Who says that a relation is an array?

Wow. I wonder what kind of trivial or specialized applications you have in
mind. General purpose databases, of whatever flavor, are complex beasts,
no matter what. A lot has been written about databases, many solutions
have been tried, a lot of research is going on.  No use ignoring all of
it. So far I think you are just repeating the *questions* that have
accompanied the huge database efforts.
