AJAX stands for Asynchronous Java script and XML. Ajax incidentally is not another programming language as most people understand it but is an innovative technology for developing better, faster and better interactive web applications. With AJAX, JavaScript can communicate directly with the server, using the JavaScript XML- Http -Request-object. With this object, JavaScript can exchange data with a web server, without reloading the page. AJAX employs asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages.
The AJAX technique makes Internet applications smaller, faster and more user-friendly. AJAX is a browser technology independent of web server software. Ajax is based on the web standards Java Script, XML, HTML and CSS. The web standards used in AJAX are well defined, and supported by all major browsers. AJAX applications are browser and platform independent. With AJAX, Internet applications can be made richer and more user-friendly. The chief advantage of switching to Ajax programming is that the developer can overcome the page loading requirements of HTML/HTTP-mediated web pages.
Ajax creates the necessary initial conditions for the evolution of complex, intuitive, dynamic, data-centric user interfaces in web pages. Web pages data are not tightly bound to data sources and must be first integrated into an HTML page format before they can be presented to user. Here, web pages have to be re-loaded each time a user needs to view different datasets. By using the XML-HTTP-Request- object to request and return data without a re-load, a programmer circumvents this requirement and makes the loosely coupled web page behave much like a tightly coupled application.
The chief advantage of Ajax programming is the vast improvement that is imparted to the user interface. Pages using Ajax behave more like a stand-alone application than a typical web page. With Ajax, the page can be updated dynamically, allowing a faster response to the user's interaction. Ajax has proved to be an important technology, helping make the web more interactive.
