I guess you are first of all very confused as to what the relational model is, therefore you probably are extremely unqualified to assert with no arguments: that "the relational methods results are not satisfactory such as highly variable/complex data structures that could be thought of as graphs" .

You need to learn is that a graph is equivalent to a binary relation, and incidentally the relational model is very well suited for guess what: relations.

As to "the model used by the human brain", if you knew that, you'd be a Nobel prize winner, and you wouldn't waste your time trolling comp.database.theory :) Received on Fri May 02 2003 - 17:09:37 CDT
