Question
Functional Dependencies
Show all the working. Do not simply write answers. If essential steps, such as edge
diagrams, transitive inferences are missing, points will be deducted.
A-1 Transitive Dependency and Keys (5 points)
You have a relation R(L,M,N,O,P,Q) and a set of functional dependencies F =
{LNO-M, MN-LOP, NO, OP-LN}.
• [2pt] Can we infer NP → LM from F?
[3pt] Can we infer NQ → LO from F?
