Question: Consider the relation R(A,B,C,D,E) and the set of functional dependencies F = {A-> B, BC -> E, ED -> A} Why are certain functional

Consider the relation R(A,B,C,D,E) and the set of functional dependencies F = {A-> B, BC -> E, ED -> A} Why

Consider the relation R(A,B,C,D,E) and the set of functional dependencies F = {A-> B, BC -> E, ED -> A} Why are certain functional dependencies called trivial functional dependencies? Give examples using the above. List all of the candidate keys for R. Is R in third normal form (3NF)? Write yes or no and give a brief reason. Is R in Boyce-Codd normal form (BCNF)? Write yes or no and give a brief reason.
