Question: Consider the relation schema R ( A , B , C , D , E , F ) with the FDs S = { A

Consider the relation schema R(A, B, C, D, E, F) with the FDs S = {A D, AC DE, B ACD, D B}. Compute a minimum cover Sc of S and explain the steps in detail.

Based on the minimum cover Sc of the previous question, determine whether the attribute set AF is a candidate key of R.
