DB Schema Details

Table 1: users
All the users including superadmin, admin, employee.

Table 2: courses
All the courses designed by a user (admin). Hence user_id in courses will refer to id in users.

Table 3: viewed_courses (join table between users and courses)
This table is a result of many-to-many relationship between users and courses. If the user U has viewed course C, we insert U & C as a composite primary key in viewed_courses. If U has completed C, we mark is_completed to be true. We get to know the course completion status by completed_duration attribute in the table.
