What I find ignorant and stupid is the suggestion that field constraints have anything to do with the relational model, which places no restrictions on data types. If the self-aggrandizing ignorant had bothered to educate herself on the fundamentals instead of pursuing some idiotic agenda by comparing the flaws of seriously flawed products, she would realise this already.

The fact that the self-aggrandizing ignorant confused logical and physical with every word she speaks comes as no surprise. Received on Sun May 28 2006 - 04:52:58 CEST
