ADO.NET provides consistent access to data sources such as
Microsoft SQL Server, as well as data sources exposed
through OLE DB and XML. Data-sharing consumer applications
can use ADO.NET to connect to these data sources and
retrieve, manipulate, and update data.

ADO.NET cleanly factors data access from data manipulation
into discrete components that can be used separately or in
tandem. ADO.NET includes .NET Framework data providers for
connecting to a database, executing commands, and retrieving
results. Those results are either processed directly, or
placed in an ADO.NET DataSet object in order to be exposed
to the user in an ad-hoc manner, combined with data from
multiple sources, or remoted between tiers. The ADO.NET
DataSet object can also be used independently of a .NET
Framework data provider to manage data local to the
application or sourced from XML.
