OLE DB
Version 2.5

Purpose

OLE DB is a set of interfaces that expose data from a variety of sources by using the Component Object Model (COM). OLE DB interfaces provide applications with uniform access to data stored in diverse information sources. These interfaces support the amount of DBMS functionality appropriate to the data store, enabling the data store to share its data.
