title: Controller belongs to the Presentation layer?
body: <p>I heard that controller belongs to the presentation layer. How is it possible?</p>
  
  <p>I thought that :</p>
  
  <ul>
  <li>view is for presentation</li>
  <li>model is for business logic</li>
  <li>controller is for controlling logic</li>
  </ul>
  
  <p>Is there good link to prove that controller belongs to the presentation layer?</p>
  
  <p>"Spring MVC is used for presentation layer": how can we use MVC only in the presentation layer?</p>
