John,

Could you clarify some of this discussion for those of us who've been lurking around. To use Marcus' example of 3 entities, a) Customers b) Phone Numbers & c) Invoices. Then assuming that the system specs call for a 3 tier design with a browser front-end, VFP middle and SQL on the back-end.

How would you recommend the code look for providing RI for the Phone number and Invoice entity?

Thanks,

PF
