(Solved) : 3 Information Preservation 1 Point Suppose Given Relation R B C D Functional Dependencies Q44074891 . . .
3: Information preservation (1 point) Suppose you are given a relation R(A,B,C,D) with functional dependencies B+C and DA. State whether the decomposition of R to Si(B,C) and S2(A,D) is lossless or dependency preserving and briefly explain why or why not.
