Entities and Attributes of Learning Management System

In the Learning Management System (LMS) database, three key entities—Course, User, and Assignment—are defined. Courses are uniquely identified by a course_id and characterized by title, description, start_date, and end_date. Users, distinguished by user_id, encompass attributes such as username, encrypted password, email, and role (e.g., student or instructor)....
