Xcode is Apple’s IDE (Integrated Development Environment) for both Mac and iOS apps. Xcode is the graphical interface you'll use to write iOS apps. Xcode includes the iOS SDK, tools, compilers, and frameworks you need specifically to design, develop, write code, and debug an app for iOS. For native mobile app development on iOS, Apple suggests using the modern Swift programming language. It is important to note that Xcode only runs on Mac OS X and the only supported way to develop iOS apps. Like desktop software, iOS development software are designed using a range of programming languages and frameworks.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">iOS software development kit. </span>Mobile iOS app creation software requires access to software development kits (SDKs) that provide an environment through which programmers can design and test code in a simulated mobile environment. Some iOS SDK essentials are the Cocoa Touch frameworks that include the UIKit, GameKit, PushKit, Foundation Kit, and MapKit. These frameworks and others allow you manipulate the iPhone or iPad camera, add voice interaction using SiriKit, explore music with MusicKit, expand viewing and listening via AirPlay 2, and even add iMessage Business Chat to your application. iOS 11 added the power of machine learning with Core ML and augmented reality (AR) experiences with ARKit.\r\n<p id=\"Beta_Testing\" style=\" color:#232f3e; \"><span style=\"font-weight: bold; \">Beta Testing.</span> <span style=\"font-weight: normal; \">Once you have built and tested (using XCTest framework or iOS Unit test) your app, you can invite users to your apps and collect feedback using TestFlight prior to deploying to the App Store. This is a good time for testing Push Notifications, data storage using Core Data, and making network calls to 3rd party APIs. To get going, you simply upload a beta build of your app, and use iTunes Connect to add the name and email of testers. <br /></span></p>\r\n<p id=\"Beta_Testing\" style=\" color:#232f3e; \"><span style=\"font-weight: bold; \">Cloud Testing.</span><span style=\"font-weight: normal; \">Testing your iOS app on real devices is critically important since the performance of the real device, different operating system versions, modifications made by manufacturer and carriers firmware may lead to unexpected issues with your app. Testing on real device gives you a more accurate understanding of how your users interact with your app. On the other hand, obtaining physical devices for testing is a logistical challenge. This is where cloud testing comes into play. With cloud testing, you can test your application on real devices that are accessible on the cloud. <br /></span></p>\r\n<p id=\"Beta_Testing\" style=\" color:#232f3e; \"><span style=\"font-weight: bold; \">Deployment.</span> <span style=\"font-weight: normal; \">Once you have built, tested, and beta tested your iOS app, you can deploy to the App Store.

This contains a set of tools, resources and programming essentials within itself. It helps software/web/ mobile app developers to create new programs. This is a comprehensive solution for creating software or mobile app independently. These resources make development, deployment and debugging processes very simple. Choosing an IDE for iPhone app development is dependent on the budget, kind of programming language you prefer, etc. There are so many functionalities in an IDE that gives you a lot of benefits for app development.\r\nThe IDE makes strategies and streamlines the development phase for your entire team. It has many tools for automation, programming, debugging, compiling and for interpretation. There are three general types of IDE available. They are cloud-based, software as a service (SaaS) type and installing on the server type. IDE for iOS application development software is preferred bycompanies to reduce development time and costs. It helps in accurate testing and easy coding. Integration is also possible with these IDEs. It is as simple as a word processing program used by developers to create robust mobile applications.<br /> ","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_iOS_Software_Development.png","alias":"ios-software-development"},"597":{"id":597,"title":"Android Software Application","description":" Android software development is the process by which new applications are created for devices running the Android operating system. Google states that &quot;Android apps can be written using Kotlin, Java, and C++ languages&quot; using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some languages/programming tools allow cross-platform app support, i.e. for both Android and iOS. Third party tools, development environments and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, Bank of America etc. eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.\r\nAndroid was created by the Open Handset Alliance, which is led by Google. The early feedback on developing applications for the Android platform was mixed. Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. In December 2007, MergeLab mobile startup founder Adam MacBeth stated, &quot;Functionality is not there, is poorly documented or just doesn't work... It's clearly not ready for prime time.&quot; Despite this, Android-targeted applications began to appear the week after the platform was announced. The first publicly available application was the Snake game.\r\nA preview release of the Android SDK was released on November 12, 2007. On July 15, 2008, the Android Developer Challenge Team accidentally sent an email to all entrants in the Android Developer Challenge announcing that a new release of the SDK was available in a &quot;private&quot; download area. The email was intended for winners of the first round of the Android Developer Challenge. The revelation that Google was supplying new SDK releases to some developers and not others (and keeping this arrangement private) led to widely reported frustration within the Android developer community at the time.\r\nOn August 18, 2008, the Android 0.9 SDK beta was released. This release provided an updated and extended API, improved development tools and an updated design for the home screen. Detailed instructions for upgrading are available to those already working with an earlier release. On September 23, 2008, the Android 1.0 SDK (Release 1) was released. According to the release notes, it included &quot;mainly bug fixes, although some smaller features were added.&quot; It also included several API changes from the 0.9 version. Multiple versions have been released since it was developed.\r\nOn December 5, 2008, Google announced the first Android Dev Phone, a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. It was a modified version of HTC's Dream phone. While developers can use regular consumer devices to test and use their applications, some developers may choose a dedicated unlocked or no-contract device.\r\nAs of July 2013, more than one million applications have been developed for Android, with over 25 billion downloads. A June 2011 research indicated that over 67% of mobile developers used the platform, at the time of publication. Android smartphone shipments are forecast to exceed 1.2 billion units in 2018 with an 85% market share.","materialsDescription":" <span style=\"font-weight: bold;\">Where does Android come from?</span>\r\nIt comes from Google, who actually acquired Android in 2005 (no, Google didn't invent it). The search giant performs regular updates along with an annual major update.\r\nThe operating system is based on the Linux kernel – if you have friends who work in IT, you may have heard of it. This is the GNU / Linux operating system based structure, which is a unix type system (portable operating system, multitasking and multi-user). The Linux kernel is one of the most prominent examples of free software.\r\n<span style=\"font-weight: bold;\">Why does Android look different on each phone?</span>\r\nAndroid doesn't look different on every device, but it does have a number of different versions. Android is open-source, which means that manufacturers are free to customize the software and make it their own.\r\nThe 'purest' version of Android is often referred to as 'stock Android' and it's often preferred by the Android community: it's the original software as Google intended.\r\nOther user interfaces (UI) include Samsung's TouchWiz, Sony's Xperia, and Huawei's Emotion. See what they all look like in our Android UI comparison.\r\n<span style=\"font-weight: bold;\">What are the advantages of Android?</span>\r\nChoice. For example, if you want iOS, you have a choice of iPhone, iPhone or iPhone. If you go for Android there are stacks of great devices to choose from, from cheap and cheerful handsets to really impressive flagships. Those flagships are often cheaper than the equivalent Apple devices, too.\r\nAndroid’s choice isn’t just about hardware. It’s about everything else too. Android is incredibly easy to customize, both in terms of how it looks and how it works, and the various app stores aren’t as tightly controlled as its rivals’ stores, like Apple.\r\n<span style=\"font-weight: bold;\">What’s with the candy names?</span>\r\nEach new version of Android gets a code name based on consecutive letters of the alphabet. The most recent version is known as Marshmallow because it is the Android M release. Previous versions have included Lollipop, KitKat, Jelly Bean and Gingerbread.\r\n<span style=\"font-weight: bold;\">What’s the best thing about Android?</span>\r\nOptions, many options. With Android, you have hundreds of gadgets at your disposal, the cheapest, the most expensive and innovative market. Android is also incredibly customizable, both in their roles, as in his appearance. You can really make a unique mobile experience for yourself with this OS.\r\n<span style=\"font-weight: bold;\">What’s the worst thing about Android?</span>\r\nGetting updates. In many cases, manufacturers don’t seem to care about providing software updates for devices they’ve already sold you. Even when they do provide updates they take their sweet time about it.

If the company has its own website, then it:\r\n<ul><li>facilitates potential customers and partners access to information about themselves;</li><li>attracts the target audience from the Internet;</li><li>significantly increases market coverage;</li><li>increases brand awareness;</li><li>facilitates communication both with partners and with the target audience;</li><li>improves customer feedback;</li><li>increases customer loyalty.</li></ul>\r\nHowever, the main advantage of owning a website, of course, is that it helps to significantly increase sales, and, consequently, profit. In general, now having a website is almost a prerequisite for successful business development.\r\nComputers, smartphones, tablets, other mobile devices, and the Internet have penetrated all spheres of our lives. A variety of mobile devices are especially popular, and that is why it is no longer possible to limit oneself to a PC version of a site. The website version for the PC is bad for mobile devices, and this, as you might guess, negatively affects sales and profits. If the site is uncomfortable to use, then the potential client will not rack their brains, but simply use the services of competitors. The vast majority will not even try to find something on the site if it is not adapted for mobile devices.\r\nA separate mobile version of the site is a site specifically designed for mobile users. As a rule, a mobile version of a site is hosted on a dedicated subdomain.\r\nThe mobile version of the site, in most cases, is simply a greatly reduced version of the site for the PC. Only those functions that, according to the developers, maybe needed by those users who access the site with a smartphone or tablets, are left on the mobile site.\r\nThe mobile version of the site is good in that it does not depend on the main one, can be easily changed and edited, loads quickly is quite convenient for users, and also has the option of switching to the main version of the site.","materialsDescription":" <span style=\"font-weight: bold;\">What’s a mobile website?</span>\r\nMobile devices have transformed the way we live, putting the digital world at our fingertips 24 hours a day, wherever we are.\r\nThis means establishing your mobile presence is more important now than ever as you have the opportunity to put your business in the pockets of your consumers and create more meaningful interactions with your users. Almost 80% of people use smartphones to search the internet, so if your business is lacking a mobile website or app, you are missing out on a huge market opportunity.\r\nThere are two types of mobile development – responsive mobile sites and mobile applications. We build easy to use, intuitive and responsive mobile apps and websites, designed for optimization across all devices to keep you ahead of your competitors.\r\nA mobile website is a website with a responsive, fluid design, that is user-friendly on multiple devices and web browsers. A study conducted by Google and Galaxy in June 2015 found that 74% of Australians rely on their phones at least as much as they rely on desktops when searching for information, ideas or advice. This is when responsive design plays a huge role.\r\n<span style=\"font-weight: bold;\">Why do I need a mobile website?</span>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Mobile traffic has taken over</span></span>\r\nAs mobile traffic has taken over desktop traffic in 2015, more and more people only browse the internet on mobile phones.

For a long time, Windows was the dominating operating system of the nineties.\r\nWhy Should You Use Mac OS X in App Development? A reason for this system’s stagnation in progress is the brand’s fear in offending its corporate clients; therefore every tech change has to be introduced painfully slowly so as to be assimilated by its clients.\r\nApple, on the other hand, has slowly crept up and overtaken Windows and other operating systems primarily because they are not afraid of taking giant leaps. Their “it’s our way or the high way” approach to their operating system has enabled them to make significant improvements in their software, which other operating systems are almost incapable of attaining.\r\nMAC OS X software is essentially a two-layered system. Its impressive GUI sits on top of a UNIX core, and UNIX is notorious for its impressive security features. UNIX makes it’s nearly impossible to install a Trojan or a virus to the system unless the user gives it root access to the system by essentially typing in the admin password into the system.\r\nThe beauty of MAC OS X built-in firewall is that it operates out the box, while at the same time being highly flexible. While MAC users should ideally remain vigilant about foreign files and consequentially never allow them into the system by giving them an admin pass, they then do not need special software to block out these viruses.\r\nMAC OS interface is simple, you can pin as many apps as possible to dock at the bottom of your screen, plus they are always available to you. Besides this, you can run multiple desktops, make use of your iCloud chain to decipher your credit card information, share various files wirelessly through Airdrop, and still monitor the operating system via a set of in-built high-grade utility tools.\r\nThe system also has a rapid start-up resume time. All this is essentially made possible by MAC OS powerful stability. Even though systemic degradation is expected over time, as is the case with just about every operating system, the rate is significantly reduced on MAC products and freezing and crashing are not a common everyday occurrence as is the case with a few operating systems.\r\nMAC’s impressive reliability can be primarily attributed to the fact that the operating system was built from the ground up. Apple essentially controls the production of its software and hardware products from start to finish, and so every part of the system is designed and tested out to work cohesively together.\r\nThose who complain that Apple forces its consumers to use its proprietary software couldn’t be more misguided. MAC OS automatically recognizes and works well with other Apple products including iPads, iPhones, etc.","materialsDescription":"<span style=\"font-weight: bold;\">What is Mac OS X?</span>\r\nMac OS X is an operating system created by Apple for Mac computers (the first version was introduced in 2001), which replaced the then outdated Mac OS 9.\r\nThis is a POSIX-compatible system, that is, all Unix operations can be performed in it. Built on the basis of the XNU core with the Aqua graphical interface.\r\nStarting with version 10.8 it is called OS X.\r\n<span style=\"font-weight: bold; \">What are the advantages of macOS?</span>\r\n<span style=\"font-style: italic; \">Fewer virus attacks:</span>\r\nAs macOS is the second most used operating system and has fewer active users so it has fewer virus attacks also. The other reason for virus safety is its UNIX relationship which is more secure than Windows OS.\r\n<span style=\"font-style: italic; \">Good customer support:</span>\r\nMac users get a good response from their support team as compared to other operating systems. Apple has skilled engineers which help the user in fixing the issues in their hardware and software.\r\n<span style=\"font-style: italic; \">Similar GUI for all the products:</span>\r\nmacOS has the same graphical user interface (GUI) as found in other Apple products like iPhone and tablets. Users feel comfortable in using macOS if they shifted from other Apple products.\r\n<span style=\"font-style: italic; \">Performance and long life:</span>\r\nAs Apple makes both hardware and software so it’s hardware communication is very efficient and it improves performance. The operating system and hardware work great. Apple computer has a longer life than other computers. The battery timing of mac laptops is also longer.\r\n<span style=\"font-style: italic; \">Default apps:</span>\r\nIf you install Windows then it comes with pre-installed apps that slow down your computer e.g. Onedrive slows your computer. But this is not the case with macOS, it comes with powerful apps which don’t affect the performance of your system. Some of the pre-installed apps of macOS are iPhoto and iMovie.\r\n<span style=\"font-style: italic; \">Support NTFS and FAT:</span>\r\nmacOS support Windows file system formats including both NTFS and FAT.\r\n<span style=\"font-style: italic; \">Can run Windows:</span>\r\nYou can run the Windows operating system if you have macOS installed by using Bootcamp or parallels software.\r\n<span style=\"font-weight: bold; \">What are the disadvantages of macOS?</span>\r\n<span style=\"font-style: italic; \">Expensive:</span>\r\nThe minimum cost of a Mac PC is higher than $1000. You can get a good Windows PC at $1000 with more hardware specifications.\r\n<span style=\"font-style: italic; \">Fewer games and software:</span>\r\nMost game developers prefer to make games for the Windows OS because they have more percentages of users. Mac users have fewer games available. Also, mac computers have low graphics capability to run high graphics games. There is some software that is available for Windows and not available for mac users e.g. adobe premiere pro etc.\r\n<span style=\"font-style: italic; \">No hardware customization:</span>\r\nIf you buy any Mac computer/laptop then you cannot change its hardware parts like processor, graphics card, etc. For some mac computers, you can change hardware and RAM but it is not for all mac computers. It is also not possible to change other hardware accessories like internal computer parts, the only choice you have is to buy a new mac computer. On every major release of your operating system you have to change your computer else 50% of your operating system features not work.\r\n<span style=\"font-style: italic; \">Windows cannot read the macOS file system:</span>\r\nmacOS can read NTFS and FAT Windows format but Windows cannot read the macOS file system. You need to install 3rd party software in Windows to do so. Some other software like footnotes has compatibility issues while moving files from macOS to Windows.\r\n<span style=\"font-style: italic; \">Less hardware used:</span>\r\nThe new version of macOS computer supports fewer USB ports and they also not shipped with CD/DVD writer.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_MacOS_Development.png","alias":"macos-development"},"605":{"id":605,"title":"Java Development","description":" Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client-server web applications, with a reported 9 million developers.\r\nJava was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1995 as a core component of Sun Microsystems' Java platform. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GNU General Public License. Meanwhile, others have developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets).\r\nThe latest versions are Java 13, released in September 2019, and Java 11, a currently supported long-term support (LTS) version, released on September 25, 2018; Oracle released for the legacy Java 8 LTS the last free public update in January 2019 for commercial use, while it will otherwise still support Java 8 with public updates for personal use up to at least December 2020. Oracle (and others) highly recommend uninstalling older versions of Java because of serious risks due to unresolved security issues. Since Java 9 (and 10 and 12) is no longer supported, Oracle advises its users to immediately transition to the latest version (currently Java 13) or an LTS release.","materialsDescription":"<span style=\"font-weight: bold; \">What is Java technology and what is its application?</span>\r\nJava is a programming language and computing platform that was first launched by Sun Microsystems in 1995.

In addition, the Java virtual machine was optimized - since 2000, the HotSpot virtual machine has been used for this. As of February 2012, Java 7 code is approximately 1.8 times slower than C code.\r\nSome platforms offer hardware runtime support for Java.

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

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.

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

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!

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

Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.\r\nRuby on Rails' emergence in the 2000s greatly influenced web app development, through innovative features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails' influence on other web frameworks remains apparent today, with many frameworks in other languages borrowing its ideas, including Django in Python, Catalyst in Perl, Laravel and CakePHP in PHP, Phoenix in Elixir, Play in Scala, and Sails.js in Node.js.\r\nRuby on Rails is intended to emphasize Convention over Configuration (CoC), and the Don't Repeat Yourself (DRY) principle.\r\n&quot;Convention over Configuration&quot; means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table &quot;products sold&quot;, that the developer needs to write code regarding these names. Generally, Ruby on Rails conventions lead to less code and less repetition.\r\n&quot;Don't repeat yourself&quot; means that information is located in a single, unambiguous place. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions. Instead, Ruby on Rails can retrieve this information from the database based on the class name.\r\n&quot;Fat models, skinny controllers&quot; means that most of the application logic should be placed within the model while leaving the controller as light as possible.","materialsDescription":" <span style=\"font-weight: bold;\">What is Ruby on Rails?</span>\r\nRails is a development tool that gives web developers a framework, providing structure for all the code they write.

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.

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.

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 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.

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

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.

The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals (user-centered design).\r\nGood user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design and typography are utilized to support its usability, influencing how the user performs certain interactions and improving the aesthetic appeal of the design; design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs.\r\nInterface design is involved in a wide range of projects from computer systems, to cars, to commercial planes; all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge. As a result, designers tend to specialize in certain types of projects and have skills centered on their expertise, whether it is a software design, user research, web design, or industrial design.","materialsDescription":" <span style=\"font-weight: bold;\">What is a Graphical User Interface?</span>\r\nThe graphical user interface, developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple’s Macintosh and Microsoft’s Windows operating systems, was designed as a response to the problem of inefficient usability in early, text-based command-line interfaces for the average user.\r\nGraphical user interfaces would become the standard of user-centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bars, windows, tabs, menus, cursors, and the mouse pointing device. Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities.\r\n<span style=\"font-weight: bold;\">How Does a Graphical User Interface Work?</span>\r\nGraphical user interface design principles conform to the model–view–controller software pattern, which separates internal representations of information from the manner in which information is presented to the user, resulting in a platform where users are shown which functions are possible rather than requiring the input of command codes. Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task.\r\nThe appearance, or “skin,” of an operating system or application software may be redesigned at will due to the nature of graphical user interfaces being independent from application functions. Applications typically implement their own unique graphical user interface display elements in addition to graphical user interface elements already present on the existing operating system. A typical graphical user interface also includes standard formats for representing graphics and text, making it possible to share data between applications running under common graphical user interface design software.\r\nGraphical user interface testing refers to the systematic process of generating test cases in order to evaluate the functionality of the system and its design elements. Graphical user interface testing tools, which are either manual or automated and typically implemented by third-party operators, are available under a variety of licenses and are supported by a variety of platforms. Popular examples include: Tricentis Tosca, Squish GUI Tester, Unified Functional Testing (UFT), Maveryx, Appium, and eggPlant Functional.\r\n<span style=\"font-weight: bold;\">Graphical User Interface Examples</span>\r\nSketchpad, believed to be the first graphical computer-aided design program, was developed in 1962 by Ivan Sutherland while he was at MIT, and consisted of a light pen that enabled users to create and manipulate objects in engineering drawings in real-time with coordinated graphics.\r\nModern operating systems and graphical user interfaces are incorporated into nearly every interactive application, such as ATMs, self-service checkouts, airline self-ticketing and check-in, video games, smartphones, and desktops. Some popular, modern graphical user interface examples include Microsoft Windows, macOS, Ubuntu Unity, and GNOME Shell for desktop environments, and Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS, and Firefox OS for smartphones.\r\n<span style=\"font-weight: bold;\">Advantages of Graphical User Interfaces</span>\r\nThe advantage of a graphical user interface is a stark improvement in useability for the average person. The features of a graphical user interface leverage familiar metaphors, such as drag-and-drop for transferring files, and use familiar icons, such as a trash bin for deleted files, creating an environment in which computer operations are intuitive and easily mastered without any prior practice or knowledge of computing machinery or languages. Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_User_Interface_Development.png","alias":"user-interface-development"},"669":{"id":669,"title":"MySQL Development","description":" MySQL is an open-source relational database management system (RDBMS).

In 2010, when Oracle acquired Sun, Widenius forked the open-source MySQL project to create MariaDB.\r\nMySQL is a component of the LAMP web application software stack (and others), which is an acronym for Linux, Apache, MySQL, Perl/PHP/Python. MySQL is used by many database-driven web applications, including Drupal, Joomla, phpBB, and WordPress. MySQL is also used by many popular websites, including Facebook, Flickr, MediaWiki, Twitter, and YouTube.\r\nMySQL is written in C and C++. Its SQL parser is written in yacc, but it uses a home-brewed lexical analyzer. MySQL works on many system platforms, including AIX, BSDi, FreeBSD, HP-UX, eComStation, i5/OS, IRIX, Linux, macOS, Microsoft Windows, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, OS/2 Warp, QNX, Oracle Solaris, Symbian, SunOS, SCO OpenServer, SCO UnixWare, Sanos and Tru64.

Oracle and IBM tend to battle for the mid-range database market on Unix and Linux platforms, while Microsoft dominates the mid-range database market on Microsoft Windows platforms. However, since they share many of the same customers, Oracle and IBM tend to support each other's products in many middleware and application categories (for example WebSphere, PeopleSoft, and Siebel Systems CRM), and IBM's hardware divisions work closely with Oracle on performance-optimizing server-technologies (for example, Linux on IBM Z).

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.

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. Architecture gives the ability to communicate about design decisions before the system is implemented when they are still relatively easy to adapt.</li><li><span style=\"font-style: italic;\">It helps in risk management.</span> Software architecture helps to reduce risks and the chance of failure.</li><li><span style=\"font-style: italic;\">It enables cost reduction.</span> Software architecture is a means to manage risk and costs in complex IT projects.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Architecture_Design.png","alias":"software-architecture-design"},"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"},"842":{"id":842,"title":"Chatbot Development","description":"A chatbot is a piece of software that conducts a conversation via auditory or textual methods. Such programs are often designed to convincingly simulate how a human would behave as a conversational partner, although as of 2019, they are far short of being able to pass the Turing test. Chatbots are typically used in dialog systems for various practical purposes including customer service or information acquisition. Some chatbots use sophisticated natural language processing systems, but many simpler ones scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database.\r\nThe term &quot;ChatterBot&quot; was originally coined by Michael Mauldin (creator of the first Verbot, Julia) in 1994 to describe these conversational programs. Today, most chatbots are accessed via virtual assistants such as Google Assistant and Amazon Alexa, via messaging apps such as Facebook Messenger or WeChat, or via individual organizations' apps and websites. Chatbots can be classified into usage categories such as conversational commerce (e-commerce via chat), analytics, communication, customer support, design, developer tools, education, entertainment, finance, food, games, health, HR, marketing, news, personal, productivity, shopping, social, sports, travel and utilities.\r\nBeyond chatbots, Conversational AI refers to the use of messaging apps, speech-based assistants and chatbots to automate communication and create personalized customer experiences at scale.\r\nThe process of building, testing and deploying chatbots can be done on cloud-based chatbot development platforms offered by cloud Platform as a Service (PaaS) providers such as Oracle Cloud Platform SnatchBot and IBM Watson. These cloud platforms provide Natural Language Processing, Artificial Intelligence and Mobile Backend as a Service for chatbot development.\r\nSome Companies like Microsoft Azure and AARC are currently providing their Bot Engines through which chatbot Platforms or Software can be developed.","materialsDescription":"New tools designed to simplify the interaction between humans and computers have hit the market: Chatbots or Virtual Assistants. In banking, chatbots and virtual assistants are some of the industry’s newest tools designed to simplify the interaction between humans and computers.\r\n<span style=\"font-weight: bold;\">What is a chatbot?</span>\r\nA chatbot is artificial intelligence (AI) software that can simulate a conversation (or a chat) with a user in natural language through messaging applications, websites, mobile apps or through the telephone.\r\n<span style=\"font-weight: bold;\">Why are chatbots important?</span>\r\nA chatbot is often described as one of the most advanced and promising expressions of interaction between humans and machines. However, from a technological point of view, a chatbot only represents the natural evolution of a Question-Answering system leveraging Natural Language Processing (NLP). Formulating responses to questions in natural language is one of the most typical examples of Natural Language Processing applied in various enterprises’ end-use applications.\r\n<span style=\"font-weight: bold;\">How does a chatbot work?</span>\r\nThere are two different tasks at the core of a chatbot:\r\n<ol><li>user request analysis</li><li>returning the response</li></ol>\r\nUser request analysis: this is the first task that a chatbot performs. It analyzes the user’s request to identify the user intent and to extract relevant entities.\r\nThe ability to identify the user’s intent and extract data and relevant entities contained in the user’s request is the first condition and the most relevant step at the core of a chatbot: If you are not able to correctly understand the user’s request, you won’t be able to provide the correct answer.\r\nReturning the response: once the user’s intent has been identified, the chatbot must provide the most appropriate response for the user’s request. The answer may be:\r\n<ul><li>a generic and predefined text;</li><li>a text retrieved from a knowledge base that contains different answers;</li><li>a contextualized piece of information based on data the user has provided;</li><li>data stored in enterprise systems;</li><li>the result of an action that the chatbot performed by interacting with one or more backend application;</li><li>a disambiguating question that helps the chatbot to correctly understand the user’s request.</li></ul>\r\n<span style=\"font-weight: bold;\">In what is the benefit of chatbots?</span>\r\nChatbot applications streamline interactions between people and services, enhancing the customer experience. At the same time, they offer companies new opportunities to improve the customer's engagement process and operational efficiency by reducing the typical cost of customer service.\r\nTo be successful, a chatbot solution should be able to effectively perform both of these tasks. Human support plays a key role here: Regardless of the kind of approach and the platform, human intervention is crucial in configuring, training and optimizing the chatbot system.\r\n<span style=\"font-weight: bold;\">Which chatbot application is right for you?</span>\r\nThere are different approaches and tools that you can use to develop a chatbot. Depending on the use case you want to address, some chatbot technologies are more appropriate than others. In order to achieve the desired results, the combination of different AI forms such as natural language processing, machine learning, and semantic understanding may be the best option.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Chatbot_Development.png","alias":"chatbot-development"}},"companyUrl":"https://sprigstack.com/erp-development-services","countryCodes":["IND","USA"],"certifications":[],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Sprigstack","keywords":"","description":"<p><span>SprigStack is a reputable IT consulting and software development company renowned for its extensive experience of over 7 years in providing a diverse range of services.
