• 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.
