Software architects utilize architectural models to facilitate communication and obtain peer feedback. Some key elements in a software architectural model include: Rich: For the viewpoint in question, there should be sufficient information to describe the area in detail. The information should not be lacking or vague.
The phenomenon of software architecture erosion was initially brought to light in 1992 by Perry and Wolf alongside their definition of software architecture. [2] Software architecture erosion may occur in each stage of the software development life cycle and has varying impacts on the development speed and the cost of maintenance.
Software architecture patterns operate at a higher level of abstraction than software design patterns, solving broader system-level challenges. While these patterns typically affect system-level concerns, the distinction between architectural patterns and architectural styles can sometimes be blurry. Examples include Circuit Breaker.

In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code .
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.
The software engineering community uses an architecture description language as a computer language to create a description of a software architecture. In the case of a so-called technical architecture , the architecture must be communicated to software developers; a functional architecture is communicated to various stakeholders and users.
Software architecture pattern is a reusable, proven solution to a specific, recurring problem focused on architectural design challenges, which can be applied within various architectural styles. [ 1 ]
