Oracle Data Safe has expanded the discovering and defining of referential relationships in a sensitive data model to include composite relations

Referential relationships in a sensitive data model have been expanded to support composite relationships. Additionally, a custom group masking format will automatically be created and applied to any composite relationship that is defined in a masking policy, assuming it is defined in the related sensitive data model. For more information see Add or Remove a Referential Relationship from a Sensitive Data Model in the Using Oracle Data Safe guide.
