All our databases contains their own indexes based on the defined key fields. We relate records together based on the primary key fields. That way one can add/delete/modify records without disturbing any relationships. The only constraint is that the defined primary key has to be unique, but fortunately that's a characteristic of the kind of applications we do (Order Entry, Proof-of-Delivery, Inventory, etc.).
