title: Appropriate database schema
body: <p>My database design skills are a little rusty. I've done the best I can but have no way of knowing if what I've produced is good, bad or "good enough".</p>
  
  <p>Could I please have some feedback on my design. </p>
  
  <p>To be more specific: Will this design work sufficiently?</p>
  
  <p>Database will be mySQL.</p>
  
  <p>Thanks.
  J.</p>

  <p><em>edit</em>: Some further clarification:</p>
  
  <ul>
  <li><p>A brand may have a category or it may not. </p></li>
  <li><p>The meta table can be filled out without it actually belonging to a model (in cases where the actual model is not known)</p></li>
  </ul>
