AJAX isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful ways. This article introduces the AJAX methodologies for web application development..

The buzz that has been swarming the Internet is the term Ajax (Asynchronous JavaScript and XML). To my surprise, many developers still are not sure what this Ajax thing is. Hopefully I can educate those people that are still in the dark about this hot topic in the world of programming. Why is this Ajax thing so hot? Well the magic of it all is it spans every server side language out there. A PHP developer, a Java developer, and a .NET developer can all use this! This Ajax technology is not server side language specific so that is why there is great "hype." I can personally say that Ajax is not just hype. Judging by the responses I have gotten from here on the JavaRanch or out on my talks promoting Ajax in Action, it looks like Ajax is not going away, as some old timer programmers are wishing! I use it in production, and it's part of many applications that you may use on a daily basis.

It may be a surprise to some, but Ajax has been around for a long time; it's just that no one put a cleaning name to it until of late. And yes, Microsoft did implement it and others copied it (others copy Microsoft?) I am glad they did so this could take off. Ajax is supported by all of the major Web browsers now available.

Desktop applications have a richness and responsiveness that has seemed out of reach on the Web. The same simplicity that enabled the Web’s rapid proliferation also creates a gap between the experiences we can provide and the experiences users can get from a desktop application. That gap is closing with the coming up of AJAX.

The web application model follows this path way,  most user actions in the interface trigger an HTTP request back to a web server. The server does some processing — retrieving data, crunching numbers, talking to various legacy systems — and then returns an HTML page to the client. It’s a model adapted from the Web’s original use as a hypertext medium, but as fans of The Elements of User Experience know, what makes the Web good for hypertext doesn’t necessarily make it good for software applications.

Move into the world of the client side merging with the server and see how you can improve your users' experience. Remember to do it one control at a time and keep your code clean!
