Enterprise, departments, and locations

The enterprise Palm Tree Publications has its global headquarters in the U.S. with several departments (such as editorial, engineering, marketing, website, and so on). Each department has staff in the United States, Germany, and India. As shown in following figure, the enterprise, departments, and locations form a hierarchy. In this chapter, we will build this hierarchy with a model called role-based access control (RBAC).
