Editing Entity–relationship model (section)

===Role naming===
It has also become prevalent to name roles with phrases such as ''is the owner of'' and ''is owned by''. Correct nouns in this case are ''owner'' and ''possession''. Thus, ''person plays the role of owner'' and ''car plays the role of possession'' rather than ''person plays the role of'', ''is the owner of'', etc.

Using nouns has direct benefit when generating physical implementations from semantic models. When a ''person'' has two relationships with ''car'' it is possible to generate names such as ''owner_person'' and ''driver_person'', which are immediately meaningful.<ref>{{Cite web|url=http://pangrammaticon.blogspot.com/2013/01/emotion-and-society.html|title=The Pangrammaticon: Emotion and Society|date=January 3, 2013}}</ref>
