AJAX

“Asynchronous JavaScript And XML”, otherwise known as AJAX, is a programming language that allows a web page to receive miniscule amounts of data from a web server without reloading the complete web page. Ajax works together with JavaScript. AJAX permits Web pages to be dynamic, interactive and behave as local applications. This combination of features is known as “rich client” applications. AJAX is similar to Dynamic HTML and allows synchronous and asynchronous access to remote services by using the XMLHTTPRequest object.

Before AJAX technology was developed, a request from the user for the retrieval of data would cause the entire Web page to be refreshed, resulting in very slow loading time and minimal interaction between the user and the web page. With the advent and success of AJAX, websites utilize the “remote scripting” of AJAX to better the functionality and waiting time of interactive and dynamic websites. The server exchanges small amounts of data without the user’s knowledge, increasing the speed, usability and navigation of web pages.

It is necessary for any IT professional programmer or developer to be familiar with the Ajax programming language. Online Training explaining the uses of Ajax, critique of Ajax, Challenges, Framework, basic overview of Web Services, XML, security aspects and the power of Ajax are discussed through tutorials in this section.

MainFrame

The term ‘MainFrame’ brings to mind a giant room of electronic parts that is a computer, referring to the original CPU cabinet in a computer of the mid-1960’s.

XML

A dialect of SGML (Standard Generalized Markup Language), XML (Extensible Markup Language), is not a programming language but a set of rules that structure data in a representational manner. XML rules are standard, leading the programmer to create documents that are automatically processed and generated for the World Wide Web. The breakdown of XML is as follows: Extensible, meaning user-defined tags, Markup, a collection of tags and XML Tags identifying data content.

Created in 1996, XML 1.0 was implemented for use in 1998 in association with the World Wide Web Consortium (W3C). Like HTML, XML is a markup language but it differs in its use of tags and attributes (markup). XML complies with cross-platform scripting language to create active information and interpret text-based code. XML language defines what the data is and HTML defines what it looks like (fonts and display).

Tutorials on the basic background information about XML, Elements in Document Type Definitions, Attributes, Entities and using XML with scripting languages are presented in ease to understand XML tutorials. Computer Sciences Engineers and IT Professionals are expected to be familiar with XML in addition to other open source technologies such as Java, Linux, Perl and MySQL. Software engineers, programmers and developers utilize XML in the development of web applications.

PHP

Hypertext Preprocessor or PHP as it is generally known, is a popular, Open Source all-purpose scripting language that is suited for Web development and embedded into HTML. PHP differs from Perl or C scripting languages by using special start and end tags that enclose the code, allowing the programmer to freely move in and out of “PHP mode”. PHP is distinguishable from client-side JavaScript because the code is executed on the server. The client receives the script results without being able to determine the underlying code. Configuring the web server to process all HTML files with PHP allows for safer and more secure scripting possibilities.

PHP is a simple and easy to use scripting language for a beginner developer but offers professional programming options and advanced features. PHP is focused on server-side scripting but has many more possibilities within designing, building, testing and deploying PHP sites. The syntax of PHP is similar to C, Java and Pearl and allows the web developer to create code for dynamically generated web pages in a quick and simple manner.

Although the main target field for PHP is server-side scripting, PHP can also be used for command line scripting and writing desktop applications. Tutorials include overviews and specific information on file manipulation, arrays, strings, functions, operators, variables, data types and installation for PHP. PHP is versatile and can be used with Linux, Unix, Microsoft Windows, Mac OS X and other operating systems. PHP supports many web servers and the developer can choose whether to use PHP as a procedural programming or object-oriented programming tool.

Data Recovery

Data Recovery is exactly what it sounds like - a way to recover important information that was lost from a computer crash, hard disk malfunction, or virus attack. No matter the scale, big corporation database recovery or single user retrieval of files from spontaneous “deleting”, data recovery is an important and necessary part of any operating system. Data Recovery software can be developed, installed and removed from existing systems to retrieve lost data or partial data and minimize damage caused to the system.

The goal of data recovery is perfection, as in, not losing a single byte of information. Unfortunately, this is next to impossible. One of the keys to success with data recovery is speed and accuracy. The programmer or IT professional that specializes in Data Recovery is a quick-thinking, problem solver who can work fast under pressure.

Information can be lost at a rapid pace and the time to recover the lost data requires extreme efficiency. Learning to back up your data can alleviate some of the pressure when data becomes lost or deleted.

Tutorials are made available in this section to help you learn the basics concepts and procedures on personal data recovery to more advanced tutorials such as understanding Electronic Vaulting, disk and tape storage for server based electronic business systems.

VBScript

Microsoft’s VBScript (Visual Basic Script) is a scripting language used to create dynamic and interactive web pages. VBScript is a subset of Visual Basic, a more developed scripting language, and is commonly used on the Web as a client side scripting language and server-side processing in ASPs (Active Server Pages). The interpreted script language VBScript is designed for Web Browser interpretation. VBScript is similar to scripting languages, including; Netscape’s JavaScript, Sun Microsystem’s Tcl, IBM’s Rexx and the UNIX-derived Perl. These scripting languages have been designed to be used as an extension for html language. A Web Browser receives the scripts for websites through web page documents that are then parsed and processed.

VBScript, like JavaScript (Jscript) is an ActiveX-enabled scripting language that connects to scripting hosts such as Internet Explorer and performs functions locally using the Windows Script Host (WSH). As a general rule, scripting languages are coded faster and simpler than in the compiled languages of C and C++. VBScript is structured and used with smaller programs with limited capability. Programmers, developers and IT professionals learning VBScript should also be familiar with ASP (Active Server Pages) and possess SQL Server commercial experience. Tutorials on VBScript include controlling script routines, working with objects, variables, forms and general VBScript information.

CSS

Cascading Style Sheets or CSS, as it is informally known, is the premier developer’s tool for designing high-end websites.

ASP.NET

ASP.NET is Microsoft’s middleware that is built on the .NET framework and it is the successor to Active Server Pages (ASP). Programmers using ASP.NET to utilize the .NET Framework class library and common language runtime (CLR). Web developers build dynamic websites, XML web services and powerful web applications using ASP.NET. Since ASP.NET is structured around CLR, programmers write code in ASP.NET using a variety of Microsoft .NET languages. ASP.NET dramatically increases performance by taking advantage of native optimization, caching services, early binding and just-in-time compilation. Web application developers can access the .NET Framework to use Data Access results, Messaging and class library.

It is the goal of Microsoft that ASP.NET completely replaces ASP. ASP.NET technology is slower but benefits the programmer and user because of its inherent stability that opens up design and development possibilities for the Internet. ASP.NET uses a text-based, hierarchical configuration system to simplify applying settings for web-based applications and the server environment.

Using our tutorials, programmers can learn to use ASP.NET to perform a multitude of everyday development tasks such as client authentication, site configuration, simple form submission and deployment.

Analysis Services

Microsoft Analysis Services is a collection of Online Analytical Processing (OLAP) and Data Mining services supplied in Microsoft SQL Server. ‘Data warehouse’ and ‘OLAP’ are often used interchangeably to describe two different elements of a decision support system.

Advances in data storage, transmission, database management tools and computerizing business processes
allow for constant technological development in data manipulation and analysis. Analysis Services provides managers the possibility to explore a cache of collected and current data, define business trends and patterns and mine data to make discerning business decisions.

An administrator operating the Microsoft SQL Server Analysis Services section of a data warehouse will face operational issues in the field. Analysis Services and its appropriately configured environment is applied and utilized in all aspects, from the development to the production environment. An Analysis Services administrator managing databases will have to operate and maintain Analysis Services within a preexisting IT and database infrastructure. Change control, operational issues, problem resolution, automation and tracking techniques will need to be understood and employed, in order to test for changes to an existing environment and database structure. An Analysis Systems administrator must actively anticipate capacity issues, problem solve and ensure availability of Analysis Services cubes.
