Suppose that we are given a relation schema R with four attributes, ABCD, and the set of FDs

F = (AC -> B, AD -> C, B - D ).

Assuming those are the only dependencies that hold for R, answer the following questions:

1. Is R in 3rd normal form (3NF)?

2. Is R in Boyce-Codd normal form (BCNF)?

3. Is the decomposition d = {ABD, ABC | of R a lossless-join decomposition?
