All about Model View ViewModel (MVVM) ? – Points to Note

* Its an architectural pattern used in software engineering that originated from Microsoft
* targeted at modern UI development platforms (WPF and SL)
* View-Model is responsible for exposing the data objects from the Model in such a way that those objects are easily managed and consumed. In this respect, the View-Model is more Model than View, and handles most if not all of the View’s display logic 
* Pattern is designed to support WPF and Silverlight

Elements of the MVVM pattern include:
   (1) Model as in the classic MVC pattern, the model refers to the data access layer representing the real state content.
   (2) View as in the classic MVC pattern, the view refers to all elements displayed by the GUI such as buttons, windows, graphics, and other controls.

   (3) ViewModel: the ViewModel is a “Model of the View” meaning it is an abstraction of the View that also serves in data binding between the View and the Model. It could be seen as a specialized aspect of what would be a Controller (in the MVC pattern) that acts as a data binder/converter that changes Model information into View information and passes commands from the View into the Model. The ViewModel exposes public properties, commands, and abstractions. The ViewModel has been likened to a conceptual state of the data as opposed to the real state of the data in the Model.
