An architectural model (in software) is a diagram created by using available standards in which the primary aim is to illustrate a specific set of tradeoffs inherent in the structure and design of a system or ecosystem. Software architects utilize architectural models to facilitate communication and obtain peer feedback.
Example of an IDEF0 function model. Functional Flow Block Diagram Format. [1] Decomposition structure. Static, dynamic, and requirements models for systems partition. Business Process Modeling Notation Example. Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in ...
The C4 model documents the architecture of a software system, by showing multiple points of view [5] that explain the decomposition of a system into containers and components, the relationship between these elements, and, where appropriate, the relation with its users. [3] The viewpoints are organized according to their hierarchical level: [2] [3]
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.
Examples include Circuit Breaker. [1] [2] [3] Software Architecture Style refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions. Architecture styles typically include a vocabulary of component and ...
Structured analysis and design technique (SADT) is a systems engineering and software engineering methodology for describing systems as a hierarchy of functions. SADT is a structured analysis modelling language, which uses two types of diagrams: activity models and data models.
They became a necessity in complex systems design to "understand thoroughly from exterior design the operation of the present system and the relationship of each of the parts to the whole." [3] Many specific types of functional block diagrams have emerged. For example, the functional flow block diagram is a combination of the functional block ...
An architecture description will often employ several different model kinds to effectively address a variety of audiences, the stakeholders (such as end users, system owners, software developers, system engineers, program managers) and a variety of architectural concerns (such as functionality, safety, delivery, reliability, scalability).
