Hi Ben<br><br>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:<br>
<ul><li>Chen</li><li>IDEF1X</li><li>Cachman</li><li>Martin / IE / Crow’s foot</li><li>Min-Max/ISO</li><li>UML</li></ul>The exam had better stick rigidly to the notation in the sample questions!<br><br><br><div class="gmail_quote">
