Role Definitions and Role Assignments allow you to:
List, create, edit, and delete roles in the base database.
Assign roles to users from the user, role, or design part view.
Role definitions are not constrained to a specific product but can be used throughout the base database.
Each role assignment must consist of an existing user, role, and design part.
