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 ...
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 ...
High-level design (HLD) explains the architecture that would be used to develop a system. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces. The HLD can use non-technical to mildly technical terms which should be understandable to 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 ...
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 .
The Java Platform, Enterprise Edition architecture is a layered reference architecture which provides a template solution for many enterprise systems developed in Java. Examples of implementing frameworks include Glassfish and Wildfly. The IBM Insurance Application Architecture [3] is a reference architecture for the Insurance domain.
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 ...
