This 3 day course descibes the use and application of AJAX. AJAX is an acronym for Asynchronous JavaScript and XML. It is a development technique for creating interactive web applications. Unlike classic web pages, which must load in their entirety if content changes, AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes.
