Asynchronous Javascript and XML (Ajax)

Asynchronous JavaScript and XML (Ajax) is a design approach for creating highly interactive and responsive Web clients. Its adoption has quickly been made compulsory by the Internet user community.

Ajax, 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 makes a change. This is meant to increase the Web page's interactivity, speed, and usability.

DDIA utilizes Ajax through a series of techniques:

• XHTML, CSS, for marking up and styling information.
• The DOM accessed via JavaScript, to dynamically display and interact with the information presented.
• The XMLHttpRequest object to exchange data with the web server.
• XML is used for transferring formatted data back and forth to third party servers.
• JSON the JavaScript Object Notation is used to move raw data from the server to the JavaScript application on the fly and in a format that works effectively the native JavaScript architecture.
