What is MVVC?

MVVM (Model-View-ViewModel) is a software architectural pattern that facilitates the separation of the development of the graphical user interface (the View) from the development of the business logic or back-end logic (the Model) through the ViewModel. The ViewModel is a value converter, meaning it is responsible for exposing (converting) the data objects from the Model in such a way that objects are easily managed and presented in the View. The View is responsible for displaying the data, and for sending commands to the ViewModel to execute.
