title: Design Pattern - Facade
body: <p>The Facade design pattern is centered around "Association" over inheritance, correct? </p>
  
  <p>If there is a car system like this:</p>
  
  <p>Car (class)</p>
  
  <p>-> Body (class)</p>
  
  <p>-> Steer wheel (class)</p>
  
  <p>-> Chassie (class)</p>
  
  <p>-> Wheels (class)</p>
  
  <p>Then these classes are not inherited from Car are they? Because in theory, I've been taught that inheritance has a "Can be" relationship.. "Person CAN BE a Student" ... "Car HAS A Chassie" Which would infer that it is Association?</p>
  
  <p>Any ideas? :)</p>
