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.
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .
The Microsoft OLE DB Provider for ODBC, or MSDASQL, was an OLE DB provider for allowing ActiveX Data Objects access to databases via any ODBC driver. Microsoft supplied several OLE-DB providers (for the Indexing Service, Active Directory , Jet, SQL Server, Oracle ( MSDAORA [ 28 ] ) and Internet Publishing), however unless otherwise directed ...
Each system has at least some features of an object–relational database; they vary widely in their completeness and the approaches taken. The following tables compare general and technical information; please see the individual products' articles for further information.

An example of a database abstraction layer on the language level would be ODBC that is a platform-independent implementation of a database abstraction layer. The user installs specific driver software, through which ODBC can communicate with a database or set of databases. The user then has the ability to have programs communicate with ODBC ...
A provider is a software component that interacts with a data source. 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 ...
PageAhead Software co-developed the first standards based ODBC driver with Microsoft in 1992, Simba.DLL. The first ODBC driver was included in Microsoft Windows 3.1, and has since been installed on over 30 million computers. [citation needed] ODBC is a widely used data access interface for relational database management systems RDBMS.
