Wikipedia defines it as:</p> <p>“MVVM facilitates a clear separation of the development of the <a href="http://en.wikipedia.org/wiki/Graphical_user_interface" title="Graphical user interface">graphical user interface</a> (either as <a href="http://en.wikipedia.org/wiki/Markup_language" title="Markup language">markup language</a> or GUI code) from the development of the <a href="http://en.wikipedia.org/wiki/Business_logic" title="Business logic">business logic</a> or <a href="http://en.wikipedia.org/wiki/Back_end" title="Back end">back end</a> logic known as the model (also known as the data model to distinguish it from the view model). The view model of MVVM is a value converter, meaning that the view model is responsible for exposing the data objects from the model in such a way that those objects are easily managed and consumed”</p>
