OLE DB is the database access interface technology used by MDAC. OLE DB providers can be created to access such simple data stores as a text file or spreadsheet, through to such complex databases as Oracle and SQL Server. However, because different data store technology can have different capabilities, OLE DB providers may not implement every ...
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 ...
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).
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 MDAC system component bundle, together with other database drivers, to simplify development in COM-aware languages (e.g. Visual Basic).
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. They can also ...
OLE 1.0, released in 1990, was an evolution of the original Dynamic Data Exchange (DDE) concept that Microsoft developed for earlier versions of Windows.While DDE was limited to transferring limited amounts of data between two running applications, OLE was capable of maintaining active links between two documents or even embedding one type of document within another.

Er, no. MDAC 1.0 is not known publicly as the OLE DB 1.1 SDK. This article This article is the only article which says something about MDAC 1.1. Give me one source from Microsoft itself about MDAC 1.1 please, if not then there is no MDAC 1.1! So when do we speak technically of a first release of MDAC? The moment OLE DB was combined with ODBC.
