Fine. This seems as good a place as any to say what I thought of after
that previous post.

This is for all those people who think "if I don't understand it, then it must be wrong" (is Tony listening :-)

Now. It's not words of one syllable, I'm afraid, but I'm trying to explain something very heavy as simply as I can.

Let's start by defining what the words mean.

LOOK at the subject of this thread again. It is an AXIOM of relational theory that data comes in tuples. Show me that that's true! And because it's an axiom, mathematics itself tells you that logic CAN not give you an answer!

Cheers,

Wol
