===OLE DB-to-ODBC bridges===
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 (computer science)|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. Microsoft ships one, MSDASQL.DLL, as part of the [[Microsoft Data Access Components|MDAC]] [[system component bundle]], together with other database drivers, to simplify development in COM-aware languages (e.g. [[Visual Basic]]). Third parties have also developed such, notably OpenLink Software whose 64-bit OLE DB Provider for ODBC Data Sources filled the gap when Microsoft initially deprecated this bridge for their 64-bit OS.<ref name="msdasql">''Microsoft'', "Data Access Technologies Road Map", Deprecated MDAC Components, ''Microsoft'' [http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ado270/htm/mdrefodbcprovspec.asp "ADO Programmer's Guide" Appendix A: Providers, Microsoft OLE DB Provider for ODBC], retrieved July 30, 2005.  {{webarchive |url=https://web.archive.org/web/20011005101137/http://msdn.microsoft.com/library/default.asp?url=%2Flibrary%2Fen-us%2Fado270%2Fhtm%2Fmdrefodbcprovspec.asp |date=2001 October 5 }}</ref>  (Microsoft later relented, and 64-bit Windows starting with [[Windows Server 2008]] and [[Windows Vista SP1]] have shipped with a 64-bit version of MSDASQL.)
