database Management System (RDBMS) is a software system that provides access to a relational database. The software system is a collection of software applications that can be used to create, maintain, manage and use the database. A &quot;relational database&quot; is a database structured on the &quot;relational&quot; model. Data are stored and presented in a tabular format, organized in rows and columns with one record per row.\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Data Structure.</span> The table format is simple and easy for database users to understand and use. Relational database management software provide data access using a natural structure and organization of the data. Database queries can search any column for matching entries.</li></ul>\r\n<dl></dl>\r\n<ul><li><span style=\"font-weight: bold;\">Multi-User Access.</span> RDBMS database program allow multiple database users to access a database simultaneously. Built-in locking and transactions management functionality allow users to access data as it is being changed, prevents collisions between two users updating the data, and keeps users from accessing partially updated records.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Privileges. </span>Authorization and privilege control features in an RDBMS allow the database administrator to restrict access to authorized users, and grant privileges to individual users based on the types of database tasks they need to perform. Authorization can be defined based on the remote client IP address in combination with user authorization, restricting access to specific external computer systems.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Network Access.</span> RDBMSs provide access to the database through a server daemon, a specialized software program that listens for requests on a network, and allows database clients to connect to and use the database. Users do not need to be able to log in to the physical computer system to use the database, providing convenience for the users and a layer of security for the database. Network access allows developers to build desktop tools and Web applications to interact with databases.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Speed.</span> The relational database model is not the fastest data structure. RDBMS software advantages, such as simplicity, make the slower speed a fair trade-off. Optimizations built into an RDBMS, and the design of the databases, enhance performance, allowing RDBMSs to perform more than fast enough for most applications and data sets. Improvements in technology, increasing processor speeds and decreasing memory and storage costs allow systems administrators to build incredibly fast systems that can overcome any database performance shortcomings.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Maintenance. </span>RDBMSs feature maintenance utilities that provide database administrators with tools to easily maintain, test, repair and back up the databases housed in the system.

These kinds of databases require data manipulation techniques and processes designed to provide solutions to big data problems that big companies face. The most popular emerging non-relational database is called NoSQL (Not Only SQL).\r\nMost non-relational databases are incorporated into websites such as Google, Yahoo!, Amazon and Facebook. These websites introduce a slew of new applications every single day with millions and millions of users, so they would not be able to handle large traffic spikes with existing RDBMS solutions. Since RDBMS cannot handle the problem, they’ve switched to a new kind of DBMS that is capable of handling Web-scale data in a non-relational way.<br /><br />An interesting aspect of a non-relational database such as NoSQL is scalability. NoSQL uses the BASE system (basically available, soft-state, eventually consistent). Non-relational databases forgo the table form of rows and columns relational databases use in favor of specialized frameworks to store data, which can be accessed by special query APIs. Persistence is an important element in these databases. To enable fast throughput of vast amounts of data the best option for performance is &quot;in memory,&quot; rather than reading and writing from disks.<br /><br />Relational databases use the ACID system, which ensures consistency of data in all situations of data management but obviously takes longer to process because of all those relations and its branching nature. However, the BASE system loosened up the requirements on consistency to achieve better availability and partitioning for better scalability.","materialsDescription":" <span style=\"font-weight: bold; \">What are NoSQL databases?</span>\r\nNoSQL databases are purpose built for specific data models and have flexible schemas for building modern applications. NoSQL databases are widely recognized for their ease of development, functionality, and performance at scale. They use a variety of data models, including document, graph, key-value, in-memory, and search. This page includes resources to help you better understand NoSQL databases and to get started.\r\n<span style=\"font-weight: bold; \">How Does a NoSQL (nonrelational) Database Work?</span>\r\nNoSQL databases use a variety of data models for accessing and managing data, such as document, graph, key-value, in-memory, and search. These types of databases are optimized specifically for applications that require large data volume, low latency, and flexible data models, which are achieved by relaxing some of the data consistency restrictions of other databases.\r\nConsider the example of modeling the schema for a simple book database:\r\n<ul><li>In a relational database, a book record is often dissembled (or “normalized”) and stored in separate tables, and relationships are defined by primary and foreign key constraints. In this example, the Books table has columns for ISBN, Book Title, and Edition Number, the Authors table has columns for AuthorID and Author Name, and finally the Author-ISBN table has columns for AuthorID and ISBN. The relational model is designed to enable the database to enforce referential integrity between tables in the database, normalized to reduce the redundancy, and generally optimized for storage.</li><li>In a NoSQL database, a book record is usually stored as a JSON document. For each book, the item, ISBN, Book Title, Edition Number, Author Name, and AuthorID are stored as attributes in a single document. In this model, data is optimized for intuitive development and horizontal scalability.</li></ul>\r\n<span style=\"font-weight: bold; \">Why should you use a NoSQL database?</span>\r\nNoSQL databases are a great fit for many modern applications such as mobile, web, and gaming that require flexible, scalable, high-performance, and highly functional databases to provide great user experiences.\r\n<ul><li><span style=\"font-weight: bold; \">Flexibility:</span> NoSQL databases generally provide flexible schemas that enable faster and more iterative development. The flexible data model makes NoSQL databases ideal for semi-structured and unstructured data.</li><li><span style=\"font-weight: bold; \">Scalability:</span> NoSQL databases are generally designed to scale out by using distributed clusters of hardware instead of scaling up by adding expensive and robust servers. Some cloud providers handle these operations behind-the-scenes as a fully managed service.</li><li><span style=\"font-weight: bold; \">High-performance:</span> NoSQL database are optimized for specific data models (such as document, key-value, and graph) and access patterns that enable higher performance than trying to accomplish similar functionality with relational databases.</li><li><span style=\"font-weight: bold; \">Highly functional:</span> NoSQL databases provide highly functional APIs and data types that are purpose built for each of their respective data models.</li></ul>\r\n<span style=\"font-weight: bold;\">What are the types of NoSQL Databases?</span>\r\n<ul><li><span style=\"font-weight: bold;\">Key-value:</span> Key-value databases are highly partitionable and allow horizontal scaling at scales that other types of databases cannot achieve. Use cases such as gaming, ad tech, and IoT lend themselves particularly well to the key-value data model.</li><li><span style=\"font-weight: bold;\">Document:</span> In application code, data is represented often as an object or JSON-like document because it is an efficient and intuitive data model for developers. Document databases make it easier for developers to store and query data in a database by using the same document model format that they use in their application code. The flexible, semistructured, and hierarchical nature of documents and document databases allows them to evolve with applications’ needs. The document model works well with catalogs, user profiles, and content management systems where each document is unique and evolves over time.</li><li><span style=\"font-weight: bold;\">Graph:</span> A graph database’s purpose is to make it easy to build and run applications that work with highly connected datasets. Typical use cases for a graph database include social networking, recommendation engines, fraud detection, and knowledge graphs.</li><li><span style=\"font-weight: bold;\">In-memory:</span> Gaming and ad-tech applications have use cases such as leaderboards, session stores, and real-time analytics that require microsecond response times and can have large spikes in traffic coming at any time. Amazon ElastiCache offers Memcached and Redis, to serve low-latency, high-throughput workloads, such as McDonald’s, that cannot be served with disk-based data stores.</li><li><span style=\"font-weight: bold;\">Search:</span> Many applications output logs to help developers troubleshoot issues.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Nonrelational_Database_Management_Systems1.png","alias":"non-relational-database-management-systems"},"243":{"id":243,"title":"Database Development and Management Tools","description":" Many companies create various multi-functional applications to facilitate the management, development and administration of databases.\r\nMost relational databases consist of two separate components: a “back-end” where data is stored and a “front-end” —a user interface for interacting with data.

The system ensures the safety, reliability of storage and data integrity, as well as provides the means to administer the database.","materialsDescription":" <span style=\"font-weight: bold;\">The main functions of the DBMS:</span>\r\n<ul><li>data management in external memory (on disk);</li><li>data management in RAM using disk cache;</li><li>change logging, backup and recovery of databases after failures;</li><li>support for database languages ​​(data definition language, data manipulation language).</li></ul>\r\n<span style=\"font-weight: bold;\">The composition of the DBMS:</span>\r\nUsually, a modern DBMS contains the following components:\r\n<ul><li>the core, which is responsible for managing data in external and RAM and logging;</li><li>database language processor, which provides the optimization of requests for the extraction and modification of data and the creation, as a rule, of a machine-independent executable internal code;</li><li>a run-time support subsystem that interprets data manipulation programs that create a user interface with a DBMS;<br />service programs (external utilities) that provide a number of additional capabilities for maintaining an information system.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Database_Development_and_Management_Tools.png","alias":"database-development-and-management-tools"},"245":{"id":245,"title":"Data Integration and Access Software","description":" Data integration involves combining data residing in different sources and providing users with a unified view of them. This process becomes significant in a variety of situations, which include both commercial (such as when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains. Data integration appears with increasing frequency as the volume (that is, big data) and the need to share existing data explodes. It has become the focus of extensive theoretical work, and numerous open problems remain unsolved. Data integration encourages collaboration between internal as well as external users.\r\nData integration is the process of combining data from different sources into a single, unified view. Integration begins with the ingestion process, and includes steps such as cleansing, ETL mapping, and transformation. Data integration ultimately enables analytics tools to produce effective, actionable business intelligence.\r\nThere is no universal approach to data integration. However, data integration solutions typically involve a few common elements, including a network of data sources, a master server, and clients accessing data from the master server.\r\nIn a typical data integration process, the client sends a request to the master server for data. The master server then intakes the needed data from internal and external sources. The data is extracted from the sources, then consolidated into a single, cohesive data set. This is served back to the client for use.","materialsDescription":" <span style=\"font-weight: bold;\">Integration helps businesses succeed</span>\r\nEven if a company is receiving all the data it needs, that data often resides in a number of separate data sources. For example, for a typical customer 360 view use case, the data that must be combined may include data from their CRM systems, web traffic, marketing operations software, customer — facing applications, sales and customer success systems, and even partner data, just to name a few. Information from all of those different sources often needs to be pulled together for analytical needs or operational actions, and that can be no small task for data engineers or developers to bring them all together.\r\nLet’s take a look at a typical analytical use case. Without unified data, a single report typically involves logging into multiple accounts, on multiple sites, accessing data within native apps, copying over the data, reformatting, and cleansing, all before analysis can happen.\r\nConducting all these operations as efficiently as possible highlights the importance of data integration. It also showcases the major benefits of a well thought-out approach to data integration:\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Improves collaboration and unification of systems</span></span>\r\nEmployees in every department — and sometimes in disparate physical locations — increasingly need access to the company's data for shared and individual projects. IT needs a secure solution for delivering data via self-service access across all lines of business.\r\nAdditionally, employees in almost every department are generating and improving data that the rest of the business needs. Data integration needs to be collaborative and unified in order to improve collaboration and unification across the organization.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Saves time and boosts efficiency</span></span>\r\nWhen a company takes measures to integrate its data properly, it cuts down significantly on the time it takes to prepare and analyze that data. The automation of unified views cuts out the need for manually gathering data, and employees no longer need to build connections from scratch whenever they need to run a report or build an application.\r\nAdditionally, using the right tools, rather than hand-coding the integration, returns even more time (and resources overall) to the dev team.\r\nAll the time saved on these tasks can be put to other, better uses, with more hours earmarked for analysis and execution to make an organization more productive and competitive.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Reduces errors (and rework)</span></span>\r\nThere’s a lot to keep up with when it comes to a company’s data resources. To manually gather data, employees must know every location and account that they might need to explore — and have all necessary software installed before they begin — to ensure their data sets will be complete and accurate. If a data repository is added, and that employee is unaware, they will have an incomplete data set.\r\nAdditionally, without a data integration solution that synchronizes data, reporting must be periodically redone to account for any changes. With automated updates, however, reports can be run easily in real time, whenever they’re needed.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Delivers more valuable data</span></span>\r\nData integration efforts actually improve the value of a business’ data over time. As data is integrated into a centralized system, quality issues are identified and necessary improvements are implemented, which ultimately results in more accurate data — the foundation for quality analysis.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Data_Integration_and_Access_Software.png","alias":"data-integration-and-access-software"},"249":{"id":249,"title":"Development Languages, Environments, and Tools","description":" Free software development environments have different purposes: educational, developmental, educational, and the like. Their students can be schoolchildren, students, novice programmers.\r\nScientists propose the following classification of free software development environments:\r\n<ul><li>Environments that support one programming language;</li><li>Environments with support for multiple programming languages;</li><li>Development environments for web systems and applications;</li><li>Environments aimed at a children's audience.</li></ul>\r\nOf the free environments focused on a single programming language, the following tools should be highlighted: Lazarus, PyScripter, DrPython, Wing IDE.\r\nAmong the free software development tools designed for several programming languages, the following should be noted: CodeLite, Dev-C, Anjuta, Eric, Eclipse, HiAsm, Kylix, MonoDevelop, NetBeans, SharpDevelop, Xcode, etc.\r\nFrom the list of free environments for creating web applications, you can select the following: AJAX.OOP, MooTools Code :: Blocks, Codelobster PHP Edition, Geany, Ultimate, Symfony, Grails. With their help, experts also produce the creation of websites and Internet interfaces.\r\nAmong the development tools intended for children's audiences, the following environments can be singled out: Algo, Alice, EToys, Scratch, Squeak, etc. The main purpose of their use is to encourage children to learn to program.\r\nAn integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools, and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.\r\nThe boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development.\r\nIntegrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program in which all development is done. This program typically provides many features for authoring, modifying, compiling, deploying and debugging software. This contrasts with software development using unrelated tools, such as vi, GCC or make.\r\nOne aim of the IDE is to reduce the configuration necessary to piece together multiple development utilities, instead it provides the same set of capabilities as one cohesive unit. Reducing setup time can increase developer productivity, especially in cases where learning to use the IDE is faster than manually integrating and learning all of the individual tools. Tighter integration of all development tasks has the potential to improve overall productivity beyond just helping with setup tasks. For example, code can be continuously parsed while it is being edited, providing instant feedback when syntax errors are introduced. Allowing developers to debug code much faster and easier with an IDE.\r\nSome IDEs are dedicated to a specific programming language, allowing a feature set that most closely matches the programming paradigms of the language. However, there are many multiple-language IDEs.\r\nWhile most modern IDEs are graphical, text-based IDEs such as Turbo Pascal were in popular use before the widespread availability of windowing systems like Microsoft Windows and the X Window System (X11). They commonly use function keys or hotkeys to execute frequently used commands or macros.","materialsDescription":" <span style=\"font-weight: bold;\">What is &quot;software development tools&quot;?</span>\r\nSoftware development tools - a set of techniques, methods, techniques, as well as a set of tool programs (compilers, application/system libraries, etc.) used by the developer to create program code for the program that meets the specified requirements.\r\n<span style=\"font-weight: bold;\">What does &quot;program development&quot; mean?</span>\r\nProgram development is a complex process, the main purpose of which is to create and maintain a program code that provides the necessary level of reliability and quality.

These components might be as a software bundle, a web administration, asset or a module that contains related information or capacities.\r\nComponents from a pre-built software are autonomously removed and sold independently by the software designers themselves or through outsiders to help in building another software framework. The primary reason for component-based software construction is re ease of use in other software frameworks for construction and redesigning of existing software frameworks.\r\nSoftware Construction Components Market is rendered by expanding interest for new applications with enlarged highlights and customization capacities. The requirement for decreasing many-sided quality and expanding efficiency is fortifying the development of the software construction components market.

Reduced complexity is achieved through emphasizing the creation of code that is simple and readable rather than clever. Minimizing complexity is accomplished through making use of standards, and through numerous specific techniques in coding. It is also supported by the construction-focused quality techniques.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Anticipating change</span></span>\r\nAnticipating change helps software engineers build extensible software, which means they can enhance a software product without disrupting the underlying structure.

Creating a website design is usually a certain process, which takes into account various requirements of not only artistic but also technical nature. Such a process may include several stages:\r\n<ul><li>development of an attractive, easily perceived design of the start page, as well as other sections and subsequent levels (including various forms of registrations, baskets, etc.);</li><li>development and coordination of a well-designed structure of the entire site;</li><li>designing a convenient, fairly simple site navigation;</li><li>correctly positioned text on the pages;</li><li>availability of opportunities for simple support and expansion of the site.</li></ul>\r\n<span style=\"font-weight: bold;\">What design to choose when creating a site?</span>\r\nWhen creating a website design, you must take into account its theme.\r\nSo, a commercial website should attract visitors with its memorable look and corporate identity that is specific to your company. And, at the same time, be convenient and contain all the information necessary for the user about you and your goods, services. Not to mention the fact that various forms of receiving on-line consultations, placing orders, etc. are welcome on such a site. The presence of such functions and their intuitiveness and accessibility for the site user significantly increases what is commonly called the &quot;site conversion&quot;. Those. how much your site will be &quot;selling&quot;, and whether it can not only be an analogue of your company's business card on the Internet, but also attract new, by no means virtual clients for your business. Therefore, the creation of a website design of this kind should be carried out very carefully in order to fully reflect the individuality of the image of the company.\r\nSometimes it is recommended to adhere to a concise style, which is able to emphasize your uniqueness and stability as a company. In other cases (for example, if we are talking about the sites of wedding agencies), a certain tone is considered to be a certain romance and tenderness of the color scheme, combined with joyful, bright elements. And sites that appeal to potential customers with unusual requests are simply obliged to have a unique, sometimes very extravagant design (while maintaining, however, the basic principles of good usability - the simplicity and convenience of using your Internet resource).\r\nIf you plan, for example, to launch an information site, then its design should be designed in a strict style, without flashy colors, since in this case it is the content that is more important than the design.\r\nHowever, the last statement is true for any site. Indeed, sometimes it doesn’t matter how beautiful the wrapper is, if instead of candy inside the user finds a dummy. The content of the site, its content and how convenient it is for the user to receive the information he needs on your site is the most important thing! Alas, in the Russian Internet zone, so far, 9 out of 10 sites (even with an excellent initial design) are simply “killed” by inappropriate or uninteresting user content. And then, simply, its absence.\r\n<span style=\"font-weight: bold;\">Web design when creating sites: beauty or functionality?</span>\r\nWhen creating the design of the future site, it is important to remember, first of all, the functionality and the tasks that the future site will have to solve. And, therefore, remember about those for whom you are creating it - about future users. An overly elaborate design or an inconvenient menu, the difficulty of finding the necessary information on the site - this can lead to the fact that your visitor will go to other sites. Those. to your competitors.\r\nThe user of the Internet network often does not care about designer delights or the “coolness” of a programmer who has implemented non-standard site navigation, which you can’t even figure out without additional instructions. A site visitor came to you for information. And it is important, first of all, how quickly he found her, how much she met his needs, how much she helped in solving him, the user of the problem.\r\nThen the site will be remembered, and the visitor will not only return to you himself, but also, perhaps, will bring friends.\r\nA good web designer is not only, and not so much an artist, as a very thoughtful and experienced Internet resource designer who will attract attention, while remaining convenient and in demand within the framework of your marketing policy.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Web_Design_and_Development_Tools.png","alias":"web-design-and-development-tools"},"261":{"id":261,"title":"Automated Software Quality Tools","description":" Some software testing tasks, such as extensive low-level interface regression testing, can be laborious and time-consuming to do manually. In addition, a manual approach might not always be effective in finding certain classes of defects. Test automation offers a possibility to perform these types of testing effectively. Once automated tests have been developed, they can be run quickly and repeatedly. Many times, this can be a cost-effective method for regression testing of software products that have a long maintenance life. Even minor patches over the lifetime of the application can cause existing features to break which were working at an earlier point in time.\r\nThere are many approaches to test automation, however below are the general approaches used widely:\r\n<ul><li>Graphical user interface testing. A testing framework that generates user interface events such as keystrokes and mouse clicks, and observes the changes that result in the user interface, to validate that the observable behavior of the program is correct.</li><li>API driven testing. A testing framework that uses a programming interface to the application to validate the behaviour under test. Typically API driven testing bypasses application user interface altogether. It can also be testing public (usually) interfaces to classes, modules or libraries are tested with a variety of input arguments to validate that the results that are returned are correct.</li></ul>\r\nTest automation tools can be expensive, and are usually employed in combination with manual testing. Test automation can be made cost-effective in the long term, especially when used repeatedly in regression testing. A good candidate for test automation is a test case for common flow of an application, as it is required to be executed (regression testing) every time an enhancement is made in the application. Test automation reduces the effort associated with manual testing. Manual effort is needed to develop and maintain automated checks, as well as reviewing test results.\r\nIn automated testing the test engineer or software quality assurance person must have software coding ability, since the test cases are written in the form of source code which, when run, produce output according to the assertions that are a part of it. Some test automation tools allow for test authoring to be done by keywords instead of coding, which do not require programming.\r\nOne way to generate test cases automatically is model-based testing through use of a model of the system for test case generation, but research continues into a variety of alternative methodologies for doing so. In some cases, the model-based approach enables non-technical users to create automated business test cases in plain English so that no programming of any kind is needed in order to configure them for multiple operating systems, browsers, and smart devices.\r\nWhat to automate, when to automate, or even whether one really needs automation are crucial decisions which the testing (or development) team must make. A multi-vocal literature review of 52 practitioner and 26 academic sources found that five main factors to consider in test automation decision are: 1) System Under Test (SUT), 2) the types and numbers of tests, 3) test-tool, 4) human and organizational topics, and 5) cross-cutting factors. The most frequent individual factors identified in the study were: need for regression testing, economic factors, and maturity of SUT.","materialsDescription":"&nbsp;<span style=\"font-weight: bold;\">Unit testing</span>\r\nA growing trend in software development is the use of unit testing frameworks such as the xUnit frameworks (for example, JUnit and NUnit) that allow the execution of unit tests to determine whether various sections of the code are acting as expected under various circumstances. Test cases describe tests that need to be run on the program to verify that the program runs as expected.\r\nTest automation mostly using unit testing is a key feature of extreme programming and agile software development, where it is known as test-driven development (TDD) or test-first development. Unit tests can be written to define the functionality before the code is written. However, these unit tests evolve and are extended as coding progresses, issues are discovered and the code is subjected to refactoring. Only when all the tests for all the demanded features pass is the code considered complete. Proponents argue that it produces software that is both more reliable and less costly than code that is tested by manual exploration. It is considered more reliable because the code coverage is better, and because it is run constantly during development rather than once at the end of a waterfall development cycle. The developer discovers defects immediately upon making a change, when it is least expensive to fix. Finally, code refactoring is safer when unit testing is used; transforming the code into a simpler form with less code duplication, but equivalent behavior, is much less likely to introduce new defects when the refactored code is covered by unit tests.\r\n<span style=\"font-weight: bold;\">Graphical User Interface (GUI) testing</span>\r\nMany test automation tools provide record and playback features that allow users to interactively record user actions and replay them back any number of times, comparing actual results to those expected. The advantage of this approach is that it requires little or no software development. This approach can be applied to any application that has a graphical user interface. However, reliance on these features poses major reliability and maintainability problems. Relabelling a button or moving it to another part of the window may require the test to be re-recorded. Record and playback also often adds irrelevant activities or incorrectly records some activities.\r\nA variation on this type of tool is for testing of web sites. Here, the &quot;interface&quot; is the web page. However, such a framework utilizes entirely different techniques because it is rendering HTML and listening to DOM Events instead of operating system events. Headless browsers or solutions based on Selenium Web Driver are normally used for this purpose.\r\nAnother variation of this type of test automation tool is for testing mobile applications. This is very useful given the number of different sizes, resolutions, and operating systems used on mobile phones. For this variation, a framework is used in order to instantiate actions on the mobile device and to gather results of the actions.\r\nAnother variation is script-less test automation that does not use record and playback, but instead builds a model of the application and then enables the tester to create test cases by simply inserting test parameters and conditions, which requires no scripting skills.\r\n<span style=\"font-weight: bold; \">API driven testing</span>\r\nAPI testing is also being widely used by software testers due to the difficulty of creating and maintaining GUI-based automation testing. It involves directly testing APIs as part of integration testing, to determine if they meet expectations for functionality, reliability, performance, and security. Since APIs lack a GUI, API testing is performed at the message layer. API testing is considered critical when an API serves as the primary interface to application logic since GUI tests can be difficult to maintain with the short release cycles and frequent changes commonly used with agile software development and DevOps.\r\n<span style=\"font-weight: bold;\">Continuous testing</span>\r\nContinuous testing is the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with a software release candidate. For Continuous Testing, the scope of testing extends from validating bottom-up requirements or user stories to assessing the system requirements associated with overarching business goals.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Automated_Software_Quality_Tools1.png","alias":"automated-software-quality-tools"},"263":{"id":263,"title":"Software Configuration Management Tools","description":"<span style=\"font-weight: bold; \">Software configuration management</span> (SCM) is a set of processes, policies, and tools that organizes the development process.

If a configuration is working well, SCM can determine how to replicate it across many hosts. \r\nThe acronym &quot;SCM&quot; is also expanded as <span style=\"font-weight: bold; \">source configuration management process</span> and <span style=\"font-weight: bold; \">software change and configuration management.</span> However, &quot;configuration&quot; is generally understood to cover changes typically made by a system administrator. \r\nSoftware configuration control usually includes the updates and the versions that have been applied to software packages, as well as locations and network addresses of hardware devices. When a system needs a software or hardware upgrade, the user can access the configuration management program and database to see what is currently installed and then make a more informed decision about the upgradation needed. Configuration management tools list have been divided into three categories: <span style=\"font-weight: bold;\">tracking</span>, <span style=\"font-weight: bold;\">version management</span>, and r<span style=\"font-weight: bold;\">elease tools.</span>\r\nThe SCM configuration management traces changes and verifies that the software has all of the planned changes that are supposed to be included in a new release. It includes four procedures that should be defined for each software project to ensure that a reliable software configuration management process is utilized. The four procedures typically found in a reliable system configuration management tools are:\r\n<span style=\"font-weight: bold; \">Configuration identification. </span>It is the procedure by which attributes are identified that defines all the properties of a configuration item. A configuration item referred to as an object is a product (hardware and/or software) that supports use by an end user. These attributes are recorded in configuration documents or database tables and baselined. A baseline is an approved configuration object, such as a project plan, that has been authorized for implementation.\r\n<span style=\"font-weight: bold; \">Configuration control.</span> It is a set of processes and approval stages required to change a configuration object’s attributes and to rebaseline them.<span style=\"font-weight: bold; \"><br /></span>\r\n<span style=\"font-weight: bold; \">Configuration status documentation. </span>Configuration status accounting is the ability to record and report on the configuration baselines associated with each configuration object at any point in time.\r\n<span style=\"font-weight: bold; \">Configuration audits. </span>Configuration audits are divided into functional and physical configuration audits. An audit occurs at the time of delivery of a project or at the time a change is made. A functional configuration audit is intended to make sure that functional and performance attributes of a configuration object are achieved. A physical configuration audit attempts to ensure that a configuration object is installed based on the requirements of its design specifications.\r\n<span style=\"font-weight: bold; \">The advantages of software configuration management system are:</span>\r\n<ul><li>It reduces redundant work</li><li>It effectively manages simultaneous updates</li><li>It avoids configuration related problems</li><li>It simplifies coordination between team members</li><li>It is helpful in tracking defects</li></ul>\r\n\r\n\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> What are the outcomes of well-implemented configuration management?</h1>\r\n<ul><li><span style=\"font-weight: bold; \">Disaster Recovery<br /></span></li></ul>\r\nIf the worst does happen, automated configuration management tools ensures that our assets are easily recoverable. The same applies to rollbacks. Configuration management makes it so that when we’ve put out bad code, we can go back to the state of our software before the change.\r\n<ul><li><span style=\"font-weight: bold; \">Uptime and Site Reliability</span></li></ul>\r\nThe term “site reliability” refers to how often your service is up. A frequent cause of downtime is bad deployments, which can be caused by differences in running production servers to test servers. With our configuration managed properly, our test environments can mimic production, so there’s less chance of a nasty surprise.\r\n<ul><li><span style=\"font-weight: bold; \">Easier Scaling</span></li></ul>\r\nProvisioning is the act of adding more resources (usually servers) to our running application. Сonfiguration automation tools ensure that we know what a good state of our service is. That way, when we want to increase the number of servers that we run, it’s simply a case of clicking a button or running a script. The goal is really to make provisioning a non-event.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Software_Configuration_Management_Tools.png","alias":"software-configuration-management-tools"},"393":{"id":393,"title":"Embedded Database Management Systems","description":" An embedded database is a database technology in which database management solutions are built into an application rather than provided as standalone tools.

It can include traditional relational database designs or other kinds of storage formats. It can utilize different solutions as well; for example, a popular type of embedded architecture uses MS Access for storage and relies on VBA forms to handle data requests. Many of these systems also use various APIs and SQL tools to perform data-related tasks.\r\nEmbedded database designs are used for various purposes. Embedded database tools, for example, can be used for email archive searches, for presentation of gaming statistics or other stored game data, and for industry-specific tools like tax-preparation software packages.\r\nIT professionals also sometimes use the term embedded database to refer to database solutions that run on mobile devices.","materialsDescription":"&nbsp;<span style=\"font-weight: bold; \">What do &quot;Embedded Database Management Systems&quot; mean?</span>\r\nAn embedded database system is a database management system (DBMS) which is tightly integrated with an application software that requires access to stored data, such that the database system is &quot;hidden&quot; from the application’s end-user and requires little or no ongoing maintenance.\r\n<span style=\"font-weight: bold;\">What does it include?</span>\r\nIt is actually a broad technology category that includes\r\n<ul><li>database systems with differing application programming interfaces (SQL as well as proprietary, native APIs),</li><li>database architectures (client-server and in-process),</li><li>storage modes (on-disk, in-memory, and combined),</li><li>database models (relational, object-oriented, entity–attribute–value model, network/CODASYL),</li><li>target markets.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Embedded_Database_Management_Systems.png","alias":"embedded-database-management-systems"},"395":{"id":395,"title":"Agile Application Life-Cycle Management Software","description":" Agile software development is an approach to software development under which requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams and their customer(s)/end user(s). It advocates adaptive planning, evolutionary development, empirical knowledge, and continual improvement, and it encourages rapid and flexible response to change.\r\nThe term agile (sometimes written Agile) was popularized, in this context, by the Manifesto for Agile Software Development. The values and principles espoused in this manifesto were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban.\r\nThere is significant anecdotal evidence that adopting agile practices and values improves the agility of software professionals, teams and organizations; however, some empirical studies have found no scientific evidence.\r\nAgile application lifecycle management (Agile ALM) is all the tools and processes that are used to manage software development projects based on flexible methodology. The traditional cascade design model uses a phase approach to the development life cycle. This approach means that no project phase starts earlier than the previous one ends. For example, the design does not begin before the collection of requirements ends. Development does not begin until the design is completed. Testing does not begin until development is fully completed. There are many tools to manage what is in the input and output of each phase.","materialsDescription":" Agile ALM brings together two seemingly contradictory development strategies. Agile promotes flexibility, rapid release cycles and quick response to change. Application lifecycle management (ALM) emphasizes tracking and documenting changes in an application -- from inception to retirement. Its processes are more controlled and less adaptive than the Agile methodology. That said, when put together, Agile and ALM act as complements, rending ALM more flexible and Agile more disciplined.\r\n<span style=\"font-weight: bold;\">What is Agile ALM?</span>\r\nDevelopment expert Yvette Francino described Agile ALM as ALM tools and processes that are used to manage Agile software development projects. For example, rather than using Waterfall's phased approach, Agile ALM offers an approach to software development in which design, code and requirements are all handled by the same team.\r\n<span style=\"font-weight: bold;\">How do you integrate Agile into an ALM framework?</span>\r\nAccording to Gerie Owen's article on Agile and ALM, adopting Agile means both a change to the ALM approach and a change to an organization's mind-set. An Agile ALM strategy will focus on the customer and will have the ability to adapt to shifting requirements -- from project planning to release management. For example, instead of just implementing controls to force early feedback from testers and business analysts, an organization would also foster a culture of collaboration.\r\n<span style=\"font-weight: bold;\">Are there tools that can help me achieve this?</span>\r\nALM tools are widely available but must be chosen with care, according to Yvette Francino, SearchSoftwareQuality contributor. Organizations should look for tools that facilitate the process without impeding acceptance of changing requirements. They would also need to integrate throughout the application lifecycle and be easy to maintain. In other words, the tool should manage the development process in an Agile way. In an article for SearchSoftwareQuality.com, Amy Reichert provides a list of Agile ALM tools and identifies their strengths and weaknesses. Rally Software, for example, offers a product that works well with Agile but, according to Reichert, does not provide an intuitive workflow. VersionOne, on the other hand, offers a tool that is more user-friendly but less compatible with Agile. Which one is best will depend on the company's needs.\r\n<span style=\"font-weight: bold;\">Are there challenges to Agile ALM that I should be aware of?</span>\r\nThe primary challenge to Agile ALM is in finding a balance between the two methodologies. A common pitfall is to over-ALM the development process. In other words, when developers and testers start to find workarounds to the software rules -- as they often do -- some react by creating more rules in order to more strictly enforce them. Meanwhile, processes lose their agility.\r\n<span style=\"font-weight: bold;\">How can I overcome these challenges?</span>\r\nTesting expert Amy Reichert cautions development teams to keep track of how many rules they add and how those rules are communicated. She also suggests having a discussion with the team, asking them why they are circumventing the process. Once everyone's role has been clarified, project managers can then decide which rules, if any, to add.\r\n<span style=\"font-weight: bold;\">Is Agile ALM a good approach for mobile development?</span>\r\nMobile development is faster and more competitive than traditional software development. It has newer technologies and higher-speed application cycles. These qualities could make mobile an excellent candidate for Agile ALM, but only if the methodology is amended to accommodate the challenges inherent in a more restrictive development process. In an article on mobile ALM, site editor James Denman suggested an ALM approach that focuses on smaller pieces of software and authenticates results as each part is finished. That way, teams can quickly discern whether the app will effectively serve its purpose or if it needs to be taken in a different direction.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Agile_Application_Life_Cycle_Management_Software.png","alias":"agile-application-life-cycle-management-software"},"397":{"id":397,"title":"Mobile Testing","description":" Mobile application testing is the process through which applications are tested for required quality, functionality, compatibility, usability, performance and other characteristics.\r\nIt includes a broad range of application testing and evaluation techniques that encompasses both standard software testing and mobile-platform-specific testing procedures.\r\nMobile application testing is typically performed by mobile application developers after a mobile application is developed or before it is released to consumers. Typically, the key objectives of mobile application testing are:\r\n<span style=\"font-style: italic;\">Hardware compatibility and functionality</span> - The mobile application’s response to a mobile device's physical input and interaction with components.

It is a continuous process throughout a project. A requirement is a capability to which a project outcome (product or service) should conform.\r\nThe purpose of requirements management is to ensure that an organization documents, verifies, and meets the needs and expectations of its customers and internal or external stakeholders. Requirements management begins with the analysis and elicitation of the objectives and constraints of the organization. Requirements management further includes supporting planning for requirements, integrating requirements and the organization for working with them (attributes for requirements), as well as relationships with other information delivering against requirements, and changes for these.\r\nThe traceability thus established is used in managing requirements to report back fulfilment of company and stakeholder interests in terms of compliance, completeness, coverage, and consistency. Traceabilities also support change management as part of requirements management in understanding the impacts of changes through requirements or other related elements (e.g., functional impacts through relations to functional architecture), and facilitating introducing these changes.\r\nRequirements management involves communication between the project team members and stakeholders, and adjustment to requirements changes throughout the course of the project. To prevent one class of requirements from overriding another, constant communication among members of the development team is critical. For example, in software development for internal applications, the business has such strong needs that it may ignore user requirements, or believe that in creating use cases, the user requirements are being taken care of.\r\nRequirements traceability is concerned with documenting the life of a requirement. It should be possible to trace back to the origin of each requirement and every change made to the requirement should therefore be documented in order to achieve traceability. Even the use of the requirement after the implemented features have been deployed and used should be traceable.\r\nRequirements come from different sources, like the business person ordering the product, the marketing manager and the actual user. These people all have different requirements for the product. Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation. This can, for example, be used during the development process to prioritize the requirement, determining how valuable the requirement is to a specific user. It can also be used after the deployment when user studies show that a feature is not used, to see why it was required in the first place.","materialsDescription":"<span style=\"font-weight: bold; \">Requirements activities</span>\r\nAt each stage in a development process, there are key requirements management activities and methods. To illustrate, consider a standard five-phase development process with Investigation, Feasibility, Design, Construction, and Test, and Release stages.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Investigation</span></span>\r\nIn Investigation, the first three classes of requirements are gathered from the users, from the business, and from the development team. In each area, similar questions are asked; what are the goals, what are the constraints, what are the current tools or processes in place, and so on. Only when these requirements are well understood can functional requirements be developed.\r\nIn the common case, requirements cannot be fully defined at the beginning of the project. Some requirements will change, either because they simply weren’t extracted, or because internal or external forces at work affect the project in mid-cycle.\r\nThe deliverable from the Investigation stage is a requirements document that has been approved by all members of the team. Later, in the thick of development, this document will be critical in preventing scope creep or unnecessary changes. As the system develops, each new feature opens a world of new possibilities, so the requirements specification anchors the team to the original vision and permits a controlled discussion of scope change.\r\nWhile many organizations still use only documents to manage requirements, others manage their requirements baselines using software tools. These tools allow requirements to be managed in a database, and usually have functions to automate traceability (e.g., by allowing electronic links to be created between parent and child requirements, or between test cases and requirements), electronic baseline creation, version control, and change management. Usually, such tools contain an export function that allows a specification document to be created by exporting the requirements data into a standard document application.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Feasibility</span></span>\r\nIn the Feasibility stage, the costs of the requirements are determined. For user requirements, the current cost of work is compared to the future projected costs once the new system is in place. Questions such as these are asked: “What are data entry errors costing us now?” Or “What is the cost of scrap due to operator error with the current interface?” Actually, the need for the new tool is often recognized as these questions come to the attention of financial people in the organization.\r\nBusiness costs would include, “What department has the budget for this?” “What is the expected rate of return on the new product in the marketplace?” “What’s the internal rate of return in reducing the costs of training and support if we make a new, easier-to-use system?”\r\nTechnical costs are related to software development costs and hardware costs. “Do we have the right people to create the tool?” “Do we need new equipment to support expanded software roles?” This last question is an important type. The team must inquire into whether the newest automated tools will add sufficient processing power to shift some of the burdens from the user to the system in order to save people time.\r\nThe question also points out a fundamental point about requirements management. A human and a tool form a system, and this realization is especially important if the tool is a computer or a new application on a computer. The human mind excels in parallel processing and interpretation of trends with insufficient data. The CPU excels in serial processing and accurate mathematical computation. The overarching goal of the requirements management effort for a software project would thus be to make sure the work being automated gets assigned to the proper processor. For instance, “Don’t make the human remember where she is in the interface. Make the interface report the human’s location in the system at all times.” Or “Don’t make the human enter the same data in two screens. Make the system store the data and fill in the second screen as needed.”\r\nThe deliverable from the Feasibility stage is the budget and schedule for the project.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Design</span></span>\r\nAssuming that costs are accurately determined and benefits to be gained are sufficiently large, the project can proceed to the Design stage. In Design, the main requirements management activity is comparing the results of the design against the requirements document to make sure that work is staying in scope.\r\nAgain, flexibility is paramount to success. Here’s a classic story of scope change in mid-stream that actually worked well. Ford auto designers in the early ‘80s were expecting gasoline prices to hit $3.18 per gallon by the end of the decade. Midway through the design of the Ford Taurus, prices had centered to around $1.50 a gallon. The design team decided they could build a larger, more comfortable, and more powerful car if the gas prices stayed low, so they redesigned the car. The Taurus launch set nationwide sales records when the new car came out, primarily because it was so roomy and comfortable to drive.\r\nIn most cases, however, departing from the original requirements to that degree does not work. So the requirements document becomes a critical tool that helps the team make decisions about design changes.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Construction and test</span></span>\r\nIn the construction and testing stage, the main activity of requirements management is to make sure that work and cost stay within schedule and budget, and that the emerging tool does, in fact, meet requirements. A main tool used in this stage is prototype construction and iterative testing. For a software application, the user interface can be created on paper and tested with potential users while the framework of the software is being built. The results of these tests are recorded in a user interface design guide and handed off to the design team when they are ready to develop the interface. This saves time and makes their jobs much easier.\r\nVerification: This effort verifies that the requirement has been implemented correctly. There are 4 methods of verification: analysis, inspection, testing, and demonstration. Numerical software execution results or through-put on a network test, for example, provides analytical evidence that the requirement has been met. Inspection of vendor documentation or spec sheets also verifies requirements. Actually testing or demonstrating the software in a lab environment also verifies the requirements: a test type of verification will occur when test equipment not normally part of the lab (or system under test) is used. Comprehensive test procedures which outline the steps and their expected results clearly identify what is to be seen as a result of performing the step. After the step or set of steps is completed the last step's expected result will call out what has been seen and then identify what requirements or requirements have been verified (identified by number). The requirement number, title, and verbiage are tied together in another location in the test document.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Requirements change management</span></span>\r\nHardly would any software development project be completed without some changes being asked of the project. The changes can stem from changes in the environment in which the finished product is envisaged to be used, business changes, regulation changes, errors in the original definition of requirements, limitations in technology, changes in the security environment and so on. The activities of requirements change management include receiving the change requests from the stakeholders, recording the received change requests, analyzing and determining the desirability and process of implementation, implementation of the change request, quality assurance for the implementation and closing the change request. Then the data of change requests be compiled, analyzed and appropriate metrics are derived and dovetailed into the organizational knowledge repository.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Release</span></span>\r\nRequirements management does not end with product release. From that point on, the data coming in about the application’s acceptability is gathered and fed into the Investigation phase of the next generation or release. Thus the process begins again.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Requirements_Visualization.png","alias":"requirements-visualization-definition-and-management"},"401":{"id":401,"title":"Service-Oriented Architecture and Web Services","description":" Service-oriented architecture (SOA) is a style of software design where services are provided to the other components by application components, through a communication protocol over a network. An SOA service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies.\r\nA service has four properties according to one of many definitions of SOA:\r\n<ul><li>It logically represents a business activity with a specified outcome.</li><li>It is self-contained.</li><li>It is a black box for its consumers, meaning the consumer does not have to be aware of the service's inner workings.</li><li>It may consist of other underlying services.</li></ul>\r\nDifferent services can be used in conjunction to provide the functionality of a large software application,[4] a principle SOA shares with modular programming. Service-oriented architecture integrates distributed, separately maintained and deployed software components. It is enabled by technologies and standards that facilitate components' communication and cooperation over a network, especially over an IP network.\r\nSOA is related to the idea of an application programming interface (API), an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API can be thought of as the service, and the SOA the architecture that allows the service to operate.","materialsDescription":" <span style=\"font-weight: bold;\">What is Service-Oriented Architecture?</span>\r\nService-oriented architecture (SOA) is a software architecture style that supports and distributes application components that incorporates discovery, data mapping, security and more.

Service-oriented architecture makes it easier for software components to work with each other over multiple networks.\r\nA service-oriented architecture is implemented with web services (based on WSDL and SOAP), to be more accessible over standard internet protocols that are on independent platforms and programming languages.\r\nService-oriented architecture has 3 major objectives all of which focus on parts of the application cycle:\r\n<ol><li>Structure process and software components as services – making it easier for software developers to create applications in a consistent way.</li><li>Provide a way to publish available services (functionality and input/output requirements) – allowing developers to easily incorporate them into applications.</li><li>Control the usage of these services for security purposes – mainly around the components within the architecture, and securing the connections between those components.</li></ol>\r\nMicroservices architecture software is largely an updated implementation of service-oriented architecture (SOA).

Software requirements are classified as either functional or non-functional.\r\nFunctional requirements specify what the software should do. Functional requirements could be calculations, technical details, data manipulation, and processing, or any other specific function that defines what an application is meant to accomplish.\r\nNon-functional requirements specify how the system should work. Also known as “quality attributes” non-functional requirements include things like disaster recovery, portability, privacy, security, supportability, and usability.\r\nNote that most factors indicating software quality fit into the non-functional requirements category. And, while it’s obviously important that software does what it’s built to do, this is the bare minimum you would expect from any application.\r\nBelow are some examples of test metrics and methods for measuring the important aspects of software quality. Efficient measuring and testing of your software for quality is the only way to maximize the chances of releasing high-quality software in today’s fast-paced development environments.\r\nYou can measure reliability by counting the number of high priority bugs found in production. You can also use load testing, which assesses how well the software functions under ordinary conditions of use. It’s important to note that “ordinary conditions of use” can vary between low loads and high loads—the point is that such environments are expected.\r\nLoad testing is also useful for measuring performance efficiency. Stress testing is an important variation on load testing used to determine the maximum operating capacity of an application.\r\nStress testing is conducted by inundating software with requests far exceeding its normal and expected patterns of use to determine how far a system can be pushed before it breaks. With stress testing, you get insight into the recoverability of the software when it breaks—ideally, a system that fails should have a smooth recovery.\r\nYou can measure security by assessing how long it takes to patch or fix software vulnerabilities. You can also check actual security incidents from previous software versions, including whether the system was breached and if any breaches caused downtime for users. All previous security issues should, of course, be addressed in future releases.\r\nCounting the number of lines of code is a simple measure of maintainability—software with more lines of code is harder to maintain, meaning changes are more likely to lead to errors.\r\nThere are several detailed test metrics used to check the complexity of code, such as cyclomatic complexity, which counts the amount of linearly independent paths through a program’s source code.\r\nYou can check the rate of delivery by counting the number of software releases. Another measure is the number of “stories” or user requirements shipped to the user.\r\nYou can test the GUI to make sure it’s simple and not frustrating for end-users. The problem is that GUI testing is complex and time-consuming – there are many possible GUI operations and sequences that require testing in most software.

Unlike standalone apps, an enterprise mobile app development services a comprehensive, long-term approach to deploying mobility. Cross-platform considerations are one big driver behind using MEAPs. For example, a company can use an enterprise mobile app development to develop the mobile application once and deploy it to a variety of mobile devices (including smart phones, tablets, notebooks and ruggedized handhelds) with no changes to the underlying business logic.\r\nPlatform applications are best for companies that wish to deploy multiple applications on a single infrastructure, scaled to the size of their current mobile field force and available in an online and offline mode. Enterprise mobile app platform provides higher level languages and easy development templates to simplify and speed the mobile application development timeframe, requiring less programming knowledge for mobile business application deployment.\r\nThere are many advantages associated with enterprise mobile application development platform. First of all, it can be run on the cloud. Without maintaining separate sets of code, mobile enterprise application platforms can support multiple types of operating systems and mobile devices. This means a company can deploy a mobile application to different mobile devices with the help of mobile enterprise application platforms without having to worry about compatibility. As most enterprise mobile development platforms have a tool set for modifications, creation of custom app extensions is quite easy and convenient. Enterprise mobile application platforms can centrally manage mobile applications and can also help in integration with multiple server data sources.","materialsDescription":"<h1 class=\"align-center\">What are the benefits of enterprise mobile app platform? </h1>\r\n<ul><li>Create apps and complex forms for any type of mobile device and OS without having to maintain separate sets of code.</li><li>Create tailor-made apps for specific user groups, giving them exactly what they need; usually, a mash-up of reading/writing access to your backend systems, publicly available web services and device features such as camera, GPS, sign-on screen, etc.</li><li>Requires basic and limited coding skills e.g. HTML and CSS.</li><li>Allows a high degree of re-use of the code and interactions developed.</li><li>Provide the offline capability for mobile users in areas without WiFi or cellular coverage.</li><li>Once the platform is integrated into the important back-end systems, creating new apps and forms can be done in hours rather than weeks or months.</li><li>Enterprise mobile application development services can be run on the cloud and purchased on a subscription basis.</li></ul>\r\n<h1 class=\"align-center\">Pros and cons of MEAP</h1>\r\nAlong with the benefits described above, a mobile enterprise application platform extends beyond fourth-generation language (4GL) tools for app development to use a graphical environment and dedicated script language.

For ease of IT management, some MEAP products can run as a cloud service.\r\nA MEAP, like any technology, comes with challenges. The initial investment is high - it's expensive to begin with, though the total cost of ownership (TCO) goes down with use over time - and it requires IT to perform additional tasks such as updating content, securing data, maintaining applications with updates and managing user authentication.\r\n<h1 class=\"align-center\">Important features</h1>\r\nIn general, a MEAP has two important features:\r\n<ul><li>A mobile application development environment and back-end web services to manage those mobile applications and link them to enterprise applications and databases.</li><li>A centralized management component that enables an administrator to control which users can access an application and what enterprise databases that application can pull data from.</li></ul>\r\nSometimes, organizations will use a mobile enterprise application platform in conjunction with enterprise mobility management (EMM) or mobile device management (MDM).

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"},"598":{"id":598,"title":"Mobile Website Development","description":" Today, virtually no company can effectively conduct its business without having its own website.

For a long time, Windows was the dominating operating system of the nineties.\r\nWhy Should You Use Mac OS X in App Development? A reason for this system’s stagnation in progress is the brand’s fear in offending its corporate clients; therefore every tech change has to be introduced painfully slowly so as to be assimilated by its clients.\r\nApple, on the other hand, has slowly crept up and overtaken Windows and other operating systems primarily because they are not afraid of taking giant leaps. Their “it’s our way or the high way” approach to their operating system has enabled them to make significant improvements in their software, which other operating systems are almost incapable of attaining.\r\nMAC OS X software is essentially a two-layered system. Its impressive GUI sits on top of a UNIX core, and UNIX is notorious for its impressive security features. UNIX makes it’s nearly impossible to install a Trojan or a virus to the system unless the user gives it root access to the system by essentially typing in the admin password into the system.\r\nThe beauty of MAC OS X built-in firewall is that it operates out the box, while at the same time being highly flexible. While MAC users should ideally remain vigilant about foreign files and consequentially never allow them into the system by giving them an admin pass, they then do not need special software to block out these viruses.\r\nMAC OS interface is simple, you can pin as many apps as possible to dock at the bottom of your screen, plus they are always available to you. Besides this, you can run multiple desktops, make use of your iCloud chain to decipher your credit card information, share various files wirelessly through Airdrop, and still monitor the operating system via a set of in-built high-grade utility tools.\r\nThe system also has a rapid start-up resume time. All this is essentially made possible by MAC OS powerful stability. Even though systemic degradation is expected over time, as is the case with just about every operating system, the rate is significantly reduced on MAC products and freezing and crashing are not a common everyday occurrence as is the case with a few operating systems.\r\nMAC’s impressive reliability can be primarily attributed to the fact that the operating system was built from the ground up. Apple essentially controls the production of its software and hardware products from start to finish, and so every part of the system is designed and tested out to work cohesively together.\r\nThose who complain that Apple forces its consumers to use its proprietary software couldn’t be more misguided. MAC OS automatically recognizes and works well with other Apple products including iPads, iPhones, etc.","materialsDescription":"<span style=\"font-weight: bold;\">What is Mac OS X?</span>\r\nMac OS X is an operating system created by Apple for Mac computers (the first version was introduced in 2001), which replaced the then outdated Mac OS 9.\r\nThis is a POSIX-compatible system, that is, all Unix operations can be performed in it. Built on the basis of the XNU core with the Aqua graphical interface.\r\nStarting with version 10.8 it is called OS X.\r\n<span style=\"font-weight: bold; \">What are the advantages of macOS?</span>\r\n<span style=\"font-style: italic; \">Fewer virus attacks:</span>\r\nAs macOS is the second most used operating system and has fewer active users so it has fewer virus attacks also. The other reason for virus safety is its UNIX relationship which is more secure than Windows OS.\r\n<span style=\"font-style: italic; \">Good customer support:</span>\r\nMac users get a good response from their support team as compared to other operating systems. Apple has skilled engineers which help the user in fixing the issues in their hardware and software.\r\n<span style=\"font-style: italic; \">Similar GUI for all the products:</span>\r\nmacOS has the same graphical user interface (GUI) as found in other Apple products like iPhone and tablets. Users feel comfortable in using macOS if they shifted from other Apple products.\r\n<span style=\"font-style: italic; \">Performance and long life:</span>\r\nAs Apple makes both hardware and software so it’s hardware communication is very efficient and it improves performance. The operating system and hardware work great. Apple computer has a longer life than other computers. The battery timing of mac laptops is also longer.\r\n<span style=\"font-style: italic; \">Default apps:</span>\r\nIf you install Windows then it comes with pre-installed apps that slow down your computer e.g. Onedrive slows your computer. But this is not the case with macOS, it comes with powerful apps which don’t affect the performance of your system. Some of the pre-installed apps of macOS are iPhoto and iMovie.\r\n<span style=\"font-style: italic; \">Support NTFS and FAT:</span>\r\nmacOS support Windows file system formats including both NTFS and FAT.\r\n<span style=\"font-style: italic; \">Can run Windows:</span>\r\nYou can run the Windows operating system if you have macOS installed by using Bootcamp or parallels software.\r\n<span style=\"font-weight: bold; \">What are the disadvantages of macOS?</span>\r\n<span style=\"font-style: italic; \">Expensive:</span>\r\nThe minimum cost of a Mac PC is higher than $1000. You can get a good Windows PC at $1000 with more hardware specifications.\r\n<span style=\"font-style: italic; \">Fewer games and software:</span>\r\nMost game developers prefer to make games for the Windows OS because they have more percentages of users. Mac users have fewer games available. Also, mac computers have low graphics capability to run high graphics games. There is some software that is available for Windows and not available for mac users e.g. adobe premiere pro etc.\r\n<span style=\"font-style: italic; \">No hardware customization:</span>\r\nIf you buy any Mac computer/laptop then you cannot change its hardware parts like processor, graphics card, etc. For some mac computers, you can change hardware and RAM but it is not for all mac computers. It is also not possible to change other hardware accessories like internal computer parts, the only choice you have is to buy a new mac computer. On every major release of your operating system you have to change your computer else 50% of your operating system features not work.\r\n<span style=\"font-style: italic; \">Windows cannot read the macOS file system:</span>\r\nmacOS can read NTFS and FAT Windows format but Windows cannot read the macOS file system.

It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client-server web applications, with a reported 9 million developers.\r\nJava was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1995 as a core component of Sun Microsystems' Java platform. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GNU General Public License. Meanwhile, others have developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets).\r\nThe latest versions are Java 13, released in September 2019, and Java 11, a currently supported long-term support (LTS) version, released on September 25, 2018; Oracle released for the legacy Java 8 LTS the last free public update in January 2019 for commercial use, while it will otherwise still support Java 8 with public updates for personal use up to at least December 2020. Oracle (and others) highly recommend uninstalling older versions of Java because of serious risks due to unresolved security issues. Since Java 9 (and 10 and 12) is no longer supported, Oracle advises its users to immediately transition to the latest version (currently Java 13) or an LTS release.","materialsDescription":"<span style=\"font-weight: bold; \">What is Java technology and what is its application?</span>\r\nJava is a programming language and computing platform that was first launched by Sun Microsystems in 1995. There are many applications and websites that do not work when Java is not installed, and the number of such websites and applications is increasing every day.

Nevertheless, the speed of execution of programs written in Java has been significantly improved with the release of the so-called JIT compiler in 1997-1998. in version 1.1, in addition to other language features to support better code analysis (such as inner classes, StringBuffer class, simplified logic calculations, and so on). In addition, the Java virtual machine was optimized - since 2000, the HotSpot virtual machine has been used for this. As of February 2012, Java 7 code is approximately 1.8 times slower than C code.\r\nSome platforms offer hardware runtime support for Java.

It is therefore possible to code C++ in a &quot;C style&quot; or &quot;object-oriented style.&quot; In certain scenarios, it can be coded in either way and is thus an effective example of a hybrid language.\r\nC++ is considered to be an intermediate-level language, as it encapsulates both high- and low-level language features. Initially, the language was called &quot;C with classes&quot; as it had all the properties of the C language with an additional concept of &quot;classes.&quot; However, it was renamed C++ in 1983.\r\nC++ is one of the most popular languages primarily utilized with system/application software, drivers, client-server applications and embedded firmware.\r\nThe main highlight of C++ is a collection of predefined classes, which are data types that can be instantiated multiple times. The language also facilitates declaration of user-defined classes. Classes can further accommodate member functions to implement specific functionality. Multiple objects of a particular class can be defined to implement the functions within the class. Objects can be defined as instances created at run time. These classes can also be inherited by other new classes which take in the public and protected functionalities by default.\r\nC++ includes several operators such as comparison, arithmetic, bit manipulation and logical operators. One of the most attractive features of C++ is that it enables the overloading of certain operators such as addition.\r\nA few of the essential concepts within the C++ programming language include polymorphism, virtual and friend functions, templates, namespaces and pointers.","materialsDescription":"<span style=\"font-weight: bold; \"> Bjarne Stroustrup's FAQ</span>\r\n<span style=\"font-weight: bold; \">C is better than C++ for small projects, right?</span>\r\nNot in my opinion. I never saw a project for which C was better than C++ for any reason but the lack of a good C++ compiler.\r\n<span style=\"font-weight: bold; \">Is C a subset of C++?</span>\r\nIn the strict mathematical sense, C isn't a subset of C++. There are programs that are valid C but not valid C++ and even a few ways of writing code that has a different meaning in C and C++. However, C++ supports every programming technique supported by C. Every C program can be written in essentially the same way in C++ with the same run-time and space efficiency. It is not uncommon to be able to convert tens of thousands of lines of ANSI C to C-style C++ in a few hours. Thus, C++ is as much a superset of ANSI C as ANSI C is a superset of K&amp;R C and much as ISO C++ is a superset of C++ as it existed in 1985.\r\n<span style=\"font-weight: bold; \">What is the difference between C and C++?</span>\r\nC++ is a direct descendant of C that retains almost all of C as a subset. C++ provides stronger type checking than C and directly supports a wider range of programming styles than C. C++ is &quot;a better C&quot; in the sense that it supports the styles of programming done using C with better type checking and more notational support (without loss of efficiency). In the same sense, ANSI C is a better C than K&amp;R C. In addition, C++ supports data abstraction, object-oriented programming, and generic programming (see my books).\r\nI have never seen a program that could be expressed better in C than in C++ (and I don't think such a program could exist - every construct in C has an obvious C++ equivalent). However, there still exist a few environments where the support for C++ is so weak that there is an advantage to using C instead.\r\n<span style=\"font-weight: bold; \">Do you really think that C and C++ could be merged into a single language?</span>\r\nI think that it would be a very good thing for the C/C++ community if they were. That is, if the C/C++ incompatibilities were systematically and completely eliminated and that future evolution was organized so as to prevent new incompatibilities from emerging. Whether that's possible is another matter.\r\nMy basic point is that the current C/C++ incompatibilities are &quot;accidents of history&quot; that have no fundamental reasons behind them (though they all &quot;looked like a good idea at the time&quot; to some competent and well-meaning people). The C/C++ incompatibilities provide no benefits to the community at large, cause serious problems to a large section of the C/C++ community, and could - with great difficulty - be eliminated.\r\nFor a far more detailed presentation of my views on C/C++ compatibility, see the series of papers I wrote about this:\r\n<ul><li>B. Stroustrup: C and C++: Case Studies in Compatibility. The C/C++ Users Journal. September 2002.</li><li>B. Stroustrup: C and C++: A Case for Compatibility. The C/C++ Users Journal. August 2002.</li><li>B. Stroustrup: C and C++: Siblings. The C/C++ Users Journal. July 2002.</li><li>B. Stroustrup: Sibling rivalry: C and C++. AT&amp;T Labs - Research Technical Report. TD-54MQZY. January 2002. </li></ul>\r\nI imagine that if incompatibilities were eliminated (by making changes to both C and C++), there would still be entities called C and C++, but then C really would be defined as a subset of C++.\r\n<span style=\"font-weight: bold; \">Why did you make C++ (almost) compatible with C?</span>\r\nI wanted C++ to be compatible with a complete language with sufficient performance and flexibility for even the most demanding systems programming.\r\nAt the time, I considered C the best systems programming language available. That was not as obvious then (1979) as it later became, but I had experts such as Dennis Ritchie, Steve Johnson, Sandy Fraser, Greg Chesson, Doug McIlroy, and Brian Kernighan down the corridor from whom I could learn and get feedback. Without their help and advice, and without C, C++ would have been stillborn.\r\nContrary to repeated rumors, I was never told that I had to use C; nor was I ever told not to use C. In fact, the first C++ manual grew from troff source of the C manual that Dennis gave me. Many new languages were designed at Bell labs; in &quot;Research&quot; at least, there were no rules enforcing language bigotry.\r\n<span style=\"font-weight: bold; \">What do you think of C/C++?</span>\r\nNo that's not really a question I often get. In that sense, it is the only &quot;fake FAQ&quot; in this FAQ. However, it ought to be a FAQ because people use &quot;C/C++&quot; as if it meant something specific and as if they knew what it meant, leading to much confusion and misery. People should ask &quot;What is C/C++?&quot; and then on reflection stop using the term. It does harm.\r\nThere is no language called &quot;C/C++&quot;. The phrase is usually used by people who don't have a clue about programming (e.g. HR personnel and poor managers). Alternatively, it's used by people who simple do not know C++ (and often not C either). When used by programmers, it typically indicates a &quot;C++ is C with a few useful and a lot of useless complicated features added&quot; attitude. Often, that is the point of view of people who like to write their own strings and hash tables with little knowledge of the standard library beyond printf and memcpy. There are people who stick to a restricted subset of C++ for perfectly good reasons, but they (as far as I have noticed) are not the people who say &quot;C/C++&quot;.\r\nI use C/C++ only in phrases such as &quot;C/C++ compatibility&quot; and &quot;C/C++ community&quot;.\r\n<span style=\"font-weight: bold;\">When was C++ invented?</span>\r\nI started work on what became C++ in 1979. The initial version was called &quot;C with Classes&quot;. The first version of C++ was used internally in AT&amp;T in August 1983. The name &quot;C++&quot; was used late that year. The first commercial implementation was released October 1985 at the same time as the publication of the 1st edition of The C++ Programming Language. Templates and exception handling were included later in the 1980's and documented in The Annotated C++ Reference Manual and The C++ Programming Language (2rd Edition). The first ISO C++ standard was C++98 as described in The C++ Programming Language (3rd Edition).\r\nThe current definition of C++ The 2011 ISO C++ Standard described in The C++ Programming Language (4th Edition).\r\nYou can find a more complete timeline and more detailed explanations in The Design and Evolution of C++ and A History of C++: 1979-1991 and Evolving a language in and for the real world: C++ 19.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_C_C_Development.png","alias":"cc-development"},"609":{"id":609,"title":".Net Development","description":" .NET Framework is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library named Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (in contrast to a hardware environment) named Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called &quot;managed code&quot;. FCL and CLR together constitute the .NET Framework.\r\nFCL provides user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. Programmers produce software by combining their source code with .NET Framework and other libraries. The framework is intended to be used by most new applications created for the Windows platform. Microsoft also produces an integrated development environment largely for .NET software called Visual Studio.\r\n.NET Framework began as proprietary software, although the firm worked to standardize the software stack almost immediately, even before its first release. Despite the standardization efforts, developers, mainly those in the free and open-source software communities, expressed their unease with the selected terms and the prospects of any free and open-source implementation, especially regarding software patents. Since then, Microsoft has changed .NET development to more closely follow a contemporary model of a community-developed software project, including issuing an update to its patent promising to address the concerns.\r\n.NET Framework led to a family of .NET platforms targeting mobile computing, embedded devices, alternative operating systems, and web browser plug-ins. A reduced version of the framework, .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. .NET Micro Framework is targeted at very resource-constrained embedded devices. Silverlight was available as a web browser plugin. Mono is available for many operating systems and is customized into popular smartphone operating systems (Android and iOS) and game engines. .NET Core targets the Universal Windows Platform (UWP), and cross-platform and cloud computing workloads.","materialsDescription":"When Microsoft formally introduced its .NET strategy in mid-2000, analysts were confused about how the company would pull off such a massive platform shift. Over two years later, they're still wondering. But .NET isn't vaporware, and it's not a pipe dream. In fact, .NET is happening today.\r\n<span style=\"font-weight: bold; \">What is .NET?</span>\r\nActually, .NET is many things, but primarily it's a marketing term for a set of products and technologies that Microsoft is creating to move personal and enterprise computing beyond the PC desktop and into a distributed Internet-based environment. So .NET--which was originally called Next Generation Windows Services (NGWS)--is also a platform, one that Microsoft sees as the successor to Windows. The .NET platform is based on Web services which are, in turn, defined by a language called XML.\r\n<span style=\"font-weight: bold; \">What is XML?</span>\r\nXML--the eXtensible Markup Language--is a self-descriptive, data definition language. It's structure is similar to HTML, the language of the Web, but it's far more powerful because it's not limited to a static list of language constructs (&quot;tags&quot;) that the language's authors supply. Instead, XML is extensible and dynamic: Programmers can define new types of data using XML and then describe that data so that others will know how to use it.\r\n<span style=\"font-weight: bold; \">What are Web services?</span>\r\nWeb services are functions exposed by server-side applications. They are programmable units that other applications (and Web services) can access over the Internet.\r\n<span style=\"font-weight: bold; \">Does .NET require Windows?</span>\r\nTechnically, no, but realistically, yes. It's possible the .NET platform could be ported to other operating systems, such as Linux, FreeBSD, the Macintosh, or whatever, and indeed, some work is being done now in this area. However, .NET very much requires Windows today, on both the server and the client. One might say that .NET and Windows have a symbiotic relationship going forward.\r\n<span style=\"font-weight: bold; \">Is .NET is being ported to Linux?</span>\r\nYes. A company called Ximian is porting the standards-based parts of .NET to Linux as you read this, and the work is amazingly far along. Code-named Mono, this project seeks to bring the C# programming language, the Common Language Runtime (CLR, see below), and other .NET features to Linux.\r\nOn a related note, Microsoft has contracted Corel (makers of CorelDRAW and Word Perfect) to port .NET to FreeBSD.\r\n<span style=\"font-weight: bold; \">Isn't .NET just another name for COM, COM+, Windows DNA, or some other previous Windows technology?</span>\r\nActually, no. Microsoft spent considerable time and effort developing and promoting a set of Windows technologies that was at various times called OLE, COM, COM+, and Windows DNA (Distributed InterNet Architecture) but .NET is not the next iteration. Windows DNA, which was the final umbrella term for this set of technologies, was based around a concept where Windows-based software components could expose their services for other local and remote Windows software components. But though this sounds passingly similar to .NET, Windows DNA is very much based on proprietary Windows technologies. By comparison, .NET is based on open standards (XML and various related technologies), so it will be much easier for other vendors to adopt the platform and write compatible software. So we can eventually expect to see .NET clients and servers on platforms other than Windows.\r\n<span style=\"font-weight: bold; \">So what technologies are part of .NET?</span>\r\n.NET is comprised of several related technologies, including:\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Framework</span></span> - A runtime environment and set of standard services which .NET capable applications and services can utilize. Implemented as a code library, the .NET Framework includes the Common Language Runtime (CLR), the .NET run-time environment; ASP .NET, a Web applications platform; and ADO .NET, for data store access.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Compact Framework</span></span> - A subset of the .NET Framework designed for Pocket PCs, Microsoft Smart Phones, and other Windows CE .NET-based mobile devices.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">MSN consumer services</span></span> - Microsoft will use its consumer-oriented MSN online service to expose Web services to individuals. The current version, MSN 8, includes the .NET Passport's authentication services, email, address book, calendaring and tasks, and other similar services.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Enterprise Servers</span></span> - An extensive set of Microsoft server software that runs on Windows servers, including Application Server, BizTalk Server, Exchange Server, Host Integration Server, Internet Security and Acceleration Server, SQL Server, and many others. Microsoft is currently shipping many such server products, but they are all based on Windows DNA currently, not .NET. Future server products--beginning with Windows .NET Server 2003, due in April 2003--will actually be based on .NET technologies for the first time.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Visual Studio .NET</span></span> - Microsoft's .NET development environment, with support for languages such as Visual Basic .NET, Visual C++ .NET, Visual C# .NET, and Visual J#, which all target the .NET Framework. Other vendors can add other language capabilities to Visual Studio .NET, and the suite can be used to target a wide range of applications and services, including .NET Web services, Windows applications, and Web applications. Note that Visual Studio .NET is not required to create .NET applications and services: Developers can download the .NET Framework for free; this download includes compilers for Visual Basic .NET, Visual C++ .NET and Visual C# .NET.\r\n<span style=\"font-weight: bold;\">OK, so what's the point? How does this make my life better?</span>\r\nWith apologies to Microsoft for stealing the term, .NET enables a better PC ecosystem. That is, by making life easier for everyone involved with PCs, the benefits are cross-pollinated. Here's how .NET makes life easier on various groups:\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Programmers</span></span> - Because developers now have a consistent, language-neutral programming environment, they can create better applications and services more quickly. And because .NET encompasses such a wider range of functionality, those applications and services can be connected to back-end services via the Internet, offering better, and more exciting functionality.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">IT administrators</span></span> - Because .NET applications and services do away with the &quot;DLL Hell&quot; found in previous Windows applications, they are amazingly easy to distribute and install.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">End users</span></span> - For the reasons listed above, and many others, a new generation of .NET applications and services will provide new types of connected functionality. Access your email from anywhere. Pay for products online without typing in your credit card information. Access weather, traffic, music, and other personal information from a variety of devices, from anywhere in the world.

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.

Developed in 1998–2001 by a group of engineers under the leadership of Anders Hejlsberg at Microsoft as the main language for developing applications for the Microsoft .NET platform. The compiler with C# is included in the standard installation of the .NET itself, so programs on it can be created and compiled even without tools like Visual Studio.\r\nC# refers to a family of languages ​​with a C-like syntax, of which its syntax is closest to C++ and Java. The language has strict static typing, supports polymorphism, operator overloading, pointers to member functions of classes, attributes, events, properties, exceptions, comments in XML format. Having taken a lot from their predecessors - C++, Java, Delphi, Modula and Smalltalk - C#, based on the practice of using them, excludes some models that have proven to be problematic when developing software systems: thus, C # does not support multiple class inheritance (unlike C ++).\r\nC# was developed as an application level programming language for the CLR and, as such, depends primarily on the capabilities of the CLR itself. This concerns, first of all, the C # type system, which reflects FCL. The presence or absence of certain expressive features of the language is dictated by whether a particular language feature can be translated into the corresponding CLR constructs. So, with the development of the CLR from version 1.1 to 2.0, C # itself was significantly enriched; similar interaction should be expected in the future. (However, this pattern was broken with the release of C # 3.0, which are language extensions that do not rely on .NET platform extensions.) The CLR provides C #, like all other .NET-oriented languages, many of the features that the “classical” programming languages ​​lack. For example, garbage collection is not implemented in C # itself, but the CLR is done for programs written in C # just like it is done for programs on VB.NET, J #, and others.","materialsDescription":"<span style=\"font-weight: bold;\"> Why is it necessary to study the C# programming language?</span>\r\n<span style=\"font-weight: bold;\">Reason # 1. Language program C# develops.</span>\r\nNew programming languages ​​appear annually. And the main demand is expanding and progressing. Since the C# programming language was created and accompanied by Microsoft, this technological “hippopotamus” periodically makes improvable with the addition of useful functions in C #, and you can be sure that it will perform many, many iterations ... Also, billions of lines of code are written all over the world not only under Microsoft, so the work is foreseen to everyone who wants to learn the C # programming language.\r\n<span style=\"font-weight: bold;\">Reason # 2. Your bright future with C#.</span>\r\nThis item smoothly continues the previous one. According to the ratings of the domestic DOU, it is clear that the C# programming language in Ukraine is in 3rd place in 2018 among programming languages. And in the world charts on the 4th place by PYPL PopularitY of Programming Language is a rating using Google Trends.\r\n<span style=\"font-weight: bold;\">Reason # 3. The possibility of greater profits.</span>\r\nOf course, this statement should be evaluated relatively by comparison. Today they like to say: “A programmer’s working time is more expensive than additional memory or a more powerful computer processor. It is recommended to choose more modern tools that don’t over-brain a programmer.”\r\nOn the other hand, when they talk about C#, they always mean speed and large, valuable, serious projects, even Megaprojects. For example, in C#, the Linux kernel, Unix, libraries, environment, interpreters of many modern programming languages ​​are written.\r\n<span style=\"font-weight: bold;\">Reason # 4. C# has a huge set of use cases.</span>\r\n<ul><li>The C # programming language is mainly used to create corporate software, financial projects, for example, for banks and stock exchanges, in particular, mobile applications, cloud services.</li><li>Compared to Java, C# interacts more easily with code written in other languages. And it is precisely in C# that extensions are often written for other programming languages ​​used as a layer between the C # library and the language, the possibilities of which are planned to be extended for specific purposes.</li><li>A pretty popular blockchain in C#.</li><li>C# is widely used in developing games on Unity. Have you ever heard of Unity? Unity is a popular game engine. This means that hundreds of thousands of games, including the most popular, were created using C#.</li><li>C# is good for working with iron, the so-called embedded. Asking what is embedded technology? Embedded system - a specialized computer system or computing device designed to perform a limited number of functions, from Wikipedia: traffic lights, cash registers, vending machines, set-top boxes, test equipment, etc.</li><li>The popular C# programming language is equally good for IoT. Again, what is IoT? IoT (Internet of Things) is a concept of a comprehensive Internet, Internet connection of refrigerators, air conditioners, cars and even sneakers with the aim of providing its owner with greater comfort, and on the other hand increasing their retailers' profits, calculating the amount of what, how much and when availability in warehouses, obtaining certain information about a person and his habits, about the environment.</li><li>Science and its application, for example, conducting complex experimental calculations, cryptography, pattern recognition, and the like.</li></ul>\r\n<span style=\"font-weight: bold;\">Reason # 5. C# is strongly typed, so it is easier for them to master beginners</span>\r\nAs for the comparison of programming languages, it should be noted that the C# programming language is multi-level. This means that it is somewhat similar to English. The C# programming language has strong static typing, supports polymorphism, operator overloading, pointers to member functions of classes, attributes, events, properties, exceptions, comments in XML format. Having adopted a lot from their predecessors - C++, Delphi, Modula, Smalltalk - in C #, relying on the practice of using them, deliberately excluded some models that proved to be problematic when developing software systems in the above-mentioned programming languages.\r\nThe syntax is quite minimalistic - with manual memory management. This is inconvenient for many, but tracking the correctness of functions, understanding the transmission of arguments is closely related to the study of the C# programming language.\r\nSince the syntax of C# is close to C, C++ and Java, then, fluent in C #, you can later learn them in one breath.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_C_Development.png","alias":"c-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.

It makes this CMS (content management system) the second most popular after WordPress.\r\n<span style=\"font-weight: bold; \">What are the key features of Joomla?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Responsive.</span></span> Responsiveness is a “must have” for any up-to-date website. 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. Joomla contact manager enables you to create users in different departments and categories.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Joomla Content Management</span></span>\r\nEven though I’ve heard customers saying Joomla has a longer learning curve, compared to WordPress, it’s so worth it, because with Joomla comes greater flexibility and content combining possibilities.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Joomla Extensions (8000+)</span></span>\r\nJoomla has one of the most powerful extension databases among both CMS and eCommerce platforms.<br />You can find a plugin or module to do almost anything. What is remarkable regarding Joomla extensions - a lot of great plugins and modules are free, while most paid ones come with a free lite version and there is the possibility to upgrade to a premium version whenever you decide to do so.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Front-end Editing</span></span>\r\nI left it till the very end of the guide as it’s my favorite one. That’s what bugs me about WordPress and what cheers me up when working with Joomla - there is no need to go to the admin panel to edit some piece of content.\r\nIf you enabled front-end editing of your site, there will be a gear wheel next to any module and by clicking on it you’ll be able to make changes on the go. It’s a thrill in this bustling world in which we live.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Joomla_Development.png","alias":"joomla-development"},"619":{"id":619,"title":"Drupal Development","description":" Drupal is a content management software.

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.

TYPO3 CMS is an Open Source Enterprise Content Management System with a large global community, backed by the approximately 900 members of the TYPO3 Association.\r\n<span style=\"font-weight: bold; \">Where did the name TYPO3 come from?</span>\r\nTYPO3 creator Kasper Skårhøj remembers it something like this:\r\nBack in the late 1990s, while still working on the initial version of his new CMS, he was looking for a name for the new software. At the time, the name “freestyle” appealed to him, but it posed some problems through its over-association with certain activities, products and trademarks. So the issue of naming stayed on the back burner for want of a better idea.\r\nThen, one Friday evening while he was alone in the office after hours coding, Kasper inadvertently typed an error into the command line of his Linux server and accidentally deleted a whole week work. He recalls that feeling you get of a cold rush through the body, when you realize something dreadful has happened. Slowly he got up, walked to the other end of the room and sat down in the couch looking back across the office at the laptop on his desk.\r\nHe stayed like this for a while, just staring out into the room. Then, after the initial shock had subsided, he walked back, sat down, and began to recreate the lost code. This went surprisingly quickly; as such things do when you have them fully worked out in your head. And it was during this new rush of adrenaline and the satisfaction that all was not actually lost, that he began to put the incident into perspective. The recreated programming was going smoothly and cleanly, which made him wonder how ironic it would be if a typo ended up actually improving the product! It was this thought that first brought up the expression “typo” as a possible name. It seemed to fit especially well because\r\n<ul><li>“typo”, as in typography, had something to do with layout and content and</li><li>“typo”, as in a typing mistake, now had a quirky share in the product’s history.</li></ul>\r\nThe newborn child now had a name.\r\nOriginally there were Typo versions 1, 2 and 2.5. But with the success of version 3, which had branded itself more or less by default, a “3” was eventually appended to the product title itself. Since the launch of “TYPO3 version 4”, TYPO3 has remained as the product name for all future versions. So, TYPO3 it is called … and TYPO3 it will continue to be.\r\n<span style=\"font-weight: bold; \">What is TYPO3?</span>\r\nTYPO3 is a free and open-source Web content management system written in PHP.

CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.\r\nCSS is designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content.\r\nSeparation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering methods, such as on-screen, in print, by voice (via speech-based browser or screen reader), and on Braille-based tactile devices. CSS also has rules for alternate formatting if the content is accessed on a mobile device.\r\nThe name cascading comes from the specified priority scheme to determine which style rule applies if more than one rule matches a particular element. This cascading priority scheme is predictable.\r\nThe CSS specifications are maintained by the World Wide Web Consortium (W3C). Internet media type (MIME type) text/css is registered for use with CSS by RFC 2318 (March 1998). The W3C operates a free CSS validation service for CSS documents.\r\nIn addition to HTML, other markup languages support the use of CSS including XHTML, plain XML, SVG, and XUL.\r\nBefore CSS, nearly all presentational attributes of HTML documents were contained within the HTML markup. All font colors, background styles, element alignments, borders and sizes had to be explicitly described, often repeatedly, within the HTML. CSS lets authors move much of that information to another file, the style sheet, resulting in considerably simpler HTML.","materialsDescription":" <span style=\"font-weight: bold;\">Which is better: plain HTML or HTML with CSS?</span>\r\nMany site developers wonder why you need CSS if you can use plain HTML. Most likely, they only know the development of the site and have a number of gaps in knowledge. The bottom line is that HTML is used to structure the content of a page. And CSS allows you to format this content, make it more attractive to users.\r\nWhen the World Wide Web was created, the developers used only one language - HTML. It was used as a means of outputting structured text. The author had scant functional at his disposal. The maximum that could be done - to designate the title, select the paragraph. Tags were not enough.\r\nIn connection with the development of the Internet, the base of HTML language tags was expanded to allow the appearance of documents to be adjusted. At the same time, the structure remained unchanged.\r\nStructuring tags, for example &lt;table&gt;, began to spread. It was they who were more often chosen to design the pages instead of the structure itself. Some browsers offered their own tags, which only they could reproduce.\r\nThus, users often stumbled upon the message: &quot;To view a page, you need to use browser XXX.&quot;\r\nTo correct the situation and create a single database of tags for formatting was created CSS. He allowed refusing to bind tags to browsers.\r\nUsing HTML with CSS is more convenient than using plain HTML. CSS provides the following benefits:\r\n<ul><li>Designed to the smallest detail.</li><li>Using a single table, you can manage various documents.</li><li>You can customize the page display options for different devices: computer screen, smartphone screen, etc.</li></ul>\r\n<span style=\"font-weight: bold;\">Website Promotion with CSS</span>\r\nThe emergence and development of CSS have made the development of web resources more efficient and effective. Now it’s much easier and more convenient to control the design. Also, using CSS, we managed to reduce the code of the pages, their size. This had a positive impact on the download speed, the indexing also began to pass faster. The use of an adaptive approach allowed us to make a breakthrough in the field of mobile versions of Internet resources.\r\nTo improve the website promotion, experts recommend placing the CSS style sheets in a separate document so as not to increase the amount of code. You can create one or more such files.\r\nPreviously, search engines could not read style sheets, which made it possible to use them in black SEO, for example, to create invisible texts. Now it is better to abandon the use of CSS for other purposes.\r\nCSS has several advantages and allows you to improve the site, making it more attractive to visitors. However, it is important to correctly register all the elements.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_CSS_Development.png","alias":"css-development"},"629":{"id":629,"title":"PHP Development","description":"PHP is a general-purpose programming language originally designed for web development.

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.

Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace. 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.

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.

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.

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.

With Ajax, web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows web pages and, by extension, web applications, to change content dynamically without the need to reload the entire page. In practice, modern implementations commonly utilize JSON instead of XML.\r\nAjax is not a single technology, but rather a group of technologies. HTML and CSS can be used in combination to mark up and style information. The webpage can then be modified by JavaScript to dynamically display—and allow the user to interact with—the new information. The built-in XMLHttpRequest object within JavaScript is commonly used to execute Ajax on webpages allowing websites to load content onto the screen without refreshing the page. Ajax is not a new technology, or different language, just existing technologies used in new ways.\r\nThe term Ajax has come to represent a broad group of Web technologies that can be used to implement a Web application that communicates with a server in the background, without interfering with the current state of the page. In the article that coined the term Ajax, Jesse James Garrett explained that the following technologies are incorporated:\r\n<ul><li>HTML (or XHTML) and CSS for presentation</li><li>The Document Object Model (DOM) for dynamic display of and interaction with data</li><li>JSON or XML for the interchange of data, and XSLT for its manipulation</li><li>The XMLHttpRequest object for asynchronous communication</li><li>JavaScript to bring these technologies together</li></ul>\r\nSince then, however, there have been a number of developments in the technologies used in an Ajax application, and in the definition of the term Ajax itself. XML is no longer required for data interchange and, therefore, XSLT is no longer required for the manipulation of data. JavaScript Object Notation (JSON) is often used as an alternative format for data interchange, although other formats such as preformatted HTML or plain text can also be used. A variety of popular JavaScript libraries, including JQuery, include abstractions to assist in executing Ajax requests.\r\nAsynchronous HTML and HTTP (AHAH) involves using XMLHTTPRequest to retrieve (X)HTML fragments, which are then inserted directly into the Web page.","materialsDescription":" <span style=\"font-weight: bold;\">What Is AJAX?</span>\r\nAJAX is an acronym that stands for Asynchronous JavaScript and XML, and it describes a set of development techniques used for building websites and web applications. According to web developer and Skillcrush WordPress instructor Ann Cascarano, the best way to understand AJAX is to start with identifying its specific purpose in the web development process. AJAX’s core function is to update web content asynchronously (the “A” of AJAX), meaning a user’s web browser doesn’t need to reload an entire web page when only a small portion of content on the page needs to change.\r\nOne of the most ubiquitous examples of asynchronous updating is Google’s “Google Suggest” feature. When you enter a search query into Google’s search bar and the Google website automatically begins offering auto-complete options while you type, that’s AJAX in action. The content on the page changes (in this case, the auto-complete options in the search bar) without having to manually refresh the page (something that would make Google Suggest impractical to use). Features like Google Suggest are a fundamental part of contemporary web browsing, which points to how essential AJAX is in web development. In addition to Google Suggest, Cascarano says that AJAX is commonly used to update features like status and notification bars, online forms, comments sections, and surveys and polls. But what exactly are the “J” and “X” of AJAX and how do they make asynchronous updating possible?\r\n<span style=\"font-weight: bold;\">JavaScript and XML</span>\r\nAs mentioned above, the “J” in AJAX stands for JavaScript. JavaScript is a type of scripting language—coding languages used to automate website processes so web developers don’t have to individually program each instance of the process that appears on a page. In JavaScript’s case, it’s used specifically to create, add, and manage dynamic website content. In other words, after markup languages like HTML and CSS are used to build and display static web features (headers, fonts, paragraphs, etc.), JavaScript is then used to control features that require real time updates while a visitor is viewing a page (think interactive maps, animated graphics, scrolling video, jukeboxes, etc). Since JavaScript is in the business of updating page content without requiring viewers to manually reload entire pages, it’s a critical component for AJAX’s asynchronous updating.\r\nThe “X” in AJAX is XML (Extensible Markup Language). As its name suggests, XML is a markup language, which means it’s in the same family as languages like HTML and CSS. Markup languages are coding languages used to annotate parts of a web document that are intended to give web browsers instructions about how to understand, process, and display a web page, versus the actual text intended to be displayed on the page. While HTML and CSS focus on instructing how page content is displayed (paragraphs, headers, fonts, colors, etc.), XML is used to transfer data stored on the page to the browsers that view it. Individual computer systems are often incompatible with one another and can’t understand or interact with data formatted by a different system. XML allows developers to bypass this obstacle by storing data in plain text format between XML tags. By doing this, XML offers a way of storing, moving, and sharing data that isn’t dependent on a particular software or hardware system (something that’s crucial for the internet, where data needs to be available and understandable across all software and hardware platforms). RSS feeds—subscription web feeds that allow users to access content from blogs and news sources as they are updated in real time—are built with XML and are an example of the language’s practical data-sharing capabilities. But how does XML combine with JavaScript to form AJAX?\r\n<span style=\"font-weight: bold;\">How Does AJAX Work?</span>\r\nAccording to Cascarano, JavaScript and XML combine to make asynchronous updating happen through the use of something called an XMLHttpRequest object. When a user visits a web page designed to make use of AJAX and a prescribed event occurs (the user loads the page, clicks a button, fills out a form, etc.) JavaScript creates an XMLHttpRequest object, which then transfers data in an XML format between a web browser (the program being used to view the website) and a web server (the software or hardware where a website’s data is stored). The XMLHttpRequest object sends a request for updated page data to the web server, the server process the request, a response is created server-side and sent back to the browser, which then uses JavaScript to process the response and display it on the screen as updated content.\r\nTo recap: JavaScript automates the updating process, the request for updated content is formatted in XML to make it universally understandable, and JavaScript again kicks in to refresh the relevant content for the user viewing the page. Cascarano notes that the AJAX technique ignores extraneous page data and only handles requests for updated information and the updated information itself. This is really the heart of AJAX’s effectiveness, making websites and applications that use AJAX faster and more responsive for users.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_AJAX_Development.png","alias":"ajax-development"},"645":{"id":645,"title":"JavaScript development","description":" JavaScript, often abbreviated as JS, is a high-level, just-in-time compiled, object-oriented programming language that conforms to the ECMAScript specification.

JavaScript enables interactive web pages and is an essential part of web applications. The vast majority of websites use it, and major web browsers have a dedicated JavaScript engine to execute it.\r\nAs a multi-paradigm language, JavaScript supports event-driven, functional, and imperative (including object-oriented and prototype-based) programming styles. It has APIs for working with text, arrays, dates, regular expressions, and the DOM, but the language itself does not include any I/O, such as networking, storage, or graphics facilities. It relies upon the host environment in which it is embedded to provide these features.\r\nInitially only implemented client-side in web browsers, JavaScript engines are now embedded in many other types of host software, including server-side in web servers and databases, and in non-web programs such as word processors and PDF software, and in runtime environments that make JavaScript available for writing mobile and desktop applications, including desktop widgets.\r\nThe terms Vanilla JavaScript and Vanilla JS refer to JavaScript not extended by any frameworks or additional libraries. Scripts written in Vanilla JS are plain JavaScript code.\r\nAlthough there are similarities between JavaScript and Java, including language name, syntax, and respective standard libraries, the two languages are distinct and differ greatly in design.

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","alias":"user-interface-development"},"685":{"id":685,"title":"Database Administration","description":" Database administration refers to the whole set of activities performed by a database administrator to ensure that a database is always available as needed. Other closely related tasks and roles are database security, database monitoring and troubleshooting, and planning for future growth.\r\nDatabase administration is an important function in any organization that is dependent on one or more databases.\r\nThe database administrator (DBA) is usually a dedicated role in the IT department for large organizations. However, many smaller companies that cannot afford a full-time DBA usually outsource or contract the role to a specialized vendor, or merge the role with another in the ICT department so that both are performed by one person.\r\nThe primary role of database administration is to ensure maximum up time for the database so that it is always available when needed. This will typically involve proactive periodic monitoring and troubleshooting. This in turn entails some technical skills on the part of the DBA. In addition to in-depth knowledge of the database in question, the DBA will also need knowledge and perhaps training in the platform (database engine and operating system) on which the database runs.\r\nA DBA is typically also responsible for other secondary, but still critically important, tasks and roles. Some of these include:\r\n<ul><li>Database Security: Ensuring that only authorized users have access to the database and fortifying it against any external, unauthorized access.</li><li>Database Tuning: Tweaking any of several parameters to optimize performance, such as server memory allocation, file fragmentation and disk usage.</li><li>Backup and Recovery: It is a DBA's role to ensure that the database has adequate backup and recovery procedures in place to recover from any accidental or deliberate loss of data.</li><li>Producing Reports from Queries: DBAs are frequently called upon to generate reports by writing queries, which are then run against the database.</li></ul>\r\nIt is clear from all the above that the database administration function requires technical training and years of experience. Some companies that offer commercial database products, such as Oracle DB and Microsoft's SQL Server, also offer certifications for their specific products. These industry certifications, such as Oracle Certified Professional (OCP) and Microsoft Certified Database Administrator (MCDBA), go a long way toward assuring organizations that a DBA is indeed thoroughly trained on the product in question. Because most relational database products today use the SQL language, knowledge of SQL commands and syntax is also a valuable asset for today's DBAs.","materialsDescription":" <span style=\"font-weight: bold;\">Data Resource Management</span>\r\nAccording to the Data Management Association (DAMA), data resource management is &quot;the development and execution of architectures, policies, practices and procedures that properly manage the full data lifecycle needs of an enterprise&quot;. Data Resource management may be thought of as a managerial activity that applies information system and other data management tools to the task of managing an organization’s data resource to meet a company’s business needs, and the information they provide to their shareholders. From the perspective of database design, it refers to the development and maintenance of data models to facilitate data sharing between different systems, particularly in a corporate context. Data Resource Management is also concerned with both data quality and compatibility between data models.\r\nSince the beginning of the information age, businesses need all types of data on their business activity. With each data created, when a business transaction is made, need data is created. With these data, new direction is needed that focuses on managing data as a critical resource of the organization to directly support its business activities. The data resource must be managed with the same intensity and formality that other critical resources are managed. Organizations must emphasize the information aspect of information technology, determine the data needed to support the business, and then use appropriate technology to build and maintain a high-quality data resource that provides that support.\r\nData resource quality is a measure of how well the organization's data resource supports the current and the future business information demand of the organization. The data resource cannot support just the current business information demand while sacrificing the future business information demand. It must support both the current and the future business information demand. The ultimate data resource quality is stability across changing business needs and changing technology.\r\nA corporate data resource must be developed within single, organization-wide common data architecture. A data architecture is the science and method of designing and constructing a data resource that is business driven, based on real-world objects and events as perceived by the organization, and implemented into appropriate operating environments. It is the overall structure of a data resource that provides a consistent foundation across organizational boundaries to provide easily identifiable, readily available, high-quality data to support the business information demand.\r\nThe common data architecture is a formal, comprehensive data architecture that provides a common context within which all data at an organization's disposal are understood and integrated. It is subject oriented, meaning that it is built from data subjects that represent business objects and business events in the real world that are of interest to the organization and about which data are captured and maintained.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Database_Administration.png","alias":"database-administration"},"689":{"id":689,"title":"Amazon Web Services","description":"Amazon Web Services (AWS) is a subsidiary of Amazon that provides on-demand cloud computing platforms to individuals, companies and governments, on a metered pay-as-you-go basis. In aggregate, these cloud computing web services provide a set of primitive, abstract technical infrastructure and distributed computing building blocks and tools. One of these services is Amazon Elastic Compute Cloud, which allows users to have at their disposal a virtual cluster of computers, available all the time, through the Internet. AWS's version of virtual computers emulate most of the attributes of a real computer including hardware (CPU(s) &amp; GPU(s) for processing, local/RAM memory, hard-disk/SSD storage); a choice of operating systems; networking; and pre-loaded application software such as web servers, databases, CRM, etc.\r\nThe AWS technology is implemented at server farms throughout the world, and maintained by the Amazon subsidiary. Fees are based on a combination of usage, the hardware/OS/software/networking features chosen by the subscriber, required availability, redundancy, security, and service options. Subscribers can pay for a single virtual AWS computer, a dedicated physical computer, or clusters of either. As part of the subscription agreement, Amazon provides security for subscribers' system. AWS operates from many global geographical regions including 6 in North America.\r\nIn 2017, AWS comprised more than 90 services spanning a wide range including computing, storage, networking, database, analytics, application services, deployment, management, mobile, developer tools, and tools for the Internet of Things. The most popular include Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3). Most services are not exposed directly to end users, but instead offer functionality through APIs for developers to use in their applications. Amazon Web Services' offerings are accessed over HTTP, using the REST architectural style and SOAP protocol.\r\nAmazon markets AWS to subscribers as a way of obtaining large scale computing capacity more quickly and cheaply than building an actual physical server farm. All services are billed based on usage, but each service measures usage in varying ways. As of 2017, AWS owns a dominant 34% of all cloud (IaaS, PaaS) while the next three competitors Microsoft, Google, and IBM have 11%, 8%, 6% respectively according to Synergy Group.","materialsDescription":"<span style=\"font-weight: bold;\">What is &quot;Amazon Web Services&quot; (AWS)?</span>\r\nWith Amazon Web Services (AWS), organizations can flexibly deploy storage space and computing capacity into Amazon's data centers without having to maintain their own hardware. A big advantage is that the infrastructure covers all dimensions for cloud computing. Whether it's video sharing, high-resolution photos, print data, or text documents, AWS can deliver IT resources on-demand, over the Internet, at a cost-per-use basis. The service exists since 2006 as a wholly owned subsidiary of Amazon Inc. The idea arose from the extensive experience with Amazon.com and the own need for platforms for web services in the cloud.\r\n<span style=\"font-weight: bold;\">What is Cloud Computing?</span>\r\nCloud Computing is a service that gives you access to expert-managed technology resources. The platform in the cloud provides the infrastructure (eg computing power, storage space) that does not have to be installed and configured in contrast to the hardware you have purchased yourself. Cloud computing only pays for the resources that are used. For example, a web shop can increase its computing power in the Christmas business and book less in &quot;weak&quot; months.\r\nAccess is via the Internet or VPN. There are no ongoing investment costs after the initial setup, but resources such as Virtual servers, databases or storage services are charged only after they have been used.\r\n<span style=\"font-weight: bold;\">Where is my data on Amazon AWS?</span>\r\nThere are currently eight Amazon Data Centers (AWS Regions) in different regions of the world. For each Amazon AWS resource, only the customer can decide where to use or store it. German customers typically use the data center in Ireland, which is governed by European law.\r\n<span style=\"font-weight: bold;\">How safe is my data on Amazon AWS?</span>\r\nThe customer data is stored in a highly secure infrastructure. Safety measures include, but are not limited to:\r\n<ul><li>Protection against DDos attacks (Distributed Denial of Service)</li><li>Defense against brute-force attacks on AWS accounts</li><li>Secure access: The access options are made via SSL.</li><li> Firewall: Output and access to the AWS data can be controlled.</li><li>Encrypted Data Storage: Data can be encrypted with Advanced Encryption Standard (AES) 256.</li><li>Certifications: Regular security review by independent certifications that AWS has undergone.</li></ul>\r\nEach Amazon data center (AWS region) consists of at least one Availability Zone. Availability Zones are stand-alone sub-sites that have been designed to be isolated from faults in other Availability Zones (independent power and data supply). Certain AWS resources, such as Database Services (RDS) or Storage Services (S3) automatically replicate your data within the AWS region to the different Availability Zones.\r\nAmazon AWS has appropriate certifications such as ISO27001 and has implemented a comprehensive security concept for the operation of its data center.\r\n<span style=\"font-weight: bold;\">Do I have to worry about hardware on Amazon AWS?</span>\r\nNo, all Amazon AWS resources are virtualized. Only Amazon takes care of the replacement and upgrade of hardware.\r\nNormally, you will not get anything out of defective hardware because defective storage media are exchanged by Amazon and since your data is stored multiple times redundantly, there is usually no problem either.\r\nIncidentally, if your chosen resources do not provide enough performance, you can easily get more CPU power from resources by just a few mouse clicks. You do not have to install anything new, just reboot your virtual machine or virtual database instance.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Amazon_Web_Services.png","alias":"amazon-web-services"},"693":{"id":693,"title":"Linux Administration","description":" Linux is an operating system or a kernel created by Linus Torvalds with other contributors.

It is a sub-discipline of project management in which software projects are planned, implemented, monitored and controlled.\r\nA software development process is concerned primarily with the production aspect of software development, as opposed to the technical aspect, such as software tools. These processes exist primarily for supporting the management of software development, and are generally skewed toward addressing business concerns. Many software development processes can be run in a similar way to general project management processes. Examples are:<br /><span style=\"font-style: italic;\">Interpersonal communication and conflict management and resolution.</span> Active, frequent and honest communication is the most important factor in increasing the likelihood of project success and mitigating problematic projects. The development team should seek end-user involvement and encourage user input in the development process. Not having users involved can lead to misinterpretation of requirements, insensitivity to changing customer needs, and unrealistic expectations on the part of the client. Software developers, users, project managers, customers and project sponsors need to communicate regularly and frequently. The information gained from these discussions allows the project team to analyze the strengths, weaknesses, opportunities and threats (SWOT) and to act on that information to benefit from opportunities and to minimize threats. Even bad news may be good if it is communicated relatively early, because problems can be mitigated if they are not discovered too late. For example, casual conversation with users, team members, and other stakeholders may often surface potential problems sooner than formal meetings. All communications need to be intellectually honest and authentic, and regular, frequent, high quality criticism of development work is necessary, as long as it is provided in a calm, respectful, constructive, non-accusatory, non-angry fashion. Frequent casual communications between developers and end-users, and between project managers and clients, are necessary to keep the project relevant, useful and effective for the end-users, and within the bounds of what can be completed. Effective interpersonal communication and conflict management and resolution are the key to software project management. No methodology or process improvement strategy can overcome serious problems in communication or mismanagement of interpersonal conflict. Moreover, outcomes associated with such methodologies and process improvement strategies are enhanced with better communication. The communication must focus on whether the team understands the project charter and whether the team is making progress towards that goal. End-users, software developers and project managers must frequently ask the elementary, simple questions that help identify problems before they fester into near-disasters. While end-user participation, effective communication and teamwork are not sufficient, they are necessary to ensure a good outcome, and their absence will almost surely lead to a bad outcome.<br /><span style=\"font-style: italic;\">Risk management</span> is the process of measuring or assessing risk and then developing strategies to manage the risk. In general, the strategies employed include transferring the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk. Risk management in software project management begins with the business case for starting the project, which includes a cost-benefit analysis as well as a list of fallback options for project failure, called a contingency plan.<br /><span style=\"font-style: italic;\">Requirements management</span> is the process of identifying, eliciting, documenting, analyzing, tracing, prioritizing and agreeing on requirements and then controlling change and communicating to relevant stakeholders. New or altered computer system Requirements management, which includes Requirements analysis, is an important part of the software engineering process; whereby business analysts or software developers identify the needs or requirements of a client; having identified these requirements they are then in a position to design a solution.<br /><span style=\"font-style: italic;\">Change management</span> is the process of identifying, documenting, analyzing, prioritizing and agreeing on changes to scope (project management) and then controlling changes and communicating to relevant stakeholders. Change impact analysis of new or altered scope, which includes Requirements analysis at the change level, is an important part of the software engineering process; whereby business analysts or software developers identify the altered needs or requirements of a client; having identified these requirements they are then in a position to re-design or modify a solution. Theoretically, each change can impact the timeline and budget of a software project, and therefore by definition must include risk-benefit analysis before approval.<br /><span style=\"font-style: italic;\">Software configuration management</span> is the process of identifying, and documenting the scope itself, which is the software product underway, including all sub-products and changes and enabling communication of these to relevant stakeholders. In general, the processes employed include version control, naming convention (programming), and software archival agreements.<br /><span style=\"font-style: italic;\">Release management</span> is the process of identifying, documenting, prioritizing and agreeing on releases of software and then controlling the release schedule and communicating to relevant stakeholders. Most software projects have access to three software environments to which software can be released; Development, Test, and Production. In very large projects, where distributed teams need to integrate their work before releasing to users, there will often be more environments for testing, called unit testing, system testing, or integration testing, before release to User acceptance testing (UAT).\r\nAs a subdiscipline of project management, some regard the management of software development akin to the management of manufacturing, which can be performed by someone with management skills, but no programming skills.

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"},"731":{"id":731,"title":"IT Project Management","description":" IT project management is the process of planning, organizing and delineating responsibility for the completion of an organizations' specific information technology (IT) goals.\r\nIT project management includes overseeing projects for software development, hardware installations, network upgrades, cloud computing and virtualization rollouts, business analytics and data management projects and implementing IT services.\r\nIn addition to the normal problems that can cause a project to fail, factors that can negatively affect the success of an IT&nbsp; project include advances in technology during the project's execution, infrastructure changes that impact security and data management and unknown dependent relationships among hardware, software, network infrastructure and data.

In general, technical support provide help regarding specific problems with a product or service, rather than providing training, provision or customization of product, or other support services. Most companies offer technical support for the services or products they sell, either included in the cost or for an additional fee. Technical support may be delivered over by phone, e-mail, live support software on a website, or other tool where users can log an incident. Larger organizations frequently have internal technical support available to their staff for computer-related problems. The Internet can also be a good source for freely available tech support, where experienced users help users find solutions to their problems. In addition, some fee-based service companies charge for premium technical support services.\r\nTechnical support may be delivered by different technologies depending on the situation. For example, direct questions can be addressed using telephone calls, SMS, Online chat, Support Forums, E-mail or Fax; basic software problems can be addressed over the telephone or, increasingly, by using remote access repair services; while more complicated problems with hardware may need to be dealt with in person.\r\nTechnical support is a range of services providing assistance with technology such as televisions, computers, and software, typically aiming to help the user with a specific problem.","materialsDescription":"<span style=\"font-weight: bold; \">What are the categories of technical support?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Call in</span></span>\r\nThis type of technical support has been very common in the services industry.[citation needed] It is also known as &quot;Time and Materials&quot; (T&amp;M) IT support.[citation needed] The customer pays for the materials (hard drive, memory, computer, digital devices, etc.) and also pays the technician based on the pre-negotiated rate when a problem occurs.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Block hours</span></span>\r\nBlock hours allow the client to purchase a number of hours upfront at an agreed price. While it is commonly used to offer a reduced hourly rate, it can also simply be a standard non-reduced rate, or represent a minimum fee charged to a client before providing service. The premise behind this type of support is that the customer has purchased a fixed number of hours to use either per month or year. This allows them the flexibility to use the hours as they please without doing the paperwork and the hassle of paying multiple bills.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Managed services</span></span>\r\nManaged services means a company will receive a list of well-defined services on an ongoing basis, with well-defined &quot;response and resolution times&quot; for a fixed rate or a flat fee. This can include things like 24/7 monitoring of servers, 24/7 help desk support for daily computer issues, and on-site visits by a technician when issues cannot be resolved remotely.[citation needed] Some companies also offer additional services like project management, backup and disaster recovery, and vendor management in the monthly price. The companies that offer this type of tech support are known as managed services providers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Crowdsourced technical support</span></span>\r\nMany companies and organizations provide discussion boards for users of their products to interact; such forums allow companies to reduce their support costs without losing the benefit of customer feedback.\r\n<span style=\"font-weight: bold;\">What is outsourcing technical support?</span>\r\nWith the increasing use of technology in modern times, there is a growing requirement to provide technical support. Many organizations locate their technical support departments or call centers in countries or regions with lower costs. Dell was amongst the first companies to outsource their technical support and customer service departments to India in 2001. There has also been a growth in companies specializing in providing technical support to other organizations. These are often referred to as MSPs (Managed Service Providers).\r\nFor businesses needing to provide technical support, outsourcing allows them to maintain a high availability of service. Such need may result from peaks in call volumes during the day, periods of high activity due to introduction of new products or maintenance service packs, or the requirement to provide customers with a high level of service at a low cost to the business. For businesses needing technical support assets, outsourcing enables their core employees to focus more on their work in order to maintain productivity. It also enables them to utilize specialized personnel whose technical knowledge base and experience may exceed the scope of the business, thus providing a higher level of technical support to their employees.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Technical_Support.png","alias":"technical-support"},"735":{"id":735,"title":"Installation and configuration","description":" Installation or setup is the act of making the system or program ready for execution. Because the process varies for each program and each computer, programs (including operating systems) often come with an installer, a specialized program responsible for doing whatever is needed for their installation. The configuration is an arrangement of functional units according to their nature, number, and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware, settings, and documentation. The configuration affects system function and performance.\r\nSome computer programs can be executed by simply copying them into a folder stored on a computer and executing them. Other programs are supplied in a form unsuitable for immediate execution and therefore need an installation procedure. Once installed, the program can be executed again and again, without the need to reinstall before each execution.\r\nCommon operations performed during software installations include:\r\n<ul><li>Making sure that necessary system requirements are met</li><li>Checking for existing versions of the software</li><li>Creating or updating program files and folders</li><li>Adding configuration data such as configuration files, Windows registry entries or environment variables</li><li>Making the software accessible to the user, for instance by creating links, shortcuts or bookmarks</li><li>Configuring components that run automatically, such as daemons or Windows services</li><li>Performing product activation</li><li>Updating the software versions</li></ul>\r\nThese operations may require some charges or be free of charge.

For instance, a typical configuration for a PC consists of 32MB (megabytes) main memory, a floppy drive, a hard disk, a modem, a CD-ROM drive, a VGA monitor, and the Windows operating system.\r\nMany software products require that the computer have a certain minimum configuration. For example, the software might require a graphics display monitor and a video adapter, a particular microprocessor, and a minimum amount of main memory.\r\nWhen you install a new device or program, you sometimes need to configure it, which means to set various switches and jumpers (for hardware) and to define values of parameters (for software). For example, the device or program may need to know what type of video adapter you have and what type of printer is connected to the computer.

System testing seeks to detect defects both within the &quot;inter-assemblages&quot; and also within the system as a whole. The actual result is the behavior produced or observed when a component or system is tested.\r\nSystem testing is performed on the entire system in the context of either functional requirement specifications (FRS) or system requirement specification (SRS), or both. System testing tests not only the design but also the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds defined in the software or hardware requirements specification(s).\r\nSoftware 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. Software testing involves the execution of a software component or system component to evaluate one or more properties of interest. In general, these properties indicate the extent to which the component or system under test meets the requirements that guided its design and development, responds correctly to all kinds of inputs, performs its functions within an acceptable time, is sufficiently usable, can be installed and run in its intended environments, and achieves the general result its stakeholders desire. As the number of possible tests for even simple software components is practically infinite, all software testing uses some strategy to select tests that are feasible for the available time and resources.\r\nMobile-device testing assures the quality of mobile devices, like mobile phones, PDAs, etc. The testing will be conducted on both hardware and software. And from the view of different procedures, the testing comprises R&amp;D testing, factory testing and certification testing.

It may be regarded as a type of issue tracking system.\r\nMany bug tracking systems, such as those used by most open-source software projects, allow end-users to enter bug reports directly. Other systems are used only internally in a company or organization doing software development. Typically bug tracking systems are integrated with other project management software.\r\nA bug tracking system is usually a necessary component of a good software development infrastructure, and consistent use of a bug or issue tracking system is considered one of the &quot;hallmarks of a good software team&quot;.\r\nA major component of a bug tracking system is a database that records facts about known bugs. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.\r\nTypical bug tracking systems support the concept of the life cycle for a bug which is tracked through the status assigned to the bug. A bug tracking system should allow administrators to configure permissions based on status, move the bug to another status, or delete the bug. The system should also allow administrators to configure the bug statuses and to what extent a bug in a particular status can be moved. Some systems will e-mail interested parties, such as the submitter and assigned programmers, when new records are added or the status changes.\r\nThe main benefit of a bug-tracking system is to provide a clear centralized overview of development requests (including both bugs and improvements, the boundary is often fuzzy), and their state. The prioritized list of pending items (often called backlog) provides valuable input when defining the product road map, or maybe just &quot;the next release&quot;.\r\nIn a corporate environment, a bug-tracking system may be used to generate reports on the productivity of programmers at fixing bugs. However, this may sometimes yield inaccurate results because different bugs may have different levels of severity and complexity. The severity of a bug may not be directly related to the complexity of fixing the bug. There may be different opinions among the managers and architects.\r\nA local bug tracker (LBT) is usually a computer program used by a team of application support professionals (often a help desk) to keep track of issues communicated to software developers. Using an LBT allows support professionals to track bugs in their &quot;own language&quot; and not the &quot;language of the developers.&quot; In addition, an LBT allows a team of support professionals to track specific information about users who have called to complain — this information may not always be needed in the actual development queue. Thus, there are two tracking systems when an LBT is in place.","materialsDescription":" <span style=\"font-weight: bold;\">What does Bug Tracking mean?</span>\r\nBug tracking is a process used by quality assurance personnel and programmers to keep track of software problems and resolutions.

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","alias":"chatbot-development"},"844":{"id":844,"title":"Data access","description":"Data access is a generic term referring to a process which has both an IT-specific meaning and other connotations involving access rights in a broader legal and/or political sense. Two fundamental categories of data access exist:\r\n<ul><li>sequential access (as in magnetic tape, for example)</li><li>random access (as in indexed media)</li></ul>\r\nThe <span style=\"font-weight: bold;\">sequential method</span> requires information to be moved within the disk using a seek operation until the data is located. Each segment of data has to be read one after another until the requested data is found. Reading data <span style=\"font-weight: bold;\">randomly </span>allows users to store or retrieve data anywhere on the disk, and the data is accessed in constant time.\r\nOftentimes when using random access, the data is split into multiple parts or pieces and located anywhere randomly on a disk. Sequential files are usually faster to load and retrieve because they require fewer seek operations.\r\nAccess data management crucially involves authorization to access different data repositories. Data access solutions can help distinguish the abilities of administrators and users. For example, administrators may have the ability to remove, edit and add data, while general users may not even have &quot;read&quot; rights if they lack access to particular information.\r\nA <span style=\"font-weight: bold;\">data access right</span> (DAR) is a permission that has been granted that allows a person or computer program to locate and read digital information at rest. Digital access rights play and important role in information security and compliance.\r\nIn compliance, DARs are often granted to data subjects by law. For example, under the General Data Protection Regulation (GDPR) in the European Union, a data subject has the right to access their own personal data and request a correction or erasure.\r\nTo avoid losing or corrupting corporate data, organizations should grant only the necessary required access to each user, a concept known as the <span style=\"font-weight: bold;\">principle of least privilege</span> (POLP). To ensure confidentiality, information should be used by authorized personnel only. To maintain data integrity, data should not be modified accidentally or voluntarily. Additionally, to provide data availability, the system should operate within the required levels of service.\r\nHistorically, each repository (including each different database, file system, etc.), might require the use of different methods and languages, and many of these repositories stored their content in different and incompatible formats.\r\nOver the years standardized languages, methods, and formats, have developed to serve as interfaces between the often proprietary, and always idiosyncratic, specific languages and methods. Such standards include SQL (1974- ), ODBC (ca 1990- ), JDBC, XQJ, ADO.NET, XML, XQuery, XPath (1999- ), and Web Services.\r\nSome of these standards enable translation of data from unstructured (such as HTML or free-text files) to structured (such as XML or SQL). Structures such as connection strings and DBURLs can attempt to standardise methods of connecting to databases.<br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What is a database?</span></h1>\r\nA database is a collection of related data which represents some aspect of the real world. A database system is designed to be built and populated with data for a certain task.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What is DBMS?</span></h1>\r\nDatabase Management System (also known as DBMS) is a access database software for storing and retrieving users' data by considering appropriate security measures. It allows users to create their own databases as per their requirement.\r\nIt consists of a group of programs which manipulate the database and provide an interface between the database. It includes the user of the database and other application programs.\r\nThe DBMS accepts the request for data from an application and instructs the operating system to provide the specific data. In large systems, a DBMS helps users and other third-party software to store and retrieve data.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the best data access rights practices?</span></h1>\r\nTo keep data access control issues from arising, the following practices are recommended:\r\n<ul><li>Company security policies should specify what employees can and cannot do on their computers. For example, will individual user data access to allow personal emails, file downloads, software installation, information ownership and authorized or unauthorized website access.</li><li>Data should be classified based on its degree of confidentiality (and the risks associated with being leaked) and criticality (the integrity and the risk of alteration or destruction).</li><li>Control to data should be established using required authorization or authentication and by employing traceability (which consists of tracking access to sensitive IT resources).</li><li>Regular detailed audits should be performed to help set up controls surrounding identity management, privileged users and access to resources.</li><li>The rights of users should be limited. For example, Windows 10 offers standard and administrator accounts, but most users should just have standard accounts to complete their daily tasks.</li></ul>\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Data_access.png","alias":"data-access"}},"companyUrl":"https://yourserveradmin.com/","countryCodes":["DEU","USA"],"certifications":[],"isSeller":true,"isSupplier":true,"isVendor":false,"presenterCodeLng":"","seo":{"title":"YOURSERVERADMIN","keywords":"","description":"✔Cloud&amp;DevOps solutions&nbsp; ✔Web&amp;Mobile Development\r\n\r\n➤ ➤&nbsp; YOURSERVERADMIN team is a group of passionate and motivated professionals in DevOps, server management, and software development.","og:title":"YOURSERVERADMIN","og:description":"✔Cloud&amp;DevOps solutions&nbsp; ✔Web&amp;Mobile Development\r\n\r\n➤ ➤&nbsp; YOURSERVERADMIN team is a group of passionate and motivated professionals in DevOps, server management, and software development.","og:image":"https://old.roi4cio.com/uploads/roi/company/small_1.png"},"eventUrl":"","vendorPartners":[],"supplierPartners":[],"vendoredProducts":[],"suppliedProducts":[],"partnershipProgramme":null}},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
