Consider the relation R- IA, B, C, D, E, Fl and the following set of FDs on R: Consider also the relations: R1 (A, B, C), R2 (A, B, C, E, F), and R3 (A, B, C, D). Q3.1 (2x3-6 points) Compute the projection of the FD-set F on each of the three Q3.2 (2x3-6 points) What are all the candidate keys (i.e. the keys) for each of the Q3.3 (1x3-3 points) For each of the three relations, indicate if it is (A) BCNF and (B) Q3.4 (6 points) Is it possible to decompose each R2 and R3 into new schemas such relations R1, R2 and R3. Only write down a minimal cover three relations R1, R2 and R3? 3NF. Explain your answer. preserving? Show your work.
