Differences between a conceptual UML class diagram and an ERD?

Question

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

Answer 1

The ER diagrams I've seen (most frequently ERWin IE notation) have focused on the design for a database. They are concerned with primary keys, foreign keys, have unnamed relationships, and usually have no generalization / specialization.

A good UML conceptual class diagram, on the other hand, is not concerned with keys, reflects the problem domain, and has association-end properties that at least hint at the semantics of why things are related. This helps communicate the domain down to more junior developers so they don't have to guess.
