Users are the people who access the VNNOX system.

• • • Functionality permissions: Assigning one or more roles to a user can limit the user to the corresponding permissions of the assigned role(s).
    • Data permissions: Specifying a workgroup for a user allows the user to modify and delete the data in the workgroup and its sub-workgroups only, and only to view and use the data shared from other workgroups.

The relationship between permissions, roles, users, and workgroups is shown in Figure 1.
