Question 3. Suppose we have a relation R = (A, B,C, D, E , F) with a set of function ependencies F = {A → DE, AC → B, B → D}. This relation is not in Boyce-Codd Nor orm. Using one of the provided functional dependencies as a starting point, rovide a lossless decomposition of R into a set of relations {R1, ..., Rn} Such that esulting relations are all in BCNF. Show your work, explaining exactly how each
