ADO.NET Data Services

ADO.NET Data Services consists of a combination of patterns and libraries that enable you to create and access data services for the Web or an intranet. ADO.NET Data Services exposes data as resources that are addressable by URIs. This enables you to access and change data by using the semantics of representational state transfer (REST), specifically the standard HTTP verbs of GET, PUT, POST, and DELETE.

ADO.NET Data Services uses the entity-relationship conventions of the Entity Data Model (EDM) to expose resources as sets of entities that are related by associations. ADO.NET Data Services enables you to expose data that originates from various sources. You can expose relational data as resources by defining a conceptual model by using the ADO.NET Entity Framework. You can also expose common language runtime (CLR) classes as resources.

ADO.NET Data Services uses internet standards for addressing and updating resources. These standards enable you to access these services from any client that can parse and access data that is transmitted over standard HTTP protocols. You can request and write data to resources by using well-known transfer formats: JavaScript Object Notation (JSON), a text-based data exchange format used extensively in AJAX application, and Atom, a set of standards for exchanging and updating data as XML.

ADO.NET Data Services also includes a set of client libraries, one for general .NET Framework client applications and another specifically for Silverlight-based applications. These client libraries provide an object-based programming model when accessing ADO.NET Data Services from platforms such as the .NET Framework and Silverlight.
