" Attempting to stitch these two worlds together in a hand coded method without architecture is very common, and results in the model object being polluted with knowledge of the interface, and vice-versa. This makes the code very inflexible and difficult to maintain. For this reason (among others), many programming shops develop the user interface design early in the process of design, and freeze the interface early. The unfortunate side effect of this is that the domain of the problem often isn't clearly understood by the programmers until late in the implementation process. Thus, just at the time that the developers are finally competent to create a good interface, they are kept from changing it. MVC models allow the code to be more flexible later in the development process, allowing for changes that make sense at the time it makes sense to make them. Event driven In contrast, objects in object oriented programming are composed of methods and data members that attempt to model something from the domain of interest. Mobile Home Model The best models are fully encapsulated, meaning that they implement every aspect of that real world object of interest to the domain of interest, and that they don't have any extra code that doesn't model the real world. Encapsulation also means that the class is implemented in such a way that the internal representation of data is not exposed to the user of the object. "
