Data Source Object Interfaces

The following table shows the mandatory and optional interfaces defined by OLE DB for a data source object.

Interface	Required?	Implemented by OLE DB templates?
IDBCreateSession	Mandatory	Yes
IDBInitialize	Mandatory	Yes
IDBProperties	Mandatory	Yes
IPersist	Mandatory	Yes
IConnectionPointContainer	Optional	No
IDBDataSourceAdmin	Optional	No
IDBInfo	Optional	No
IPersistFile	Optional	No
ISupportErrorInfo	Optional	No

The data source object implements the IDBProperties, IDBInitialize, and IDBCreateSession interfaces through inheritance. You can choose to support additional functionality by inheriting or not inheriting from one of these implementation classes. If you want to support the IDBDataSourceAdmin interface, you must inherit from the IDBDataSourceAdminImpl class.
