Data Provider Data Flow
A data provider in the Microsoft .NET Framework enables a connection to a data source to retrieve and modify data from that data source. Data coming out of a .NET data provider can be used directly by an application or it can be redirected into an ADO.NET DataSet where it can be processed by other application methods such as XML processing.
The following figure shows the flow of data in and out of the data provider.
As shown in this figure, the .NET Data Provider uses an intermediate server called the Data Access Server to access Ingres databases.
For additional information on this server, see the chapter "Configuring the Data Access Server."
Note: The .NET Data Provider does not require Ingres Net for database connectivity. For best performance, the data provider directly communicates with the wire.
