publicclass DbProviderMapping extends NamedConfigurationElement

Remarks

The Enterprise Library Data Access Application Block leverages the ADO.NET 2.0 provider factories. To determine what type of Database matches a given provider factory type, the optional DbProviderMapping configuration objects can be defined in the block's configuration section.

If a mapping is not present for a given provider type, sensible defaults will be used:

• For provider name "System.Data.SqlClient", or for a provider of type SqlClientFactory, the SqlDatabase will be used.
• For provider name "System.Data.OracleClient", or for a provider of type OracleClientFactory, the OracleDatabase will be used.
• In any other case, the GenericDatabase will be used.
