OLE DB and ADO

[This is preliminary documentation and subject to change.]

The Exchange 2000 Server handles Web Store events through the ExOLEDB COM server. Events are based on the OLE DB toolset. Although you do not need to write code with OLE DB, you will probably find it helpful to understand the concepts of OLE DB, specifically the concepts behind transactions and sessions.

The following list provides the concepts behind transactions and sessions:

• Some events run in the context of an OLE DB local transaction.
• The Web Store may be accessed using OLE DB (as provided by ExOLEDB).
• Some security concepts are based on OLE DB sessions.

Microsoft® ActiveX® Data Objects (ADO) can be used within your sinks to supplant almost all OLE DB programming. ADO is used extensively in the Programming Tasks and Examples section of this documentation.

Note   ExOLEDB is a core component of Exchange and is registered automatically with Exchange installation.
