Hi:



I know the basic theory behine find F+ given a set of FD, but using
armstrong's axioms on a set of FD can take quite a long time with 6
attributes, is there any program out there that can do this kind of
stuff for us?  ie:  find F+ given a set of predefined FD over a
schema?



Thanks


Herman
