Object Linking and Embedding Database (OLE DB) is an API designed by Microsoft that provides universal access to data of many types and formats. OLE DB connects to data sources using an OLE DB Provider, which is similar to an ODBC driver; it is a component written by an applications vendor or a third-party that allows OLE DB to communicate with a datastore.

The OLE DB connector allows you to connect to databases and applications that support OLE DB. You can use it to overcome the limitations of some ODBC drivers.
