Where do models in MVC contain application logic?
What people tend to call “models” are actually domain object (I blame Rails for this mass-stupidity). The application logic (interaction between domain logic structures and storage abstraction) should be a part of model layer. To be more precise: it should be inside the Services.
Which is the controller or the model in MVC?
