ADO.NET is a new programming model built upon the .NET Framework,
sharing a common type system, design patterns and naming conventions.

Provide a disconnected (offline) data architecture in addition to
supporting connected operation
Integrate tightly with XML
Interact with a variety of data sources through a common data
Optimize data source access
ADO.NET is designed to provide consistent access to data sources.
This is accomplished through ADO.NET data providers that provide
methods for connecting to data sources as well as retrieving,
manipulating, and updating data in both connected and disconnected
