Lesson 23. Programming with ADO

This chapter takes a look at ActiveX Data Objects, or ADO, Microsoft's object-oriented interface to OLE DB data sources. ADO was originally conceived in version 5 to replace the Data Access Objects (DAO) and Remote Data Objects (RDO) interfaces, providing both a wider array of features and a higher degree of flexibility. In Visual C++ 6.0, direct OLE DB access has replaced ADO as the primary method of OLE DB data source access. However, there are many developers still using ADO, and many legacy Visual C++ applications that rely on ADO to access databases.
