title: How to organise Realm Storage structure in the right way
body: <p>My question concerns the basic principles of creating Realm Storage.  </p>
  
  <p>Let's assume I'm creating hackneyed DB which contains <strong>articles</strong> and <strong>authors</strong>. </p>
  
  <p>If I used SQLite engine, I'd do normalisation and create schema with 2 table: Articles and Authors with primary key <code>author_id</code> in the secon table. Please see </p>

  <p>On the other hand, I guess that sticking to Document-Oriented DB approach, I should make tree-like structure. Please see </p>

  <ul>
  <li>The question is what approach should I take and why?  </li>
  <li>Will the storage size grow exponentially in the second case and what approach is more judicious in terms of performance?</li>
  </ul>
  
  <p>Answer from the Realm team would be really appreciated.</p>
