Ajax merges the following components, for web development:
- XML and XSLT for data interchange
- Page interaction through DOM
- Presentation based on XHTML and CSS standards
- Asynchronous data recovery through XMLHttpRequest
Salient Benefits of Ajax
The major motto of Ajax is to improvise the speed and performance of any web application, thereby increasing the usability and likeability of it.
Ajax works with a mechanism in which there is a to and fro trip to the server saving the data without posting the full page back to the server. This callback feature minimizes the network utilization and hence gives out quicker and improvised application features. Due to callbacks, there is no need to process all the form elements, only necessary data has to be sent.
Being much more responsive, quicker and user-friendly, Ajax web applications are bound to attract the clients on a higher scale.
Since Ajax lets you make asynchronous calls to a web server, it facilitates the client browser by not waiting for the entire set of data to arrive.
Comparison of Traditional and Ajax Web Application Model
The traditional model talks about the majority of the user activities triggering an HTTP request back to the webserver and thereby, the server returning the HTML page to the client after doing some processing. Technically this works fine but does not give out a favorable user experience. There is a lot of wait time involved for the end-user.
