The view models is a method to describe the architecture from different views. According to this model, you can describe the architecture in these perspectives, to gain a quite good completeness of documentation.
However, this is not a 100% must. More often is that architecture is described with fewer views. Maybe only one view.
The methodology also help the designer to *think* of what he or she designs. To separate the concerns on what being described.
Viewpoints and Perspectives
4+1 View Models is very close to the concept of Perspectives and Viewpoints. But not to confuse with it. In this concept, a view is an instance from a viewpoint. A Perspective is a set of views from possibly several viewpoints. A perspective might be “Security” or “Avaiability”. https://www.viewpoints-and-perspectives.info/<< Back to list all models
