There are many different ways to connect a database (or DBMS) with C++, but database connectivity is not actually part of the C++ language itself. This aspect is handled by 3rd party data access components or classes. You specifically mentioned MS Access, so you'll want to specifically look at the Microsoft Data Access Components (MDAC), Data Access Objects (DAO), OLE DB, ActiveX Data Objects (ADO), Open Database Connectivity (ODBC), Microsoft Joint Engine Technology (JET) and Microsoft Access Engine (ACE Engine), to name but a few of the possibilities available. Consult your IDE documentation to see what's available and consult your DBMS documentation for connectivity options. With so many options, connecting to the DBMS is actually the easy part (you simply have to decide which method is most appropriate to you). But a good understanding of SQL is required to make any use of that connectivity.
