Draw an EER diagram that captures the "is-a" hierarchy of students in another simple database. The database captures both the "basic" information (say, student ID and student name) and "additional" information about undergraduate students. A student may enrol in the BCSc degree program, the co-op program, or both (e.g., a BCSc student is-a student).
