Simple answer plz.

Consider the following set F of functional dependencies on the relation schema r (A, B, C, D, E, F): A rightarrow BCD BC rightarrow DE B rightarrow D D rightarrow A a. Compute B^+. b. Prove (using Armstrong's axioms) that AF is a superkey. c. Compute a canonical cover for the above set of functional dependencies F; give each step of your derivation with an explanation. d. Give a 3NF decomposition of r based on the canonical cover. e. Give a BCNF decomposition of r using the original set of functional dependencies. f. Can you get the same BCNF decomposition of r as above, using the canonical cover
