What we somehow need to educate these front-end developers about is that front-ends are technically incapable of enforcing referential integrity.

They give the appearance of doing so but actually do not and can not. No front-end designable is capable of keeping someone accessing the data with any other tool from destroying it be that batch loads with SQL*Loader, DBAs with SQL*Plus, or a host of tools that use ODBC or JDBC.

It is really a question of education and we need to educate them about those factors we think of as basic starting with the fact that data has value.
