Analyzing Roles and Entity Types

Use an Entity Type/Role Matrix to analyze which roles use what data, as in the following illustration.

For each role that accesses a particular entity, use one of the symbols, listed in priority order, in the following table.

Symbol	Represents	Description
C	Create	Role creates the entity.
D	Delete	Role deletes the entity.
U	Update	Role updates the entity.
R	Read only	Role requires read-only access to the entity.

If an entity type has no Create action, check which role is responsible for creating the entity.

If an entity is created by more than one role, check which role should be the owner of that entity type. Alternatively, check to see whether the entity type could be partitioned by role ownership.
