When is a functional dependency F said to be minimal?
Ø Every dependency in F has a single attribute for its right hand side.Ø 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.Ø We cannot remove any dependency from F and still have set of dependency that is equivalent to F.
