Given the relation 

R(L,M,N,O,P)

and the FDs are;-

L->MN,P->L,NO->P,M->O

pls tell me whether i am correct or not?

the candidate keys in the above relation are- P,L,MN,NO  right?

bcoz candidate means we cant drop any attribute, it doesn't means that we should have least no. of attributes!

If a relation is decomposed into more than two relations then what is the correct method to check whether the decomposition is lossless or not? Can we use R1⋂R2→R1 or R1⋂R2→R2 pairwise for the decomposition or is there any other method?
