Why Mvc Architecture?

Model View Controller (MVC) architecture is a programming design paradigm, according to which different parts of a user interface-based program which be kept, broadly speaking, distinct from one another, rather than jumbled all together.
According to this concept, the Model part represents the underlying data. The View part represents the user interface which the user sees and interacts with. The Controller part mediates between the View and the Model as necessary.

The idea behind MVC is that programs should be easier to develop, debug and maintain if responsibilities for different parts of the software are distributed among different objects.
