Re: Quick Poll - How do you enforce referential integrty?

In new development I always use the constraints from DB2, I also added Relational Integrity to a lot of old systems (after some clean-up). 

It drives crazy the oldies (the ones that belive they know everything).

Say you have an Order Header/Order Detail relationship. You're writing
an application that deletes the Order Header record. How does your shop
handle referential integrity?

1. We do it programmatically-- our application looks in the Order
Detail file and makes sure there are no corresponding Order Detail 
records.
2. Our shop standards require we create constraints through DB2/400.
3. We don't bother checking. We just delete the Order Header record. 
Thanks
