What are the types of architectural views?
The four views of the model are logical, development, process and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the ‘plus one’ view.
What is meant by an architectural view of a software system?
Software architecture involves the high level structure of software system abstraction, by using decomposition and composition, with architectural style and quality attributes.
What are architecture viewpoints?
An architectural view is a representation of one or more aspects of an architecture that illustrates how the architecture addresses the concerns held by one or more of its stakeholders. A viewpoint is a collection of patterns, templates, and conventions for constructing one type of view.
What are the three views of modeling?
4+1 view model of architecture The four views of the model are logical, development, process and physical view: The four views of the model are concerned with : Logical view: is concerned with the functionality that the system provides to end-users.
Is viewpoint necessary in architecture?
Viewpoints define abstractions on the set of models representing the enterprise architecture, each aimed at a particular type of stakeholder and addressing a particular set of concerns. Viewpoints can be used to view certain aspects in isolation, and to relate two or more aspects.
Why is it called the 4 1 View Model of architecture instead of 5?
It was developed in 1995 by Philippe Kruchten, formerly the Director of Process Development at Rational Software. The 4 + 1 View Model gets its name from the 4 primary views and 1 supporting view that are used to capture and communicate different aspects of the system.
What are architectural models called?
Architectural models are used by architects for a range of purposes: Ad hoc models, or sketch models, are sometimes made to study the interaction of volumes, different viewpoints, or concepts during the design process.
What do you need to know about architecture views?
In summary, then, architecture views are representations of the overall architecture in terms meaningful to stakeholders. They enable the architecture to be communicated to and understood by the stakeholders, so they can verify that the system will address their concerns. Note: The terms “concern” and “requirement” are not synonymous.
Are there views within a developing architecture group?
Within such an architecture there will very likely be views, in the true ANSI/IEEE Std 1471-2000 sense.
How is the 4 + 1 view model used in architecture?
They are used to identify architectural elements and to illustrate and validate the architecture design. They also serve as a starting point for tests of an architecture prototype. This view is also known as the use case view. The 4+1 view model is generic and is not restricted to any notation, tool or design method.
What are architectural frameworks, models, and views?
Architectural Frameworks, Models, and Views Definition: An architecture framework is an encapsulation of a minimum set of practices and requirements for artifacts that describe a system’s architecture. Models are representations of how objects in a system fit structurally in and behave as part of the system.
