Ajax (also known as AJAX), shorthand for "Asynchronous JavaScript and XML," is a web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is intended to increase the web page's interactivity, speed, and usability.
XML & XSLT
XML (Extensible Markup Language) a flexible text format for creating structured computer documents. It is a general-purpose specification for creating custom markup languages. XML's purpose is to aid information systems in sharing structured data, especially via the Internet to encode documents, and to serialize data.
XML provides a basic syntax that can be used to share information between different kinds of computers, different applications, and different organizations without needing to pass through many layers of conversion. All major browsers like Google Chrome, opera, Firefox have support for XML and XSLT.
JavaScript & JSON
JavaScript is a popular scripting language that is widely supported in web browsers and other web tools
A scripting programming language most commonly used to add interactive features to webpages.JavaScript can make web pages more animated and dynamic in terms of graphics and navigation. One of the most common graphic JavaScript effects is called a mouseover, and Javascript navigation is commonly created using drop-down menus. JavaScript is used in millions of Web pages to add functionality, validate forms, detect browsers, and much more

XHTML (or HTML) and CSS, for marking up and styling information. The DOM accessed with a client-side scripting language, especially ECMAScript implementations such as JavaScript and JScript, to dynamically display and interact with the information presented.
The XMLHttpRequest object is used to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server, and in other implementations, dynamically added <script> tags may be used.
XML is sometimes used as the format for transferring data between the server and client, although any format will work, including preformatted HTML, plain text, JSON and even EBML. These files may be created dynamically by some form of server-side scripting.

XML is designed to transport and store data.
With XML You Invent Your Own Tags.
XML Separates Data from HTML.
XML Simplifies Platform Changes, Data Sharing and Data Transport.
XML is Used to Create New Internet Languages like XHTML,WSDL, WAP and WML, RSS.
Application
XML's support for identity, storage and structure means it is possible to publish to the Web (as HTML) as well as to paper (as PDF) and to other formats (eg Braille, Audio, etc) from a single source document by using the appropriate stylesheets. XML is also very heavily used for enclosing or encapsulating information in order to pass it between different computing systems which would otherwise be unable to communicate. Weather services, e-commerce sites, blog newsfeeds, AJAX sites, and thousands of other data-exchange services use XML for data management and transmission, and the web browser for display and interaction
Application
Transform XML schema to another schema.
A food retailer may represent an order based on one schema while the manufacturer may represent it with another. With XSLT, a customer order taken by the retailer can be transformed into an order that matches the manufacturer's requirements.
Transform XML documents into HTML.
New Internet devices may not understand XML, but almost always will support HTML
XSLT transformations
Transform XML to HTML for devices such as handheld PCs, mobile phones, and
TV set-top boxes
Transform XML documents into PDF.
Printers do not understand HTML, but almost always accept the Package Definition Format (PDF).

Everyone can use JavaScript without purchasing a license
Application
Javascript is used for validation of WEB FORM input values to make sure that they will be accepted before they are submitted to the server. JavaScript can put dynamic text into an HTML page . It can respond to user actions quickly, making an application feel more responsive. Furthermore, JavaScript code can detect user actions which HTML alone cannot, such as individual keystrokes. Applications such as GMail take advantage of this: much of the user-interface logic is written in JavaScript. The wider trend of AJAX programming also exploits this strength.JavaScript can be used to detect the visitor's browser.
