This schema covers the basic entities needed for a Virtual Classroom Platform. Here are some explanations:

  • Users have personal information stored, including their username, password hash, email, and role (student, teacher, admin).
  • Courses are defined with details such as name, description, teacher (linked to a user), start date, and end date.
  • Classes represent individual sessions within a course, with information like the class name, schedule, and meeting link.
  • Assignments are associated with specific courses and have details like title, description, and due date.
