Cоnsider the relаtiоn schemа R(A, B, C, D, E) аnd the set F = {B → D, CD → E, E → A, A → BC} оf functional dependencies. Assume that R is decomposed into the relation schemas R1(A, B, C, E) and R2(B, D). Use the Nonadditive Join Test for Binary Decomposition to determine if this is a lossless decomposition. Further, test and explain whether it is dependency preserving.
