Hi Ilya, We're probably straying off-topic here, but I thought I'd just say a word or two about why you might want data checking at the DBMS level. The benefit of letting the DBMS decide what is and isn't good data is that you can then change the application on the front of the database easily (or write a new one), knowing that the rules for what data can be used and how it can be accessed are maintained at the database level (and don't need to be ported from application to application). Although I'm all for checking at the application level too -- you can never be over careful!
