Relational is the _right_ model because 'it works'. It's the only truly comprehensive data model and subject of decades of research. All other data models have been found to be flawed and (nearly) discarded. If you don't care for mathematical principles, there's always ad-hoc database models. Check out Pick, OO and XML databases. They're interested in what works and ignore elegance and mathematical principles. -- Lee Fesperman, FirstSQL, Inc.
