Appendix B. ADO.NET Object Model

I l @ ve RuBoard

ADO.NET consists of the namespaces and classes that manage accessing backend databases. In total ADO.NET consists of five namespaces and hundreds of classes. We don't have room to list all the namespaces and classes so we will detail only the three most commonly used namespaces (System.Data, System.Data.OleDb, and System.Data.SqlClient) and only the most commonly used classes within those namespaces. Figure B.1 shows the ADO.NET architecture that includes the most commonly used classes.

Figure B.1. You will probably use these classes in ADO.NET.

If you need information about the namespaces or classes not listed here please refer to the reference that is included in the documentation for the .NET SDK.
