OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle, Microsoft SQL Server, Sybase ASE, and many others. It can also provide access to hierarchical data stores such as ...
OLE DB 2.1; the OLE DB Provider for ODBC, SQL Server and Oracle; JRO 2.1; a Jet driver; RDO. [41] This version had security vulnerabilities whereby an unchecked buffer could allow an elevated privileges attack. This was found some time later and it affected MDAC 2.1, 2.5 and 2.6 and was addressed in a later patch [42]
An OLE DB-ODBC bridge consists of an OLE DB Provider which uses the services of an ODBC driver to connect to a target database. This provider translates OLE DB method calls into ODBC function calls. Programmers usually use such a bridge when a given database lacks an OLE DB provider, but is accessible through an ODBC driver.
ADO.NET data providers are analogous to ODBC drivers, JDBC drivers, and OLE DB providers. ADO.NET providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle Database , Microsoft SQL Server , MySQL , PostgreSQL , SQLite , IBM Db2 , Sybase ASE , and many others.
SQL Server Native Client is used under the hood by SQL Server plug-ins for other data access technologies, including ADO or OLE DB. The SQL Server Native Client can also be directly used, bypassing the generic data access layers. [35] On November 28, 2011, a preview release of the SQL Server ODBC driver for Linux was released. [36]
In computing, Microsoft's ActiveX Data Objects (ADO) comprises a set of Component Object Model (COM) objects for accessing data sources. A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner).

Just over two years later, in 1998, Microsoft released OLAP Services as part of SQL Server 7. OLAP Services supported MOLAP, ROLAP, and HOLAP architectures, and it used OLE DB for OLAP as the client access API and MDX as a query language. It could work in client-server mode or offline mode with local cube files. [3]
