Oops! I guess I left out an important table in my effort to simplify.
Student(studentID[pk], sName)
Catalog(courseID[pk], cName)
CourseSchedule(termNo[pk], courseID[references catalog.courseID])
Enrollment(studentID[pk, references Student.studentID], termNo[pk,
references CourseSchedule.termNo], lineNo[pk, references
CourseSchedule.lineNo])
