they are.

mvc vague pattern.

my view on mvc :

controller

object has collection of models , has methods viewing , editing models. talks models , returns instances of views models applied on them.

view

has definition of model attached , set of functionality display specific model.

model

encapsulates data. has methods returning state , changing state.

//controller import views  class controller   private models  //view import model  class view  //model class model

a model doesn't need know view / controller. view needs know definition of model. controller needs own models , needs know definitions of views.

you can couple them more tightly, optional.
