3:09 you said factory can have 0 employees but it must have a manager, how can that happen if a manager is also an employee? I think there should also be double line between employee and works_at

That’s confusing. Doesn’t a faculty have many departments, and a department can have only one faculty?
@rachelfadler
@rachelfadler Жыл бұрын
Think of a university/school setting where a department has many faculty/teachers working in there, and a faculty member usually is associated with 1 main department. Example a Computer Science department has many faculty.
