Suppose you are given a relation R-(A,B,C,D,E) with the following functional dependencies: {BC→ADE,D→B}. a. Find all candidate keys. b. Identify the best normal form that R satisfies (1NF , 2NF , 3NF , or BCNF). c. If the relation is not in BCNF, Decompose it until it becomes BCNF, At each step identify a new relation, decompose and re-compute the keys the normal forms they satisfy.
