title: CRUD in a use-case diagram?
body: <p>My question is quite simple. What is the best way to bring <a href="http://en.wikipedia.org/wiki/Create,_read,_update_and_delete" rel="noreferrer">CRUD</a> into a use-case diagram? It should be <a href="http://en.wikipedia.org/wiki/Don%27t_repeat_yourself" rel="noreferrer">DRY</a>. I know, UML is sometimes discretionary, but what do you think about it?</p>
  <p>Some ideas:</p>
  <h1>1 use-case diagram</h1>
  <p><img src="https://i.stack.imgur.com/Pl45J.png" alt="usecase1" /></p>
  <ul>
  <li>Not really DRY, if there are a few CRUD objects.</li>
  </ul>
  <h1>2 use-case diagram</h1>
  <p><img src="https://i.stack.imgur.com/gQ4h7.png" alt="usecase2" /></p>
  <ul>
  <li>Not really DRY, if there are a few CRUD objects.</li>
  </ul>
  <h1>3 use-case diagram</h1>

  <ul>
  <li>I prefer this.</li>
  </ul>

  <ul>
  <li>Note maybe needless, when it is described in the documentation?</li>
