When is a functional dependency F said to be minimal?
Answer:
> Every dependency in F has a single attribute for its right-hand side.
> We cannot replace any dependency X A in F-> with a dependency Y A where Y-> is a proper subset of X and still have a set of dependency that is equivalent to F.
> We cannot remove any dependency from F and still have set of dependency that is equivalent to F.
