For example in my membership data base my main table is RegisterOfMbrs with a PRIMARY KEY of MbrNumber. I have another table MbrCurHomeAdr PRIMARY KEY MbrNumber but MbrCurHomeAdr is related to RegisterOfMbrs and I define a FOREIGN KEY for MbrCurHomeAdr using the MbrNumber that references MbrNumber in RegisterOfMbrs. This insures that I always have a valid MbrNumber in my MbrCurHomeAdr record and That I cannot delete records from RegisterOFMbrs if a record still exists in MbrCurHomeAdr.
