The magic of AJAX has spread far and wide specially in its building strong roots for development of dynamic web applications. It also reflects changes in micro seconds thereby allowing time for reloading, improving usability, imparting faster accessibility and creation more web pages in lesser time. AJAX, also known as Asynchronous JavaScript And XML, is famous amongst all software developers and spreads to further network boundaries.

Ajax is a new breakthrough technology shifting web pages from HTML static pages to advance JavaScript and CSS enabled dynamic pages. AJAX is a free framework that helps in creation of interactive cross-platform web experiences.

Ajax is a more useful, dynamic and stronger technology that has accelerated the web world. It incorporates standardized presentations using XHTML and CSS; dynamic display and interaction using Document Object Model; asynchronous data retrieval using XMLHttpRequest and JavaScript, data interaction and manipulation using XML. AJAX uses java script technology, HTML pages make asynchronous call to the server from which it further fetches information that can be formatted as HTML, XML, and JAVA Script Object Notation (JSON).

AJAX is based on a variety of server side architecture to support the interaction model. It includes intermediate application layer, an Ajax engine that is added between the user and server that will further allow asynchronous user’s interaction with application.

This approach provides a host of benefits:

• Auto completion of form fields, better interaction and control with the usage of advanced controls.
• Real-time validation with server side validation of codes.
• Content mixtures from third parties application with your application.

Google Maps, Orkut, Google and Flickr are some of the ebst examples of AJAX application development.

Major challenges of Ajax

Ajax application development is facing a host of new challenges like XMLHttpRequest object is not a part of JavaScript technology specification, so it makes adaptability quite difficult for older browsers. It also acquires in-depth knowledge required to understand advanced technologies. You should remember that websites using Ajax technologies are not search engine friendly and they have a host of compatibility problems with different browsers.
