Consider two boys who were taught how to hammer a nail into a piece of wood. One boy might explore other ways to hammer nails such as using a screwdriver, a pencil, his bare hands, a bag of cottons etc. The other will cling to his hammer and study various ways of using different hammers, or nails depending on the wood at hand, apply varying forces when hitting the nail, etc. (and yeah, maybe even write a book about it at some point, to show the other that driving nails into wood, really should be done with the help of a hammer). :-) -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Toon Koppelaars RuleGen BV +31-615907269 toon_at_rulegen_dot_com www_dot_rulegen_dot_com Author: "Applied Mathematics for Database Professionals"
