You don't need to call them Model, but you could</p></li> <li><p>create a set of classes in charge of running the role of Controllers: wire somehow dependencies to view and model classes via dependency injection if possible. example: <a href="https://github.com/admiyo/CppInject" rel="noreferrer">CppInject</a>. In any case, controller classes can know both about model and view classes, so the important part is this: <strong>all the coupling between view and model objects is isolated to the controllers</strong>. </p></li> <li><p>Also, this implies, that all imperative-style programming should be confined to the controller classes as well: view and model should be declarative-style. That means, they should <strong>offer services related to its role, but avoid direct interaction with other objects as side-effects</strong></p></li> <li><p>It is not true you need to implement communication between controllers and the other components with event-style system, although such system is definitely helpful, but certainly not required</p></li> <li><p><em>surprise!</em> the above applies to any language or framework, except of course languages that somehow already force MVC down your throat from the start, i.e: ruby on rails</p></li> </ul>
