DbProviderFactories (ADO.NET)

The System.Data.Common namespace provides classes for creating DbProviderFactory instances to work with specific data sources. When you create a DbProviderFactory instance and pass it information about the data provider, the DbProviderFactory can determine the correct, strongly typed connection object to return based on the information it has been provided.

Each .NET Framework data provider that exposes a DbProviderFactory registers configuration information and a provider string in the machine.config file. Data providers with registered factory classes in the .NET Framework include System.Data.Odbc, System.Data.OleDb, System.Data.SqlClient, System.Data.SqlServerCe, and System.Data.OracleClient.
