I go the otherway and try to have a business rule in the code to handle it. Why? Because I might want to switch database engines (VFP to MS SQL or mySQL). My belief is that I will have less refactoring to do if I enforce all of the rules in the application, fewer places to look when something goes wrong. Not to be misleading, I do use RI, but the triggers refer to code.

Don,

Thanks a lot for the answer. I want to gather this information from as many users from UT as possible, so when I would be able to see what is the preferred guideline here.
