Microsoft Data Access Components (MDAC) 2.8 SP1 is a framework of interrelated Microsoft technologies that allows programmers a uniform and comprehensive way of developing applications that can access almost any data store. Its components include: ActiveX Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC). Some deprecated components are the Microsoft Jet Database Engine, MSDASQL (the OLE DB provider for ODBC), and Remote Data Services (RDS). Components like the Data Access Objects API and Remote Data Objects are now obsolete.
