MVC VS MVP VS MVVM

MVC:

In MVC , M is a model which can hold logic to persists the data. V represents view it just responsible to display data  and C is controller .

C Is heart for the MVC. Controller is responsible to handle the incoming request and invoke the corresponding view by passing the model.

Controller can call multiple view by as per business logic .

MVP:

In MVP , P stands for presenter and Controller is replaced  by Presenter. Presenter is not responsible to handle the  input request. Presenter and View communicates with each other

thorough some interface. Presenter is responsible for handling all the requests made by the view and  Communicate with model and updates the view. In MVP , The Presenter

should associated with one View.

MVVM:

In MVVM, VM view model  is same as Presenter But VM can have multiple views. View has a reference to ViewModel and it supports two way binding.

 

 

All above design patterns are used to implement loosely coupled system which allows us achieve   extendibility, testability  and scalability .
