MVC (Model-View-Controller) is a software architecture pattern that enforces separation of concerns. By isolating these components development, testing and maintenance can occur independently, reducing dependencies in the code.
#Model
The model concerns itself with how the data is stored, retrieved and the business concepts that derive from the data should be interpreted.
#View
The view concerns itself with how the data is presented, formatted and interacted with.
#Controller
The controller concerns itself with the rules for how the view may change the model, what information can be accessed and what changes are allowed to be made.
