The Southern Widgets Corporation has many regions and operates many factories.

Each factory is located in a region, and each region can be home to many Southern Widgets Corporation’s factories.

Each of the factories is composed of many departments.

Each department has
many employees assigned to it, but each employee works for only one
department at one of the factories. An employee cannot work at more
than one factory at a time.
