If you were to break down an Ajax request to its bare functionality, this is what you would be left with. In this scenario, a static XML, JSON, or text file residing on the same domain is requested by the XHR object through the GET method. It is then returned by the server to be handled by the client-side code that requested it. Take a look at to see the flow of a standard Ajax model.
This type of request can be beneficial if a web-savvy client or a developer is updating the requested file on the server, which is typically not the case, especially with large-scale applications. If this model is not going to meet your needs, the next approach has what this model is missing most: a database.
