A binary relationship that is one-to-many in an ERD is best represented by adding the primary key attribute (or attributes) of the entity on the one side of the relationship as .a O a foreign key in the relation that is on the many side of the relationship the creation of a separate relation; the primary key of this new relation is a composite key b O consisting of the primary key for each of the two entities in the relationship creating a relation with a composite primary key and nonkey attributes .c O adding the primary key attribute (or attributes) of the entity on the many side of the relationship .d O as a foreign key in the relation that is on the one side of the relationship
