Keep in mind that VFP is both, a programming language and a DBMS.

You can use VFP as a programming language and Oracle or DB2 as the DBMS if your company's requirement require a stronger DBMS than what VFP provides. Using VFP in this scenario is incredible powerful since VFP has a data engine built-in that can be use to process records downloaded from Oracle or DB2.
