Ajax (also called Asynchronous JavaScript and XML) is an innovative programming concept for the web development, a client-side script that focuses on communication from and to a server/database without any requirement for a postback or complete page refresh. Here, Data, content, and design are a total fusion to represent a complete architecture. A popular definition mentions Ajax as ‘the method of exchanging data with a server and updating parts of a web page without reloading the entire page’. It talks about the usage of the XmlHttpRequest objects for dynamic interaction with a web server through JavaScript. One ideal example is Google Maps, in which there is an instant display of required information as soon as you ask for it. With minimal lag time, Ajax helps build applications that display the information instantaneously and with no need to wait relentlessly for pages to refresh/reload.

Ajax merges the following components, for web development:
  • XML and XSLT for data interchange
  • JavaScript for tying it together
  • Page interaction through DOM
  • Presentation based on XHTML and CSS standards
  • Asynchronous data recovery through XMLHttpRequest

Salient Benefits of Ajax

  • Increased Speed:

The major motto of Ajax is to improvise the speed and performance of any web application, thereby increasing the usability and likeability of it.

  • Callbacks:

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.

  • User Friendliness:

Being much more responsive, quicker and user-friendly, Ajax web applications are bound to attract the clients on a higher scale.

  • Asynchronous Calls:

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.

In the case of the Ajax model, there is an Ajax engine involved in between the user and the server, which eliminates the to and fro from the user to the server and back. This Ajax engine is written in JavaScript and is in a hidden frame. It handles the user front by communicating with the user as well as handles the server front by itself. This way, the end-user barely faces a waiting period.
