Conservative: Evaluative security. OneData compares the privileges of the child entity with the privileges of the conceptual (root-level) object and applies the most conservative security to the child object. This security option overrides entity-level privileges if the root-level security is more conservative that of the child entity.

Entity Based: Non-evaluative security. OneData applies the security privileges as they are assigned to each object. For example, if the user-privileges in the conceptual object are read-only and edit in the child object, OneData implements the security as assigned to the entity, allowing the user to edit the child object and view the conceptual object.

Root Based: Inheritance and override security. OneData applies the security assigned to the root-level object to the child object, overriding the entity-based child-level security. For example, if a user has edit privileges for the root-level object and read only privileges for the child-level object, the user will have edit permissions for both objects. Similarly, if the user has read-only privileges on the root-level object and edit privileges for the child object, OneData overrides the edit privileges for the child object and grants the user only view privileges for both objects.
