Consider functional dependency as to be minimal

Question

When is a functional dependency F considers as to be minimal?

Answer 1

A functional dependency F considers as being minimal:

• All dependency within F has a single attribute for its RHS (right hand side).

• This cannot replace any dependency X -->A within F along with a dependency Y--> A here Y is an appropriate subset of X and even have a set of dependency which is equivalent to F.

• We can’t eliminate any dependency from F and even have set of dependency which is equivalent to F.
