Appendix A. ADO.NET 2.0
ADO.NET is a set of classes that gives .NET applications access to relational, XML, and application data. The classes let you connect to data sources such as SQL Server and Oracle, as well as to data sources exposed through OLE DB and ODBC, and XML data. After you connect to these data sources, the ADO.NET classes let you retrieve, manipulate, and update data.
This appendix describes the new functionality, support, and features in ADO.NET 2.0.
