title: Models without database access in symfony2
body: <p>I am currently learning how to use the <a href="http://symfony.com/" rel="noreferrer">symfony2</a> framework.</p>
  
  <p>Going through the <a href="http://symfony.com/doc/current/cookbook/index.html" rel="noreferrer">cook book</a>, I am starting to have a basic understanding of how everything fits together.</p>
  
  <p>However, I have 2 questions regarding Entities, which I believe are models in the MVC pattern:</p>
  
  <ul>
  <li><p>In the documentation, there seems to be a lot of talk about entities using doctrine as ORM. If I have an entity/model that does not require any ORM, is this still considered an "entity"?</p></li>
  <li><p>In most tutorials I have seen, entities are often all thrown into a folder called "entities" under the application bundle. With many entities in an application, I feel that this can become quite messy and unorganized. How can I group and organize entities?</p></li>
  </ul>
  
  <p>Cheers :)</p>
