What I have found in development is to put referential integrity and some
business logic in the database during development. That helps catch errors
in the program logic. Then, I usually take it out of the production system
to gain better performance.
Of course, you could leave it there for production. That is useful if you
have systems which might try to 'end run' the object design to work directly
with the db. Not that 'that' ever happens... =)
