When I did the first homework in question 23 I tried to make a relationship between the policy entity and the Accident Entity. That relationship will be called covers. I remembered in the third video that you mentioned we are not allowed to use any relationship in our ER Diagram. I just wanted to make sure of that and the know whether I'll be allowed to use a relationship or not.

Thank you
