Table T1(A, B, C, D, E) functional dependencies: A -> B AC -> DE D -> C List candidate key(s), and how you found the key(s). Which functional dependency causes BCNF violation? Decompose T1 into BCNF tables. Please show all work here.
Consider the following definition of equivalent sets of functional dependencies on a relation: “Two sets of functional dependencies F and F’ on a relation R are equivalent if all FD’s in F’ follow from the ones in F, and all the FD’s in F follow from the ones in F’.” Given a relation R(A, B, C) with the following sets of functional dependencies: F1 = {A B, B C}, F2 = {A B, A C}, and...
