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

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

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

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

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