What are ADO.net data services?

An ADO.net data service is a combination of the runtime and a web service through which the services are exposed. ADO.NET Data Services exposes data, represented as Entity Data Modal objects, via web services accessed over HTTP. The data can be addressed using URI. The ADO.net data service, when accessed via the HTTP GET method with such a URI, will return the data. The web service can be configured to return the data in either plain, XML, JSON.
