A relation R (A, B, C, D, P, Z) is having two FDs F and G. Check if F = G. Demonstrate the steps involved in finding the equivalence.

Set F =

A C

AC D

P AD

P Z

Set G

A CD

P AZ (5 marks)

a.A Relation R(P,Q,R,S,T) is decomposed into

R1(P, S)

R2(P,Q)

R3(Q,T)

R4(R,S,T)

R5 (P,T)

Check whether the decomposition is lossless join decomposition. Show all the steps clearly
