Today, in the World of AJAX and RIA , it is a very challenging decision for choosing or evaluating a AJAX or RIA(Rich Internet Applications) solutions, because the one can loose focus or misjudge priorities or the purpose of developing a solution , in This Article We are going to try to show the most distinctive requirements and product features in a top-down sequence, discussing the essential differences between technology options.




The focus is entirely on questions you should answer when evaluating RIA products. There is no assessment of specific products, because the individual features of products tend to obscure fundamental issues. Notice that RIA and AJAX are sometimes used as synonyms. This is not entirely correct: AJAX is short for “Asynchronous JavaScript And XML”, which essentially limits the term to the set of RIA solutions based on JavaScript. I will adhere to this latter definition, although I fully agree with authors who argue that the concepts proposed by AJAX are by no means limited to JavaScript .
