What is view and view point?
A view is a representation of a whole system from the perspective of a related set of concerns. A view is what you see. A viewpoint is where you are looking from – the vantage point or perspective that determines what you see. Viewpoints are generic, and can be stored in libraries for re-use.
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 an architectural perspective?
An architectural perspective is a collection of activities, tactics, and guidelines that are used to ensure that a system exhibits a particular set of related quality properties that require consideration across a number of the system’s architectural views.
What is the purpose of 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.
What is view and viewpoint in software architecture?
Views are an ideal mechanism to purposefully convey information about architecture areas. In general, a view is defined as a part of an architecture description that addresses a set of related concerns and is addressed to a set of stakeholders. Viewpoints are a means to focus on particular aspects of the architecture.
How many views do we have in architecture?
When a project is still on the proverbial drawing board, architectural draftsmen work in three different primary views of a given structure, and they’re trained to know which ones to use when.
What is architectural views in software engineering?
Philippe Kruchten [Kruchten 95] describes an architecture for software intensive systems called “the 4+1 Architectural View Model”. The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers and project managers.
What are views and models?
The model is any of the logic or the database or any of the data itself. The view is simply how you lay the data out, how it is displayed. If you want a subset of some data, for example, my opinion is that is a responsibility of the model. The model knows how to make a subset.
What is perspective in design?
Perspective is a method of representing three-dimensional space on a flat surface. It depicts an idea of space that seems to coincide with our understanding of reality.
What do you mean by viewpoint in architecture?
More specifically, a viewpoint defines: how to construct and use a view (by means of an appropriate schema or template); the information that should appear in the view; the modeling techniques for expressing and analyzing the information; and a rationale for these choices (e.g., by describing the purpose and intended audience of the view).
Which is the best description of a viewpoint library?
A “viewpoint library” is a collection of the specifications of architecture viewpoints contained in the Reference Library portion of the Architecture Repository. An architecture view is what you see; an architecture viewpoint is where you are looking from – the vantage point or perspective that determines what you see
Which is the best definition of data architecture?
Data architecture is the foundation of an effective data strategy. According to data architecture definition, it is a framework of models, policies, rules and standards that an organization uses to manage data and its flow through the organization.
How are models used in the data and Information Viewpoint?
DoDAF-described Models within the Data and Information Viewpoint provide a means of portraying the operational and business information requirements and rules that are managed within and used as constraints on the organizations business activities.
