Tiny College uses a Student Registration System to manage course enrollment, class schedules, and student records. The database structure includes the following tables: COURSE, CLASS, ENROLL, and STUDENT.$$

Consider this scenario: Sarah, a student at Tiny College, wants to enroll in a new set of classes for the semester. She logs in to the registration system and selects courses based on her department's requirements. Each course has one or more class sections with specific times, rooms, and instructors. For example, Sarah might enroll in a "Database Systems" course, choosing a section taught by Professor Smith on Tuesdays and Thursdays.$$

Once Sarah selects her classes, the system updates the ENROLL table to reflect her enrollment and assigns her a grade placeholder for each class. The system also maintains her student information, including her program, GPA, and contact details.
