The .NET Framework is designed to change dramatically the developer's current style of
developing applications, including the data access features. For the .NET applications,
the primary data access technology to be used would be ADO.NET — the latest addition
to the ADO model.
The ADO.NET Object Model is primarily divided into two levels:
§ Connected Layer: Consists of the classes that comprise the Managed
Providers
§ Disconnected Layer: Is rooted in the DataSet
This section describes both the Managed Providers and the DataSet.
