Ajax is a group of interrelated web development methods used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously (in the background) without interfering with the display and behavior of the existing page. Data is usually retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not needed (JSON is often used instead), and the requests do not need to be asynchronous.
Ajax is not one technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and to allow the user to interact with the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.(sources : http://en.wikipedia.org)
Although AJAX has a very tempting set of features, it is important to know when to use AJAX and when not to. The greatest advantage of AJAX over other scripts is that it remains hidden if the source is tried to be viewed. The only drawback is the slow loading which can still be compensated. If the page loading fails then it simply shows itself as a broken link. Thus evaluation before execution is the key to success.
At SilentDrifter Inc., all such mentioned and unmentioned uses and functions of AJAX are put to test. We look forward to innovative yet efficient modules that challenge and eventually enhance our skills. The aim is not only to create interactive web applications but intelligent web applications.
