(Solved) : Given Relation R Following Functional Dependencies Answer Following Questions R B C D E F Q28780517 . . .

Given the relation R and the following functional dependencies,answer the following questions. R(A, B, C, D, E, F, G) Allattributes contain only atomic values.

FD1: AB ? C FD2: BC ? E FD3: B ? D FD4: F ? G

(a) Compute A+, the attribute closure of attribute A.

(b) List the candidate keys of R.

(c) What’s the highest normal form that R satisfies and why?

(d) If R is not already at least in 3NF, then normalize R into3NF and show the resulting relation(s) and their candidate keys.Your decomposition should be both join-lossless anddependency-preserving. If R is already in 3NF, just list thecandidate keys of R.

(e) Is your answer to (d) also in BCNF? Why or why not?
