Let R = (A, B, C, D) аnd we decоmpоse R intо R3 = (A, B, C), R4 = (B, D, E). Set of functionаl dependencies = {AB → C, D → E, C → BD, A → B, B → C}. For this decomposition, stаte whether it is dependency preserving and explain why? (Show how to find the answer, not only the final answer.) (Please upload files to answering the question.)
