normalisation
Suppose you are given a relation R with four attributes ABCD. For each of the following sets of FDs, assuming those are the only dependencies that hold for R, do the following: If R is not in BCNF, decompose it into a set of BCNF relations that preserve the dependencies. AB → C, AB → D, C → A, D → B
