The four types of binary relationships are one-to-one, one-to-many, many-to-one, and many-to-many. One-to-one relationships link one entity in a set to one entity in another set. One-to-many connects one entity to multiple entities in another set. Many-to-one is the reverse of one-to-many, linking multiple entities in one set to one in another. Many-to-many relationships connect multiple entities in both sets.
