No, we would have to add extra column every time when we have one more variable in the polynomial.

Actually, I figured out what to do with monomials already. I'm coding it as an integer:

But then, what do I do next? Assign a surrogate key to each monomial? Certainly a goofy idea... Received on Sun Aug 31 2003 - 06:14:50 CEST
