You are suggesting that a symmetric n-ary structure is untyped. I disagree.

Explain to me how you think an asymmetric binary structure expresses more than the symmetric n-ary structure.

Low-level? That's a rather dumb thing to say. Set theory is a high-level abstraction of relatively modern invention as is predicate logic. Both are founded on thousands of years of advances in mathematics.
If that's all you see in RM, then fine.
Please don't try to tell me I see your fantasies in anything. That's just plain old ego-centric lunacy.

Again, what you say seems nonsensical and rather dumb. If you mean a normalized schema, then that is a direct application of set theory and the relational data model, which is itself equivalent to set theory. To characterize a direct application of something as "above and beyond" the thing is meaningless gibberish.

Before you voice such a conclusion, I suggest you should exhibit better understanding of the old thinking. Received on Tue Jun 06 2006 - 17:37:57 CEST
