The Model-View-ViewModel pattern is similar to the Model-View-Presenter, except you have a model tailor-made for the View, called the ViewModel. The ViewModel contains all the UI-specific interfaces and properties necessary to make it easy to develop a user interface. The View binds to the ViewModel, and executes commands to request an action from it. The ViewModel, in turn, communicates with the Model, and tells it to update in response to user interaction.
