title: How to read ternary relationship in ORM(Object role modeling) diagram?
body: <p>I have an example of allocation <code>Result</code> below. I know how to read binary relationships but this triple box marked red in the image confuses me. </p>
  
  <p>When and in what order do we read those roles after slashes inside the box : in, award of?</p>
  
  <p>I assume that we can read this diagram in 3 ways:</p>
  
  <ul>
  <li><strong>First box</strong> Student has result of Grade for Unit.</li>
  <li><strong>Second box</strong> Grade givent to Student in Unit</li>
  <li><strong>Third box</strong> Unit grants to Student award of Grade (<strong>?</strong> this one has no sense <strong>?</strong>)</li>
  </ul>
  
  <p>Can we read it any more ways?</p>
