title: Recommendation for a good entity relationship diagram building tool for occasional usage?
body: <p>Freeware is a plus. Could you also describe with one sentence why it should be good enough for occasional usage?</p>
  
  <p>Edit: You might check this cool <a href="http://www.reference.com/browse/entity-relationship+diagram" rel="noreferrer">link</a> , providing more info about entity relationship diagrams and tools</p>
  
  <p>Edit: For the chosen answer couple of tips
   - click on entity even it looks like circle and type the name and Enter - it will give you the Entity box
   - Click on association , Ctrl + L would give you the nice line </p>
