Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the ...
The Zachman Framework of enterprise architecture. The Zachman Framework is an enterprise ontology and is a fundamental structure for enterprise architecture which provides a formal and structured way of viewing and defining an enterprise. The ontology is a two dimensional classification schema that reflects the intersection between two ...
Computer architecture. Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1]
The Department of Defense Architecture Framework (DoDAF) defines a standard way to organize a systems architecture into complementary and consistent views. It is especially suited to large systems with complex integration and interoperability challenges, and is apparently unique in its use of "operational views" detailing the external customer's operating domain in which the developing system ...
Example of a system context diagram. [ 1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [ 2] This diagram is a high level view of a system. It is similar to a block diagram .
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. The four views of the model are logical ...
An enterprise architecture framework ( EA framework) defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers, or views ...
Overview. The ISO/IEC/IEEE 42010 [ 1] document, Systems and software engineering—Architecture description, defines an architecture description language as "any form of expression for use in architecture descriptions" and specifies minimum requirements on ADLs . The enterprise modelling and engineering community have also developed ...
