Students enrolling in courses is typically modelled with which cardinality ratio?

A1:1, one student to one course
B1:N, one student to many courses
CN:1, many students to one course
DM:N, many students enrol in many courses
Answer & Solution
Correct answer: D. M:N, many students enrol in many courses
Each student takes many courses in a semester, and each course has many students enrolled. That is M:N. 1:1 would mean each student takes only one course AND each course has one student 1:N or N:1 would only constrain one side. Real enrollment is two-sided many-to-many.
