Here is unorthodox = view. I queried=20 Mathworld for "Relation" and fidn't find any. Hence the conclusion: = "There is no=20 Relation in math!"

No, the relational model is based on = the notion=20 of relation in symbolic logic. The interpretation of a relation = may be=20 required to be 1st order function free, resulting in a 1NF model; but = there is=20 no requirement that relations be 1NF for a database to be relational; = and=20 there has been a great deal of relational database theory developed = around=20 non-1NF (that is non first order function free) models. I = simply=20 gave a single reference to a single article. There are many=20 books...

This is supposed to be a theoretical = news list=20 but it seems to me that the relational bigots are incredibly ignorant = of=20 relational theory.
