Hi Ben
It matters if students can't decode the relationships because an unexpected
notation is used. I'm just researching ERD notations and have found these
so far:
- Chen
- IDEF1X
- Cachman
- Martin / IE / Crow’s foot
- Min-Max/ISO
- UML
The exam had better stick rigidly to the notation in the sample questions!
