AJAX - Asynchronous JavaScript + XML

A tecnologia AJAX parece ser muito interessante para sistemas com interface Web.

AJAX - Wikipedia, the free encyclopedia: "AJAX or Asynchronous JavaScript and XML is a term describing a web development technique for creating interactive web applications using a combination of:
HTML (or XHTML) and CSS for presenting information
The Document Object Model manipulated through JavaScript to dynamically display and interact with the information presented
The XMLHttpRequest object to exchange data asynchronously with the web server. (XML is commonly used, although any text format will work, including preformatted HTML, plain text, and JSON)
Like DHTML, LAMP, or SPA, AJAX is not a technology in itself, but a term that refers to the use of a group of technologies together. In fact, derivative/composite technologies based substantially upon AJAX, such as AFLAX are already appearing."
