Securing Accounts Based On Region
Assume that accounts are classified as belonging to one of the following regions:
- Northwestern
 - Northeastern
 - Southwestern
 - Southeastern
 
Assume the following company hierarchy exists:
- Senior Management has access to all customers
 - Northern Division Management has access to all customers in the Northwestern and Northeastern divisions.
 - Southern Division Management has access to all customers in the Southwestern and Southeastern divisions.
 - Northwestern Users have access to all customers in the Northwestern division.
 - Northeastern Users have access to all customers in the Northeastern division.
 - Southwestern Users have access to all customers in the Southwestern division.
 - Southeastern Users have access to all customers in the Southeastern division.
 
The following diagram illustrates the access groups and data access roles required to implement these requirements:
Notice the following about the above:
- There are 4 access groups because access to accounts is based on the region in which they are located (and there are 4 regions).
 - There are 7 data access roles because each component of every layer of the access hierarchy requires a separate data access role.
