REST (Representational State Transfer) allows for distributed computing with data transactions available using HTTP, URLs and XML. What this means is that you can call information from a data source over HTTP, using a correctly formed URL and get your results delivered to you in XML format, which you can work with using something like ASP.net or PHP to format and display on a web page.Because URLs are central to how we use the web already, the URL-driven approach of REST makes accessing web services really easy to understand. In essence, you construct a URL where the parameters define the data you want, and the data store sends back the results as XML which you can the process and display as you wish. An example might look like this:http://domainabouttoys/webservices.aspx?toyname=disney&am...
