Question: Consider a relation schema R (A, B, C, D) and FDs the set F:

F ={

A→B

A→C

C→D

}

a. Find the candidate keys of R.

b. Determine the highest normal form (no NF, 1NF, 2NF, 3NF, BCNF) that R satisfies. Explain your answer.

c. Decompose R so that the decomposition satisfies the next higher normal form than the one R itself satisfies.

d. Show the canonical and minimal covers of functional dependencies for the decomposed relation schemas.

e. List the candidate keys of the decomposed relation schemas.

f. Prove that the decomposition is a lossless-join decomposition and/or dependency preserving.
