functional relations and dependencies Explanation: http://tiny.pl/lnkq -------------------------------------------------- Note added at   1 godz. (2008-02-21 21:56:08 GMT) -------------------------------------------------- Functional dependencies are determined by the semantics of the relation, in general, they cannot be determined by inspection of an instance of the relation. That is, a functional dependency is a constraint and not a property derived from a relation. Required skill: * Be able to determine all functional dependencies of a relation. * Be able to determine all candidate keys. http://tiny.pl/lnkm http://tiny.pl/lnkg With this information functional relations and dependencies in sentences are recog- nised. The main aim is to represent the most important elements and their func- tions in a normalised, simplied structure http://tiny.pl/lnkt -------------------------------------------------- Note added at   1 godz.
