Introduction to Ajax

What is Ajax ?

Ajax isn’t a single technology but a collection of several technologies that come together to form a powerful tool that will change the way people worked on web. It does away with the unnecessary delays experienced in web applications. Using Ajax users will no longer wait around while the application interacts with the server. As a matter of fact the user will no longer see the application go to the server at all.

The result… A fast and efficient web application that is free of refreshes and web page submissions.

How is Ajax different

An Ajax application eliminates the start-stop-start-stop nature of interaction on the Web by introducing an intermediary — an Ajax engine — between the user and the server. Instead of loading a webpage, at the start of the session, the browser loads an Ajax engine.

This engine is responsible for both rendering the interface the user sees and communicating with the server on the user’s behalf. The Ajax engine allows the user’s interaction with the application to happen asynchronously — independent of communication with the server. So the user is never staring at a blank browser window and an hourglass icon, waiting around for the server to do something.

Who is Using Ajax ?

Google is making a huge investment in developing the Ajax approach. All of the major products Google has introduced over the last year — Orkut, Gmail, the latest beta version of Google Groups, Google Suggest, and Google Maps — are Ajax applications.

Where to use Ajax ?

Ajax proves useful from most basic web applications to most complex ones.

Below are a few places in web applications where Ajax must be used:

· Form driven interaction
· Deep Hierarchical tree navigation
· User-user communication - Mail, message boards, groups etc.
· Voting/ rating submissions
· Filtering and data manipulation Text Auto complete
