Architecture View
Formal
Architecture views are representations of the overall architecture that are meaningful to one or more stakeholders in the system. The architect develops a set of views that will enable the architecture to be communicated to all the stakeholders.
Practical
A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture.
