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.
