    Yep, that pretty well sums it up. I've been reading Hugh Darwen for a couple of days and working through Tutorial D and the Rel implementation. 6th normal form brings its own bag of headaches, and while I tend to avoid NULLs if I can help it, I'm not sure which set of headaches I'd prefer to deal with, if given an either-or choice.

    I'm a little surprised that this thread hasn't generated more traffic. It could be that everyone has already staked out their positions and they feel no need to re-defend them.

    It's because they hi-jacked a previous thead of mine. Everyone exhausted themselves there.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
