• Assignments can be uploaded and are accessible to professors for grading.
• Professors manage courses, view student lists, and provide feedback on submitted work.

Conflict Management

1. Concurrent Access:

   • The system prevents over-enrollment by dynamically checking course capacity during enrollment actions.
   • Simultaneous course updates by multiple users are handled through database locks.

2. Role Conflicts:

   • Users with overlapping roles (e.g., a professor who is also a student) are assigned permissions dynamically, prioritizing higher-level privileges.

3. Data Validation:

   • Students cannot submit assignments for courses they are not enrolled in.
   • Professors cannot grade assignments for courses they do not manage.
