title: Differences between a conceptual UML class diagram and an ERD?
body: <p>If I create a conceptual class diagram such that each class captures 'name' and 'attributes' but not 'operations', have I not basically created what would be otherwise considered an ERD?  I'm trying to gain an understanding of what the differences are between creating a conceptual class diagram as I have described versus calling it a ERD?  If these are still two different animals, can somebody please explain what the differences are? </p>
