Constructing a link such as second course may be done by starting with a number of connections that are many to one in nature. Does the limitation on the relation's many-to-one cardinality get enforced by both the main key constraint and the foreign key constraint? What leads you to believe that is the case?

All relations with the same LHS of the minimal FD should be grouped in one relation. e.g. A->B;A->C, ==> A->BC Give your relations an arbitrary and UNIQUE one-character name. e.g. A->B; B->C on relation S(A, B, C) decomposes into: V(A,B); P(B,C) Relations:
