The law is, in a strict sense, only about correspondence; it does not state that communication structure is the cause of system structure, merely describes the connection. Different commentators have taken various positions on the direction of causality; that technical design causes the organization to restructure to fit, [ 10 ] that the ...
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and 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 system.
A business analyst, domain expert, and/or enterprise architecture team will develop the organization's service model first by defining the top level business functions. Once the business functions are defined, they are further partitioned and refined into services that represent the processes and activities needed to manage the assets of the ...
In communications systems, for example, little development of solutions that use truly static bindings to talk to other equipment in the network has taken place. By embracing a SOA approach, such systems can position themselves to stress the importance of well-defined, highly inter-operable interfaces.
Business systems planning (BSP) is a method of analyzing, defining and designing the information architecture of organizations. It was introduced by IBM for internal use only in 1981, [ 1 ] although initial work on BSP began during the early 1970s.
Data Delivery Systems (Software, Hardware, Communications) support the data architecture. The hierarchy in the model is based on the notion that an organization operates a number of business functions, each function requires information from a number of source, and each of these sources may operate one or more operation systems, which in turn ...
Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for interpreting the system's properties. These styles represent the most coarse-grained level of system organization. Examples include Layered Architecture, Microservices, and Event-Driven Architecture. [1] [2] [3]
The original 1987 "Information Systems Architecture Framework". Simple example of the 1992 Framework. In the 1987 article "A Framework for Information Systems Architecture" [15] Zachman noted that the term "architecture" was used loosely by information systems professionals, and meant different things to planners, designers, programmers ...
