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.
The view model is an abstraction of the view exposing public properties and commands. Instead of the controller of the MVC pattern, or the presenter of the MVP pattern, MVVM has a binder, which automates communication between the view and its bound properties in the view model. The view model has been described as a state of the data in the ...
Illustration of the 4+1 Architectural View Model. 4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
A view model is a framework that defines the set of views or approaches used in systems analysis, systems design, or the construction of an enterprise architecture. Since the early 1990s, there have been a number of efforts to define standard approaches for describing and analyzing system architectures.
The C4 model was created by the software architect Simon Brown between 2006 and 2011 on the roots of Unified Modelling Language (UML) and the 4+1 architectural view model. The launch of an official website under a Creative Commons license [3] and an article [4] published in 2018 popularised the emerging technique. [1]
Architectural Model contains a definition of an architectural model from the University of Ottawa's Object Oriented Software Engineering database. Architectural Tradeoff Analysis Method (ATAM) is a method by which architecture can be evaluated for suitability and fit to requirements.
DoDAF view model shows the linkages among views. [2] The DoDAF defines a set of products that act as mechanisms for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through graphic, tabular, or textual means. These products are organized under four views: Overarching All View (AV),
It is further widely used in classical systems engineering to show the order of execution of system functions. [7] One of the earliest pioneering works in information systems modeling [8] has been done by Young and Kent (1958), who argued:
