2. a) For relation R=(L,M,N,O,P) the following dependencies hold: FD={MO,NOP,PLandLMN} R is decomposed into Rl=(L,M,N,P) and R2=(M,O). Prove that the decomposition is lossless and not dependency preserving. b) Compare among super key, candidate key and primary key. 5 Let R=(A,B,C,D,E,F) be a relation scheme with the following dependenciesFD={CF,EA,ECD,AB}. Find the candidate key from the above functional dependencies
