What is ajax technology ?

"Ajax (shorthand for asynchronous JavaScript and XML) is a group of interrelated web development techniques used on the client-side to create interactive web applications.

With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.

The use of Ajax techniques has led to an increase in interactive or dynamic interfaces on web pages."

Ajax is a way of developing Web applications that combines:
*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

In the traditional Web application, the interaction between the customer and the server goes like this:
*Customer accesses Web application
*Server processes request and sends data to the browser while the customer waits
*Customer clicks on a link or interacts with the application
*Server processes request and sends data back to the browser while the customer waits
etc....
