Ajax

Asynchronous JavaScript and XML or Ajax, is a development technique GreenPages uses to create interactive web applications. Ajax makes web pages feel more responsive, increasing the user experience.

How Does Ajax Work?
Rather than having an entire web page reload each time a user requests a change, Ajax technology exchanges data with the server behind the scenes. Because Ajax holds most information in the engine itself, interaction between the application and the user occurs asynchronously and independently of any interaction with the server.

Ajax Breaks the Hour Glass
Therefore, with Ajax-driven applications, there is very little lag time. The page simply displays what the user requests. As a result, Ajax increases interactivity, functionality, speed, and usability.

Because Ajax is cross-platform, it can be used on many different operating systems and architectures. And because Ajax is based on open standards, it can be used with different web browsers.

Ajax incorporates the following technologies:

• XHTML and CSS standards-based presentation
• Interaction with the page through the DOM
• Data interchange with XML and XSLT
• Asynchronous data retrieval with XMLHttpRequest
• JavaScript to tie it all together

Ajax is technically sound, practical, and pragmatic for even the most complex applications. Ajax also enables companies to accommodate new business requirements as they arise. Simply put, Ajax enables GreenPages’ engineers to create web applications that effectively merge data, content, and design into a seamless whole.
