Howdy!

...and the controversy over NULL in 1NF depends on what you mean when you say NULL. If NULL means "this datum is presently undefined", that's one thing (and not necessarily a violation of 1NF). If, on the other hand, it means "this datum does not exist in this tuple" (as in the classic repeating group situation), it's symptomatic of the the basic issue with 1NF.

But I digress...
