Hey basically I am confused between the differences of a class diagram and an ERD. I have created what I thought was an ERD but my flatmate seems to think it is a class diagram. What is it?

    You need to answer a more important question. Is your model an Object model, and ER model, or a relational model? – Walter Mitty Dec 06 '15 at 11:13

Contrary to the accepted answer, and as @xmojmr noticed as well this is NOT a UML diagram, but an Entity Relationship Diagram (ERD).

The most obvious difference is the notation of the connector ends.

  • Okay thankyou. I was just confused because each of the entities are tables in my database. I think I may have messed it up a bit and am not sure if this would even be a correct ERD. – J.Proud Dec 06 '15 at 15:20
