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>. By delegating some of your business processes to a third party, you’ll give your in-house employees the opportunity to focus on more meaningful tasks.<br /><span style=\"font-weight: bold; \">To Accelerate Business Processes.</span> When you stop wasting time on mundane, time-consuming processes, you’ll be able to move forward with your core offering a lot faster.<br /><span style=\"font-weight: bold; \">To Share Risks.</span> When you delegate a part of non-focus functionality by outsourcing it to a third-party vendor, you give away the responsibility and related risks.","materialsDescription":"<h3 class=\"align-center\">What are the Types of IT Outsourcing?</h3>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Project-Based Model.</span> The client hires a team to implement the part of work that is already planned and defined. 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"},"567":{"id":567,"title":"Graphics Design","description":" Graphic design is the process of visual communication and problem-solving through the use of typography, photography, and illustration. The field is considered a subset of visual communication and communication design, but sometimes the term &quot;graphic design&quot; is used synonymously. Graphic designers create and combine symbols, images and text to form visual representations of ideas and messages. They use typography, visual arts, and page layout techniques to create visual compositions. Common uses of graphic design include corporate design (logos and branding), editorial design (magazines, newspapers and books), wayfinding or environmental design, advertising, web design, communication design, product packaging, and signage.\r\nGraphic design is applied to everything visual, from road signs to technical schematics, from interoffice memorandums to reference manuals.\r\nDesign can aid in selling a product or idea. It is applied to products and elements of company identity such as logos, colors, packaging and text as part of branding (see also advertising). Branding has become increasingly more important in the range of services offered by graphic designers. Graphic designers often form part of a branding team.\r\nGraphic design is applied in the entertainment industry in decoration, scenery and visual story telling. Other examples of design for entertainment purposes include novels, vinyl album covers, comic books, DVD covers, opening credits and closing credits in filmmaking, and programs and props on stage. This could also include artwork used for T-shirts and other items screenprinted for sale.\r\nFrom scientific journals to news reporting, the presentation of opinion and facts is often improved with graphics and thoughtful compositions of visual information - known as information design. Newspapers, magazines, blogs, television and film documentaries may use graphic design. With the advent of the web, information designers with experience in interactive tools are increasingly used to illustrate the background to news stories. Information design can include data visualization, which involves using programs to interpret and form data into a visually compelling presentation, and can be tied in with information graphics.","materialsDescription":"<span style=\"font-weight: bold;\">What is graphic design and what does it include?</span>\r\nGraphic design is a design process that combines text and graphics in a way that is intended to communicate a specific message.\r\n<span style=\"font-weight: bold;\">Where is graphic design used?</span>\r\nYou will find graphic design in company logos, printed materials like brochures, posters, signs, greeting cards, postcards, business cards, billboards and ads. Advances in technology have brought us the digital environment complete with websites, online ads, virtual brochures and presentations, and so very much more.\r\n<span style=\"font-weight: bold;\">What do graphic designers use to create these designs?</span>\r\nGraphic designers can use hand-illustrated designs as well as computer-aided designs thanks to a wide range of software with nearly endless digital design tools. The availability of software like Adobe Illustrator and Photoshop have become staples of the graphic designer.\r\n<span style=\"font-weight: bold;\">What can a graphic designer do that I can’t do?</span>\r\nA graphic designer does more than just put their creative skills to work. Though most graphic designers are intuitively creative already, they have generally spent time studying numerous design principles. It’s vital to understand how to use design elements to transmit the required messages and values as well as evoke a certain feeling in the viewer. As a visual communicator, they leverage these design elements and use concepts such as color, typography, space, balance, form and lines to create their visual message.\r\nSome graphic designers are also able to understand the more technical aspects of the design required to create digital assets for a company. For example, a web designer is often able to create wireframes, workflows, and sitemaps and understand how to develop easy navigation for the user experience.\r\n<span style=\"font-weight: bold;\">What else does a graphic designer accomplish as part of the work they produce for a client?</span>\r\nBesides turning their client’s vision, brand image and value proposition into a graphic display, a designer will undertake many specialty tasks as part of a graphic design project. The specialty tasks include collaborating on the concept (usually with a team), attending meetings about the project, paying attention to what customers are clicking on, doing presentations that explain the various potential designs, revising designs, and preparing asset files for others on the team and for client use.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Graphics_Design.png","alias":"graphics-design"},"569":{"id":569,"title":"Website Design","description":" Web design is the process of creating websites. It encompasses several different aspects, including webpage layout, content production, and graphic design. While the terms web design and web development are often used interchangeably, web design is technically a subset of the broader category of web development.\r\nWebsites are created using a markup language called HTML. Web designers build webpages using HTML tags that define the content and metadata of each page. The layout and appearance of the elements within a webpage are typically defined using CSS, or cascading style sheets. Therefore, most websites include a combination of HTML and CSS that defines how each page will appear in a browser.\r\nSome web designers prefer to hand code pages (typing HTML and CSS from scratch), while others use a &quot;WYSIWYG&quot; editor like Adobe Dreamweaver. This type of editor provides a visual interface for designing the webpage layout and the software automatically generates the corresponding HTML and CSS code. Another popular way to design websites is with a content management system like WordPress or Joomla. These services provide different website templates that can be used as a starting point for a new website. Webmasters can then add content and customize the layout using a web-based interface.\r\nWhile HTML and CSS are used to design the look and feel of a website, images must be created separately. Therefore, graphic design may overlap with web design, since graphic designers often create images for use on the Web. Some graphics programs like Adobe Photoshop even include a &quot;Save for Web…&quot; option that provides an easy way to export images in a format optimized for web publishing.","materialsDescription":" <span style=\"font-weight: bold;\">Why is Web Design Important?</span>\r\nIt can be difficult to understand why most businesses are willing to pay top dollar for web design work. After all, having a functional website matters more than how it looks, right? Unfortunately, this isn’t the case. Today, the most important aspect of an online business presence in web design.\r\nThis means that businesses should always try to find the best web styles that work for their businesses. Although there are several people who can create websites, it takes a skilled person to design a website that looks polished and functional. Here are some more reasons why web design is important to good business.\r\n<span style=\"font-weight: bold;\">A Good Site Increases Customer Conversion</span>\r\nWhen a business has a well-designed website, it becomes easier to get more customer conversions. This is because a well-designed website uses its elements to lead customers directly to what they need without distractions.\r\n<span style=\"font-weight: bold;\">A Responsive Website Helps Business Reach More Clients</span>\r\nAccording to recent research by Pew Research Center, it was discovered that more and more users are using their mobile phones to do business. This means that businesses need to take advantage of this new set of customers by creating websites that can get clients who are away from their computers.\r\n<span style=\"font-weight: bold;\">Websites Help in Business Branding</span>\r\nA poor looking website will damage the brand of any company while a scummy-looking website drives customers away.

The product is called a <span style=\"font-weight: bold; \">3D model.</span> Someone who works with 3D models may be referred to as a <span style=\"font-weight: bold; \">3D artist.</span> It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices.\r\n3D modeling can be achieved manually with specialized 3D model design software, such as <span style=\"font-weight: bold; \">computer-aided design</span> (CAD) programs, that lets an artist create and deform polygonal surfaces or by scanning real-world objects into a set of data points that can be used to represent the object digitally.\r\nSoftware to create 3D models is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called <span style=\"font-weight: bold; \">modeling applications</span> or <span style=\"font-weight: bold; \">modelers</span>.\r\nThree-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created by hand, algorithmically (procedural modeling), or scanned. Their surfaces may be further defined with texture mapping.\r\nAlthough complex mathematical formulas are at the foundation of 3D drawing software, the programs automate computation for users and have tool-based user interfaces. 3D models are an output of 3D modeling and are based on a variety of digital representations. Boundary representation (B-rep) uses mathematically defined surfaces such as cones, spheres and NURBS (non-uniform rational basis spline) which are connected by topology to accurately represent objects as water-tight volumes. B-rep models are the preferred solution for engineering, and many 3D modeling applications for the design, simulation and manufacture of consumer and industrial products are B-rep based. \r\nVirtual 3D models can be turned into physical objects through 3D printing or traditional manufacturing processes. Models can also be converted into a static image through 3D rendering, commonly used to create photo-realistic representation for sales, marketing and eCommerce applications. 3D models can be created by the process of reverse engineering, in which 3D scanning technology is used to create digital replicas of real-world objects, including manufactured parts and assemblies, free-form models designed in clay and human anatomy. Modern 3d modeling and animation tools create and interact with a “digital twin”, which is used to develop, test, simulate and manufacture its real world counterpart as part of the product lifecycle.\r\n3D modeling is used in a wide range of fields, including engineering, architecture, entertainment, film, special effects, game development, and commercial advertising. It is an integral part of many creative careers. Engineers and architects use it to plan and design their work. Animators and game designers rely on 3D modeling tools to bring their ideas to life. And just about every Hollywood blockbuster uses 3D modeling for special effects, to cut costs, and to speed up production.\r\n\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Criteria to consider when choosing between 3D software programs</h1>\r\nThere is a wide range of 3D modeling and animation software addressing <span style=\"font-weight: bold; \">different fields of activity</span>.

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).

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.

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.

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.

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.

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. The future is all connected, and .NET will get us there.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Net_Development.png","alias":"net-development"},"611":{"id":611,"title":"ObjectiveC Development","description":"Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for the macOS, iOS and iPadOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch until the introduction of Swift in 2014.\r\nThe language was originally developed in the early 1980s. It was later selected as the main language used by NeXT for its NeXTSTEP operating system, from which macOS and iOS are derived. Portable Objective-C programs that do not use Apple libraries, or those using parts that may be ported or reimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang.\r\nObjective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension.\r\nObjective-C was invented in the early 1980s as a means to add Object-Oriented programming capabilities to C. The inventors, Brad Cox and Tom Love, thought that Smalltalk (an early OO language) could provide the tools needed for truly re-usable code and for creating development environments for systems developers.\r\nCox began by writing a pre-processor for C that allowed for the inclusion of Smalltalk-like code, which would then be rendered into compilable C. This turned into a fully-Object-Oriented C extension.\r\nObjective-C was eventually fully defined and described in the book Object-Oriented Programming: An Evolutionary Approach.\r\nNeXT licensed Objective-C in 1988 and developed several tools based on it. These tools eventually became (after several intermediate steps) the Cocoa development environment, which is used by several Apple systems: Mac OS X, iOS, Apple WatchOS.\r\nFor several years now, apps are written for one of these Apple operating systems needed to be written (or compiled to, or run on top of) Objective-C.

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's used to make many of the websites and applications you use every day. Drupal has great standard features, like easy content authoring, reliable performance, and excellent security. But what sets it apart is its flexibility; modularity is one of its core principles. Its tools help you build the versatile, structured content that dynamic web experiences need.\r\nIt's also a great choice for creating integrated digital frameworks. You can extend it with anyone, or many, of thousands of add-ons. Modules expand Drupal's functionality. Themes let you customize your content's presentation. Distributions are packaged Drupal bundles you can use as starter-kits. Mix and match these components to enhance Drupal's core abilities. Or, integrate Drupal with external services and other applications in your infrastructure. No other content management software is this powerful and scalable.\r\nThe Drupal project is open source software. Anyone can download, use, work on, and share it with others. It's built on principles like collaboration, globalism, and innovation. It's distributed under the terms of the GNU General Public License (GPL). There are no licensing fees, ever. Drupal will always be free.","materialsDescription":" <span style=\"font-weight: bold;\">What can Drupal do? 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.

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.

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

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 incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Finally, Python is portable: it runs on many Unix variants, on the Mac, and on Windows 2000 and later.\r\n<span style=\"font-weight: bold;\">What is the Python Software Foundation?</span>\r\nThe Python Software Foundation is an independent non-profit organization that holds the copyright on Python versions 2.1 and newer.

The examples of eCommerce business include supply chain, funds transfer, banking and electronic data interchange (EDI) and others. The electronic transactions are carried out through many eCommerce software platforms and eCommerce applications that are integrated with online websites with the help of eCommerce developers. The eCommerce applications are linked with the payment gateways for a smooth transfer of credit from one entity to another one.\r\nAn eCommerce developer is a very important role in eCommerce app development and web services to realize the power of online sales and marketing in all domains of businesses. The eCommerce developers are normally the web developers with additional exposure to the eCommerce tools and platforms commonly used in online businesses. HTML, CSS, JavaScript, Python, PHP, Ruby on Rail and related technologies are the fundamental components of eCommerce developer skills. In addition to those skills, the knowledge of eCommerce software platforms and API integration is very important for a good eCommerce developer resume.\r\nA good eCommerce website should be highly professional looking with great features and intuitive interface for the checkout process. This is only possible with the help of professional eCommerce developers. You need to evaluate a lot of things before you decide to hire eCommerce developers such as the backend technologies of your website, type of eCommerce, a domain of business, type of database and many others.

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

It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.\r\nWeb browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.\r\nHTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as &lt;img /&gt; and &lt;input /&gt; directly introduce content into the page. Other tags such as &lt;p&gt; surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.\r\nHTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.","materialsDescription":" <span style=\"font-weight: bold;\">What is HTML5?</span>\r\nHTML5 contains powerful capabilities for Web-based applications with more powerful interaction, video support, graphics, more styling effects, and a full set of APIs. HTML5 adapts to any device, whether desktop, mobile, tablet, or television. HTML5 is an open platform developed under royalty-free licensing terms.\r\nPeople use the term HTML5 in two ways:\r\n<ul><li>to refer to a set of technologies that together form the future Open Web Platform. These technologies include HTML5 specification, CSS3, SVG, MathML, Geolocation, XmlHttpRequest, Context 2D, Web Fonts (WOFF) and others. The boundary of this set of technologies is informal and changes over time;</li><li>to refer to the HTML5 specification, which is, of course, also part of the Open Web Platform.</li></ul>\r\nAlthough it would be great if people used one term to refer to the specification and another term to refer to a set of specifications, in practice people use the term both ways.\r\n<span style=\"font-weight: bold;\">HTML5 has been cited by many thought leaders as the future of the Web. Why is HTML5 generating this excitement?</span>\r\nThere is huge demand for open standards that allow the creation of rich internet applications. Watching videos, finding the nearest restaurant, accessing emails while being offline are just some of the powerful new capabilities enabled by the set of specifications in development at W3C.\r\nOne aspect that interests W3C, in particular, is enabling people to combine different technologies. W3C works to ensure not just interoperable support in the software of a single specification, but compatibility among specifications.\r\nEven though HTML5 is still a draft, browser vendors are deploying features and generating a lot of excitement in the IT industry. This experience, in turn, allows W3C to revise its drafts. In this way, the final standard can transparently inform implementers where they need to pay close attention to security and privacy issues.\r\n<span style=\"font-weight: bold;\">When can I use HTML5?</span>\r\nPeople can already use parts of the platform that interoperate, but W3C's mission is global interoperable, to ensure that the web is available to all. Not all elements are fully implemented yet and some of them provide builtin fallback mechanisms, such as &lt;video&gt; or &lt;input&gt;. One can use HTML5 today, knowing the existing limitations and ensuring proper fallbacks.\r\n<span style=\"font-weight: bold;\">Which Web Browsers support HTML5?</span>\r\nW3C encourages implementation and testing long before a specification becomes a standard to ensure that two people can read a specification independently and write interoperable software. Early adopters provide implementers and W3C with tremendously valuable feedback because they help identify where interoperability issues exist.\r\n<span style=\"font-weight: bold;\">Do you think that the benefits of HTML5, such as its neutrality, rich graphics, no need plug-ins, outweigh the security risk it carries?</span>\r\nNow entering its third decade, the Web has evolved from a Web of documents into a formidable platform for networked applications that let us share information and services over the Internet. In this highly connected environment, it is important that powerful Web applications be designed with sensitivity to user privacy and security needs. The risks associated with modern Web applications are familiar to the HTML5 community.\r\nHTML5 and related specifications are being developed in W3C's open standards process. This process allows an expert review of features along with their security and privacy implications. Rich functionality that was previously available only through proprietary plugins is now documented in an open specification for all experts to review and improve. We're pleased to see the HTML5 specifications subject to rigorous public review since that helps make the Web a more secure environment.\r\nSome security issues are not confined to HTML5. W3C and IETF are working closely to specify technologies and protocol extensions to mitigate some issues (such as cross-site request forgery and cross-site scripting).\r\n<span style=\"font-weight: bold;\">Will there be an HTML6?</span>\r\nNo work is currently happening on HTML6 but feature requests that are not planned to be addressed in HTML5 are available at listed under HTML.next.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_HTML_Development.png","alias":"html-development"},"641":{"id":641,"title":"XML Development","description":"","materialsDescription":"","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_XML_Development.png","alias":"xml-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. JavaScript was influenced by programming languages such as Self and Scheme.

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

The syntax of the programming language is similar to COBOL, but it is very different from languages such as Java, C, or Python. Since ABAP is a non-standardized programming language, it is only used in connection with SAP programs. However, ABAP has powerful concepts for developing business applications in this environment. Since 1990, ABAP has also been a so-called object-oriented programming language.\r\nAs an SAP developer, you work closely with other software engineers. Together, you will develop, implement and maintain the modules and features of the software that works for your customer or employer. Specifically, these can be architectures, applications, and specific solutions.\r\nABAP is one of the many application-specific fourth-generation languages (4GLs) first developed in the 1980s. It was originally the report language for SAP R/2, a platform that enabled large corporations to build mainframe business applications for materials management and financial and management accounting. ABAP establish integration between independent software.\r\nABAP used to be an abbreviation of Allgemeiner Berichts-Aufbereitungs-Prozessor, German for &quot;generic report preparation processor&quot;, but was later renamed to the English Advanced Business Application Programming. ABAP was one of the first languages to include the concept of Logical Databases (LDBs), which provides a high level of abstraction from the basic database level(s),which supports every platform, language and units.\r\nThe ABAP language was originally used by developers to develop the SAP R/3 platform. It was also intended to be used by SAP customers to enhance SAP applications – customers can develop custom reports and interfaces with ABAP programming. The language was geared towards more technical customers with programming experience.\r\nABAP remains as the language for creating programs for the client-server R/3 system, which SAP first released in 1992. As computer hardware evolved through the 1990s, more and more of SAP's applications and systems were written in ABAP. By 2001, all but the most basic functions were written in ABAP. In 1999, SAP released an object-oriented extension to ABAP called ABAP Objects, along with R/3 release 4.6.\r\nSAP's current development platform NetWeaver supports both ABAP and Java.\r\nABAP has an abstraction between the business applications, the operating system and database. This ensures that applications do not depend directly upon a specific server or database platform and can easily be ported from one platform to another.\r\nSAP Netweaver currently runs on UNIX (AIX, HP-UX, Solaris, Linux), Microsoft Windows, i5/OS on IBM System i (formerly iSeries, AS/400), and z/OS on IBM System z (formerly zSeries, S/390). Supported databases are HANA, SAP ASE (formerly Sybase), IBM DB2, Informix, MaxDB, Oracle, and Microsoft SQL Server (support for Informix was discontinued in SAP Basis release 7.00).","materialsDescription":" <span style=\"font-weight: bold;\">What is a SAP Developer?</span>\r\nSAP is the #1 creator of business software solutions. It's the fourth largest software company globally -- just a couple notches behind Microsoft. What this means is that there's a huge market for developers who are knowledgeable of SAP solutions -- outside of the parent company and outside of Germany. Among these solutions are SAP Business Warehouse, SAP Business Objects, and Sybase mobile.\r\nSAP has contributed to one thing that most software companies haven’t – its own computer language. One possible role for a SAP developer is to write programs using Advanced Business Application Programming (ABAP). Some SAP projects are also developed in Java.\r\nMany U.S. companies use SAP technologies. By perusing job posting, you may find some big names: Costco, REI, Nike, even Raytheon.\r\nThere are a lot of different roles from SAP systems analyst to SAP architect. It can be surprising just how much know-how and education these positions require.\r\n<span style=\"font-weight: bold;\">Education</span>\r\nThe bachelor’s degree is the typical entry point for a career in software development. Industry-specific knowledge can be important – in the case of a SAP developer, it is often finance or business.\r\nMany nationally advertised SAP positions favor candidates with master’s degrees; depending on the position, the master’s maybe in business administration or a more technical field.\r\nHigher-level software development positions typically ask for experience taking a software product through the lifecycle. They may ask for knowledge of specific models -- e.g. the Full Lifecycle Model.\r\nThose with SAP expertise often go on to work as consultants. There are two types: functional consultant and technical consultant. The functional consultant is focused on meeting business needs and the technical consultant, well you can guess what their focus is.\r\n<span style=\"font-weight: bold;\">SAP Certification</span>\r\nLike its &quot;big brothers&quot; Microsoft and Oracle, SAP offers a host of certifications. They are available in technology, development, and application.\r\nIt is possible to simultaneously earn a master's degree and SAP certification. The masters may be in any of several fields, including business engineering and computer science.\r\nJob advancement takes more than just technical skills. A 2012 survey of SAP professionals asked what skills were most important for advancement and raises. Project management topped the list. Business skills and communication skills were also seen as important.\r\nDevelopers can find lots of resources on the site of the SAP Community Network.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SAP_Applications_Development.png","alias":"sap-applications-development"},"661":{"id":661,"title":"Sharepoint Development","description":" SharePoint is a web-based collaborative platform that integrates with Microsoft Office. Launched in 2001, SharePoint is primarily sold as a document management and storage system, but the product is highly configurable and usage varies substantially among organizations.\r\nSharePoint infuses AI into the mobile app experience to keep you focused and productive while on the go. AI builds an understanding of what you work on, how you work, and how your colleagues' work relates to you. When you need expertise, content, or resources when you're on the go, SharePoint is a great place to start looking.\r\nSharePoint is comprised of a multipurpose set of technologies that has tight integration with Office 365 as well as handy document management capabilities.\r\nAccording to Microsoft, SharePoint is used by 78% of Fortune 500 companies. Between 2006 and 2011, Microsoft sold over 36.5 million user licenses.\r\nSharePoint is a collection of software products and components that includes:\r\n<ul><li>a set of web applications for organizing collaboration;</li><li>functionality for creating web portals;</li><li>module for searching information in documents and information systems;</li><li>workflow management functionality and enterprise-wide content management system;</li><li>module for creating forms for entering information;</li><li>functionality for business analysis.</li></ul>\r\nMicrosoft states that SharePoint has 190 million users across 200,000 customer organizations.","materialsDescription":" <span style=\"font-weight: bold;\">Why is Microsoft SharePoint important?</span>\r\nSharePoint’s core functions are\r\n<ul><li>a) to store documents in a more effective format than a regular folder system, and</li><li>b) bring an organization together so that everyone receives critical information that’s relevant to them.</li></ul>\r\nHere are some benefits your organization can get from using SharePoint:\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Context around documents and folders</span></span>\r\nA traditional document storage facility is usually a folder on a server somewhere. The reason why SharePoint is more effective than the traditional method is that it brings context around the folder itself by tracking versions of the document. For example, in a traditional folder setup, you can’t have a running version history for each document or see any changes to the file name. Whereas with SharePoint, there’s more information provided about the file. It’s not just some file sitting in a folder; it’s an evolving piece of information that has a history as well as context.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Enable constant communication with all staff</span></span>\r\nIn the past, you might send a group email and copy everyone. The problem with that approach is a lot of information gets ignored or even lost, so some people might not get the information they need. For example, maybe you lost a company document and you missed an important discussion. Or maybe you did read it but afterward, it was very difficult to find and reference that information. SharePoint brings collaboration to the table so that all staff can see the important information and communication accordingly.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Store all information in a central location</span></span>\r\nThis can range from things such as updates from the CEO to important meetings or events. SharePoint brings all the information to one internal place so staff can quickly find the information they need. Other use cases might be general warnings about particular customers or even incidents that everyone needs to be aware of. With SharePoint, simply post the message and everyone can access it from there. Forget email or announcement boards; simply post it on SharePoint.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Encourage collaboration</span></span>\r\nSharePoint is really designed around getting the organization into a central point where they can collaborate. This is particularly important for organizations that are not geographically connected. With some branches working in a very isolated format, SharePoint provides staff with the ability to connect with each other via a portal. Where in the past some staff might only interact with the company during a company meeting, SharePoint brings those people together so everyone can work together, all the time. Collaboration fosters innovation and builds a company culture that spawns creative ideas.\r\n<span style=\"font-weight: bold;\">What are the challenges of Microsoft SharePoint?</span>\r\n<span style=\"font-weight: bold;\">Support for certain industry standards.</span> SharePoint's records-management capabilities give it the ability to save documents for legal or historical reasons. This can be a challenge in some industries (medical and financial) where there are complex regulatory requirements for record-keeping. In those cases, you should consult a professional about an industry-specific solution.\r\n<span style=\"font-weight: bold;\">Customize out of the box with third-party solutions.</span> Some organizations won’t find what they need out of the box. A third-party solution can help you build something you want. This can be easily achieved if you work with an IT service provider that has SharePoint experience.

PostgreSQL is developed by the PostgreSQL Global Development Group, a diverse group of many companies and individual contributors.\r\nPostgreSQL's developers pronounce PostgreSQL as /ˈpoʊstɡrɛs ˌkjuː ˈɛl/. It is abbreviated as Postgres because of ubiquitous support for the SQL standard among relational databases. Originally named POSTGRES, the name (Post Ingres) refers to the project's origins in that RDBMS that originated at University of California, Berkeley. After a review the PostgreSQL Core Team announced in 2007 that the product would continue to use the name PostgreSQL.\r\nPostgreSQL manages concurrency through multiversion concurrency control (MVCC), which gives each transaction a &quot;snapshot&quot; of the database, allowing changes to be made without affecting other transactions. This largely eliminates the need for read locks, and ensures the database maintains ACID principles. PostgreSQL offers three levels of transaction isolation: Read Committed, Repeatable Read and Serializable. Because PostgreSQL is immune to dirty reads, requesting a Read Uncommitted transaction isolation level provides read committed instead. PostgreSQL supports full serializability via the serializable snapshot isolation (SSI) method.\r\nPostgreSQL is available for the following operating systems: Linux (all recent distributions), 64-bit installers available for macOS (OS X) version 10.6 and newer – Windows (with installers available for 64-bit version; tested on latest versions and back to Windows 2012 R2, while for PostgreSQL version 10 and older a 32-bit installer is available and tested down to 32-bit Windows 2008 R1; compilable by e.g. Visual Studio, version 2013 up up to most recent 2019 version) – FreeBSD, OpenBSD, NetBSD, AIX, HP-UX, Solaris, and UnixWare; and not officially tested: DragonFly BSD, BSD/OS, IRIX, OpenIndiana, OpenSolaris, OpenServer, and Tru64 UNIX. Most other Unix-like systems could also work; most modern do support.\r\nPostgreSQL works on any of the following instruction set architectures: x86 and x86-64 on Windows and other operating systems; these are supported on other than Windows: IA-64 Itanium (external support for HP-UX), PowerPC, PowerPC 64, S/390, S/390x, SPARC, SPARC 64, ARMv8-A (64-bit) and older ARM (32-bit, including older such as ARMv6 in Raspberry Pi), MIPS, MIPSel, and PA-RISC. It was also known to work, but not tested in a while, on Alpha (dropped in 9.5), M68k, M32R, NS32k, and VAX. Beyond these, it is possible to build PostgreSQL for an unsupported CPU by disabling spinlocks.","materialsDescription":" <span style=\"font-weight: bold;\">What is PostgreSQL? How is it pronounced? What is Postgres?</span>\r\nPostgreSQL is pronounced Post-Gres-Q-L.\r\nPostgreSQL is an object-relational database system that has the features of traditional proprietary database systems with enhancements to be found in next-generation DBMS systems. PostgreSQL is free and the complete source code is available.\r\nPostgreSQL development is performed by a team of mostly volunteer developers spread throughout the world and communicating via the Internet. It is a community project and is not controlled by any company.\r\nPostgres is a widely-used nickname for PostgreSQL. It was the original name of the project at Berkeley and is strongly preferred over other nicknames. If you find 'PostgreSQL' hard to pronounce, call it 'Postgres' instead.\r\n<span style=\"font-weight: bold;\">Who controls PostgreSQL?</span>\r\nIf you are looking for a PostgreSQL gatekeeper, central committee, or controlling company, give up --- there isn't one. We do have a core committee and git committers, but these groups are more for administrative purposes than control. The project is directed by the community of developers and users, which anyone can join. All you need to do is subscribe to the mailing lists and participate in the discussions.\r\n<span style=\"font-weight: bold;\">Who is the PostgreSQL Global Development Group?</span>\r\nThe &quot;PGDG&quot; is an international, unincorporated association of individuals and companies who have contributed to the PostgreSQL project. The PostgreSQL Core Team generally act as spokespeople for the PGDG.\r\n<span style=\"font-weight: bold;\">Who is the PostgreSQL Core Team?</span>\r\nA committee of five to seven (currently six) senior contributors to PostgreSQL who do the following for the project: (a) set release dates, (b) handle confidential matters for the project, (c) act as spokespeople for the PGDG when required, and (d) arbitrate community decisions which are not settled by consensus. The current Core Team is listed on top of the contributor's page.\r\n<span style=\"font-weight: bold;\">What about the various PostgreSQL foundations?</span>\r\nWhile the PostgreSQL project utilizes non-profit corporations in the USA, Europe, Brazil, and Japan for fundraising and project coordination, these entities do not own the PostgreSQL code.\r\n<span style=\"font-weight: bold;\">What is the license of PostgreSQL?</span>\r\nPostgreSQL is distributed under a license similar to BSD and MIT. Basically, it allows users to do anything they want with the code, including reselling binaries without the source code. The only restriction is that you not hold us legally liable for problems with the software. There is also the requirement that this copyright appears in all copies of the software.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_PostgesSQL_Development.png","alias":"postgresql-development"},"679":{"id":679,"title":"Games Development","description":" Video game development is the process of creating a video game. The effort is undertaken by a developer, ranging from a single person to an international team dispersed across the globe. Development of traditional commercial PC and console games is normally funded by a publisher, and can take several years to reach completion. Indie games usually take less time and money and can be produced by individuals and smaller developers. The independent game industry has been on the rise, facilitated by the growth of accessible game development software such as Unity platform and Unreal Engine and new online distribution systems such as Steam and Uplay, as well as the mobile game market for Android and iOS devices.\r\nThe first video games, developed in the 1960s, were noncommercial. They required mainframe computers to run and were not available to the general public. Commercial game development began in the '70s with the advent of first-generation video game consoles and early home computers like the Apple I. At that time, owing to low costs and low capabilities of computers, a lone programmer could develop a full and complete game. However, in the late '80s and '90s, ever-increasing computer processing power and heightened expectations from gamers made it difficult for a single person to produce a mainstream console or PC game. The average cost of producing a triple-A video game slowly rose, from US$1–4 million in 2000, to over $5 million in 2006, then to over $20 million by 2010.\r\nMainstream commercial PC and console games are generally developed in phases: first, in pre-production, pitches, prototypes, and game design documents are written; if the idea is approved and the developer receives funding, then full-scale development begins. The development of a complete game usually involves a team of 20–100 individuals with various responsibilities, including designers, artists, programmers, and testers.\r\nThe game revenue from retails is divided among the parties along the distribution chain, such as — developer, publisher, retail, manufacturer and console royalty. Many developers fail to profit from this and go bankrupt. Many developers seek alternative economic models through Internet marketing and distribution channels to improve returns., as through a mobile distribution channel the share of a developer can be up to 70% of the total revenue and through an online distribution channel almost 100%.","materialsDescription":" <span style=\"font-weight: bold;\">How important are games?</span>\r\nThe popularity of smart gadgets like smartphones, tablets etc have opened up a new avenue of entertainment in the software industry and that is the domain of the mobile gaming sector.

Each structure comprises software elements, relations among them, and properties of both elements and relations. The architecture of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, laying out the tasks necessary to be executed by the design teams.\r\nSoftware architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. For example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Additionally, to satisfy the need for reliability the choice could be made to have multiple redundant and independently produced copies of the program, and to run these copies on independent hardware while cross-checking results.\r\nDocumenting software architecture facilitates communication between stakeholders, captures early decisions about the high-level design, and allows the reuse of design components between projects.","materialsDescription":" <span style=\"font-weight: bold; \">What is the scope of software architecture?</span>\r\nOpinions vary as to the scope of software architectures:\r\n<ul><li>Macroscopic system structure: this refers to architecture as a higher-level abstraction of a software system that consists of a collection of computational components together with connectors that describe the interaction between these components.</li><li>The important stuff—whatever that is: this refers to the fact that software architects should concern themselves with those decisions that have a high impact on the system and its stakeholders.</li><li>That is fundamental to understanding a system in its environment.</li><li>Things that people perceive as hard to change: since designing the architecture takes place at the beginning of a software system's lifecycle, the architect should focus on decisions that &quot;have to&quot; be right the first time. Following this line of thought, architectural design issues may become non-architectural once their irreversibility can be overcome.</li><li>A set of architectural design decisions: software architecture should not be considered merely a set of models or structures, but should include the decisions that lead to these particular structures, and the rationale behind them. This insight has led to substantial research into software architecture knowledge management.</li></ul>\r\n<span style=\"font-weight: bold; \">What are the characteristics of software architecture?</span>\r\nSoftware architecture exhibits the following:\r\n<span style=\"font-weight: bold; \">A multitude of stakeholders:</span> software systems have to cater to a variety of stakeholders such as business managers, owners, users, and operators. These stakeholders all have their own concerns with respect to the system. Balancing these concerns and demonstrating that they are addressed is part of designing the system. This implies that architecture involves dealing with a broad variety of concerns and stakeholders, and has a multidisciplinary nature.\r\n<span style=\"font-weight: bold; \">Separation of concerns:</span> the established way for architects to reduce complexity is to separate the concerns that drive the design. Architecture documentation shows that all stakeholder concerns are addressed by modeling and describing the architecture from separate points of view associated with the various stakeholder concerns. These separate descriptions are called architectural views.\r\n<span style=\"font-weight: bold; \">Quality-driven:</span> classic software design approaches (e.g. Jackson Structured Programming) were driven by required functionality and the flow of data through the system, but the current insight is that the architecture of a software system is more closely related to its quality attributes such as fault-tolerance, backward compatibility, extensibility, reliability, maintainability, availability, security, usability, and other such –ilities. Stakeholder concerns often translate into requirements on these quality attributes, which are variously called non-functional requirements, extra-functional requirements, behavioral requirements, or quality attribute requirements.\r\n<span style=\"font-weight: bold; \">Recurring styles:</span> like building architecture, the software architecture discipline has developed standard ways to address recurring concerns. These &quot;standard ways&quot; are called by various names at various levels of abstraction. Common terms for recurring solutions are architectural style, tactic, reference architecture and architectural pattern.\r\n<span style=\"font-weight: bold; \">Conceptual integrity:</span> a term introduced by Fred Brooks in The Mythical Man-Month to denote the idea that the architecture of a software system represents an overall vision of what it should do and how it should do it. This vision should be separated from its implementation. The architect assumes the role of &quot;keeper of the vision&quot;, making sure that additions to the system are in line with the architecture, hence preserving conceptual integrity.\r\n<span style=\"font-weight: bold; \">Cognitive constraints:</span> an observation first made in a 1967 paper by computer programmer Melvin Conway that organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations. As with conceptual integrity, it was Fred Brooks who introduced it to a wider audience when he cited the paper and the idea in his elegant classic The Mythical Man-Month, calling it &quot;Conway's Law.&quot;\r\n<span style=\"font-weight: bold;\">What is the motivation of software architecture?</span>\r\nSoftware architecture is an &quot;intellectually graspable&quot; abstraction of a complex system. This abstraction provides a number of benefits:\r\n<ul><li><span style=\"font-style: italic;\">It gives a basis for an analysis of software systems' behavior before the system has been built.</span> The ability to verify that a future software system fulfills its stakeholders' needs without actually having to build it represents substantial cost-saving and risk-mitigation. A number of techniques have been developed to perform such analyses, such as ATAM.</li><li><span style=\"font-style: italic;\">It provides a basis for the re-use of elements and decisions.</span> A complete software architecture or parts of it, like individual architectural strategies and decisions, can be re-used across multiple systems whose stakeholders require similar quality attributes or functionality, saving design costs and mitigating the risk of design mistakes.</li><li><span style=\"font-style: italic;\">It supports early design decisions that impact a system's development, deployment, and maintenance life.</span> Getting the early, high-impact decisions right is important to prevent schedule and budget overruns.</li><li><span style=\"font-style: italic;\">It facilitates communication with stakeholders, contributing to a system that better fulfills their needs.</span> Communicating about complex systems from the point of view of stakeholders helps them understand the consequences of their stated requirements and the design decisions based on them.

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"},"687":{"id":687,"title":"Network Administration","description":" Computer networks are critical parts of almost every organization. Network and computer systems administrators are responsible for the day-to-day operation of these networks. They organize, install, and support an organization’s computer systems, including local area networks (LANs), wide area networks (WANs), network segments, intranets, and other data communication systems. Administrators manage an organization’s servers and desktop and mobile equipment. They ensure that email and data storage networks work properly. They also make sure that employees’ workstations are working efficiently and stay connected to the central computer network. In some cases, administrators help network architects design and analyze network models. They also participate in decisions about buying future hardware or software to upgrade their organization’s network. Some administrators provide technical support to computer users, and they also may supervise computer support specialists who help solve users’ problems.\r\nAs with many technical roles, network administrator positions require a breadth of technical knowledge and the ability to learn the intricacies of new networking and server software packages quickly. Within smaller organizations, the more senior role of a network engineer is sometimes attached to the responsibilities of the network administrator. It is common for smaller organizations to outsource this function.\r\nA computer network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices exchange data with each other along with network links (data connections). The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.\r\nNetwork computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, mobile phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.\r\nComputer networks differ in the transmission media used to carry their signals, the communications protocols to organize network traffic, the network's size, topology, and organizational intent. In most cases, communications protocols are layered on (i.e. work using) other more specific or more general communications protocols, except for the physical layer that directly deals with the transmission media.\r\nComputer networks support an enormous number of applications such as access to the World Wide Web, video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others.","materialsDescription":" <span style=\"font-weight: bold; \">What is a network administrator?</span>\r\nA network administrator is responsible for keeping an organization’s computer network up-to-date and operating as intended. Any company or organization that uses multiple computers or software platforms need a network admin to coordinate and connect the different systems. It seems simple enough—but there’s another common IT job title that may trip you up: systems administrator.\r\n<span style=\"font-weight: bold; \">Is a network administrator the same thing as a systems administrator?</span>\r\nIn short — not really. But the lines can blur depending on the work environment. Careers in IT can sometimes take a page from the rules of Whose Line Is It, Anyway? — “Where the titles don’t matter and the duties are made up!” While that’s clearly a bit of an exaggeration, in many smaller organizations, the terms “network administrator” and “systems administrator” are often interchangeable as they cover the same tasks. That being said, the differences between network and systems administrators become much clearer in large organizations. The best way to differentiate between the two is to examine the type of work they do.\r\n<span style=\"font-weight: bold; \">What are the job duties of network and systems administrators?</span>\r\nThe duties of a network administrator will vary considerably depending on the organization they work for. Some work as broad, jack-of-all-trades generalists who cover everything from hardware setup to troubleshooting servers while others have a much narrower focus.\r\nHere are some sample network and systems administrator job duties. In environments where the duties of network administrators and systems administrators are split and more clearly defined, the italicized duties align more with systems administrators:\r\n<ul><li>Configuring network hardware like servers, routers, and switches</li><li>Upgrading and repairing computer networks</li><li>Troubleshooting network issues</li><li>Assisting network architects with the design of network models</li><li>Deploying and updating software</li><li>Managing servers and their operating systems</li><li>Implementing security measures and basic testing</li><li>Managing cloud and physical network storage</li></ul>\r\n<span style=\"font-weight: bold;\">What skills or traits do the best network administrators possess?</span>\r\nObviously, network administration positions will require substantial technical competence, but there’s more to the job than just knowing your stuff. Here are a few of the most common nontechnical abilities that will benefit you as a network administrator:\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Analyzing and critical thinking</span></span>\r\nNetwork admins need to explore and solve problems logically and consistently. “[The] ability to take the concepts you’ve learned in school and understand how they work and affect other concepts is the bread and butter of being a network administrator,” says Brad Meyer, systems administrator at TechnologyAdvice. Even if you don’t yet know the solution, he believes thinking critically will help you get there.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Time management</span></span>\r\nNetwork admins juggle several projects, people and problems simultaneously. This means it’s essential to be organized in the present and looking ahead to prepare for what’s coming next. It’s like spinning plates—with a little practice, a network admin can keep everything balanced.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Interpersonal skills</span></span>\r\nNetwork admins work with a range of people, from network engineers to help desk employees to end-users, explains IT consultant Eric Jeffery. He says bridging the gap between diverse groups of people requires patience and understanding.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">A drive to learn more</span></span>\r\nThe IT field is no stranger to change—and new technologies can put even well-established network admins behind the eight balls. This means the best network admins have a passion for learning as they adapt to changing tech demands. This desire to learn more is also important for the more mundane day-to-day work—inevitably you’ll encounter issues you’ve never seen before and the only solution is to start researching potential answers.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Network_Administration.png","alias":"network-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 has all of the features of a modern, fully-fledged operating system: true multitasking, threads, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, loadable device driver modules, video frame buffering, and TCP/IP networking.\r\nMost people, however, refer to the operating system kernel, system software, and application software, collectively, as &quot;Linux,'' and that convention is used in this FAQ as well.\r\nLinux was written originally for 386/486/586-based PC's, using the hardware facilities of the 80386 processor family to implement its features. There are now many ports to other hardware platforms.\r\nThere are also Linux distributions specifically for mobile and handheld platforms. An API specification and developers kit for the Crusoe Smart Microprocessor developed by Transmeta Corporation is at <link http://www.transmeta.com/>http://www.transmeta.com/</link> The Linux kernel is distributed under the GNU General Public License.\r\n<span style=\"font-weight: bold;\">What Hardware Is Supported?</span>\r\nA minimal Linux installation requires a machine for which a port exists, at least 2Mb of RAM, and a single floppy drive. But to do anything even remotely useful, more RAM and disk space are needed.\r\nIntel CPU, PC-compatible machines require at least an 80386 processor to run the standard Linux kernel. Linux, including the X Window System GUI, runs on most current laptops.\r\n<span style=\"font-weight: bold;\">What are the duties of a Linux Administrator?</span>\r\nSystem Administration has become a solid criterion for an organization and institute that requires a solid IT foundation. Hence, the need for efficient Linux administrators is the requirement of the time. The job profile might change from each organization as there may be added responsibilities and duties to the role. Below are some duties of a Linux Administrator:\r\n<ul><li>Maintain all internet requests inclusive to DNS, RADIUS, Apache, MySQL, PHP.</li><li>Taking regular back up of data, create new stored procedures and listing back-up is one of the duties.</li><li>Analyzing all error logs and fixing along with providing excellent customer support for Webhosting, ISP and LAN Customers on troubleshooting increased support troubles.</li><li>Communicating with the staff, vendors, and customers in a cultivated, professional manner at all times has to be one of his characteristics.</li><li>Enhance, maintain and creating the tools for the Linux environment and its users.</li><li>Detecting and solving the service problems ranging from disaster recovery to login problems.</li><li>Installing the necessary systems and security tools.

The backup system administration is an integral part of data and IT system security structure. It is the backup process quality and method that determine whether in the case of a system failure or data loss it will be possible to maintain functionality and continuity of the enterprise’s operations. This is why careful creation of backup copies is so important.\r\nCreating backup copies may be burdensome and very expensive and time-consuming when you do it all by yourself. On the other hand, the automation of the process introduces a range of improvements, saves time and eliminate the risk of data loss. The copies are created automatically and are protected against interference by third parties.&nbsp; The network administrator is capable of remote backup system management, validity monitoring of created copies as well as retrieving lost information.","materialsDescription":" <span style=\"font-weight: bold;\">The need for backup: when will help out the backup scheme?</span>\r\n<span style=\"font-weight: bold;\">Data corruption</span>\r\nThe need to create a backup is most obvious in the case when your data may undergo damage - physical destruction or theft of the carrier, virus attack, accidental and/or illegal changes, etc.\r\nA working backup plan will allow you to return your data in the event of any failure or accident without the cost and complexity.\r\n<span style=\"font-weight: bold;\">Copying information, creating mirrors</span>\r\nA less obvious option for using the backup scheme is to automatically create copies of data not for storage, but for use: cloning and mirroring databases, web sites, work projects, etc.\r\nThe backup scheme does not define what, where and why to copy - use backup as a cloning tool.\r\n<span style=\"font-weight: bold;\">Test, training and debugging projects</span>\r\nA special case of data cloning is the creation of a copy of working information in order to debug, improve or study its processing system. You can create a copy of your website or database using the backup instructions to make and debug any changes.\r\nThe need for backing up training and debugging versions of information is all the more high because the changes you make often lead to data loss.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Backup_Administration.png","alias":"backup-administration"},"699":{"id":699,"title":"SAP Administration","description":" SAP Basis is the technical foundation that enables SAP applications to function.

Their responsibilities typically include configuring, monitoring, tuning and troubleshooting the environment, as well as scheduling and running the TMS.\r\nSAP Basis consultants generally provide technical support and high-level leadership for SAP systems. This typically includes establishing standards and requirements, evaluating and directing enhancements or upgrades, implementing processes for performance monitoring, and system configuration, design, and implementation.\r\nSAP offers technical certifications for various levels of SAP Basis administration. These create benchmarks that allow Basis professionals to demonstrate expertise in various tasks or functional areas. SAP certification classes or courseware are available from SAP and other vendors, and certifications are usually achieved after passing an exam.

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. John C. Reynolds rebuts this view, and argues that software development is entirely design work, and compares a manager who cannot program to the managing editor of a newspaper who cannot write.","materialsDescription":" <span style=\"font-weight: bold;\">What is a software project?</span>\r\nA software development project is a complex undertaking by two or more persons within the boundaries of time, budget, and staff resources that produce new or enhanced computer code that adds significant business value to a new or existing business process.\r\n<span style=\"font-weight: bold;\">What does a software development project manager do?</span>\r\nA software project manager is the most important person inside a team who takes the overall responsibilities to manage the software projects and plays an important role in the successful completion of the projects.

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"}},"companyUrl":"https://www.razeragency.com/","countryCodes":["GBR"],"certifications":[],"isSeller":true,"isSupplier":true,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Razer Agency","keywords":"","description":"Our agency revolutionizes the way IT recruitment is done, combining technical expertise, lightning-fast processes, and a global perspective to deliver unparalleled results.
