Lesson 22. Using OLE DB

This chapter takes a look at one of Microsoft's newest additions to its set of database APIs: OLE DB, which is intended to replace the older Data Access Objects (DAO) and Remote Data Objects (RDO) APIs. OLE DB provides an extremely flexible Component Object Model (COM) interface between data providers and data consumers. In Visual C++ 5.0, this flexibility can make things a bit complicated at times. However, Visual C++ 6.0 added OLE DB functionality to the MFC and ATL AppWizards, making OLE DB development quite easy.
