Question: Suppose a relation with attributes A, B, C, D, E, and F satisfies the following FDs. C A BE F BF CD DF B Now,

Suppose a relation with attributes A, B, C, D, E, and F satisfies the following FDs. C A BE F BF CD DF B Now, compute closure for the following sets:

(i) {D, E}, (ii) {D, F}, (iii) {B, E, F}. [6 points]

Assume that there are 4 attributes A, B, C, D, and the set of FDs is S = {C B, A C}. Now, compute the closure for the FDs in S. [6 points]
