ADO.NET Data Adapters
The following topics provide information about ADO.NET data-adapter objects and how to work with them. Adapters are used to exchange data between a data source and a dataset.
In the previous version of Visual Studio, data adapters were used for communicating between an application and a database. While data adapters are still a main component of .NET Framework Data Providers (ADO.NET), TableAdapters are designer-generated components that simplify the process of moving data between your application and a database. For more information on working with TableAdapters, see TableAdapter Overview.
