Question: Consider the relation scheme R1 = {A, B, C, D, E, F, G, H, I} and the set of functional dependencies for the relation R1

Consider the relation scheme R1 = {A, B, C, D, E, F, G, H, I} and the set of functional dependencies for the relation R1 are

F1 = {AB C, A DE, B F, F GH, D I}.

a) Find all candidate keys of F1. Prove that these are the only keys. b) Decompose R1 into possible 3NF relations.

Note: (Please read the question carefully as the statement is similar to another question but asks different things)
