• VIEW: A View define the structure and appearance of what the user sees on the screen. It binds to the view-model by only using data binding.
• Model: Model is used for data communication.
• View Model:  The ViewModel can be thought of as an abstraction of the View. It provides enough information about the Model data points that the View can use for data-binding. It contains Commands the View can use to interact with the Model. The ViewModel has a reference to the Model.
