Let's say that I have a relation with
the attributes A,B,C,D,E.
Is there a standard way to find the
candidate keys of that relation if I
am given a set of functional
dependencies for those attributes,
like A->B, BC->E, ED->A ?
I don't want the answer, I want to
know if there is a standard way to
find it.
