What is MVP module?
Overview. MVP is a user interface architectural pattern engineered to facilitate automated unit testing and improve the separation of concerns in presentation logic: The model is an interface defining the data to be displayed or otherwise acted upon in the user interface.
What is MVVM pattern?
Model — View — ViewModel (MVVM) is the industry-recognized software architecture pattern that overcomes all drawbacks of MVP and MVC design patterns. MVVM suggests separating the data presentation logic(Views or UI) from the core business logic part of the application.
How does Model View Presenter work?
Data (model) and UI (view), only communicate with one another through an intermediary (the presenter) . The presenter contains the bulk of the business logic, while the view focuses on how to display the data. The controller responsibility is now split between the view and presenter.

What is the difference between MVVM and presentation model?
MVVM is a variation of Martin Fowler’s Presentation Model design pattern. MVVM abstracts a view’s state and behavior in the same way, but a Presentation Model abstracts a view (creates a view model) in a manner not dependent on a specific user-interface platform.
