Let us consider an imaginary university called St. Nordaf.  St. Nordaf has two faculty, two students, two courses, and three registrations of students in courses, each of which is associated with a registration record.  These objects are linked to each other: professors teach classes, students register in classes, etc.  Each of the objects in the domain has properties that we care about.
