Using the OLE DB Persistence Provider: A Closer Look

Rowset persistence is implemented as an OLE DB service provider (Msdaprst.dll) that can be used by consumers to save rowsets to or load data from a locally persisted file. The provider is classified as a service component because, used with other service components, it adds functionality to existing data providers, allowing a disconnected rowset to be viewed and modified. The provider is invoked from ADO but is built on top of OLE DB.

For more information about using the Persistence Provider within ADO, see the "Microsoft OLE DB Persistence Provider" documentation in the ADO Programmer's Reference.
