It's because with the richness of meta-data offered by a Physical Data Model. The Actual physical data design also allows in visualizing database framework by replicating database column keys, constraints, indexes, triggers, and other RDBMS options.
Association: Associations are depicted using a dotted line and link a text or artifact to an exercise, gateway or event.

Sensible data versions They are considerably less abstract and provide better depth with regard to the concepts and interactions inside the domain into consideration. Amongst several official data modeling notation units is adopted.
