The diagrams are 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. Some key elements in a software architectural model include:

Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
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]
Early attempts to capture and explain software architecture of a system were imprecise and disorganized, often characterized by a set of box-and-line diagrams. [26] Software architecture as a concept has its origins in the research of Edsger Dijkstra in 1968 and David Parnas in the early 1970s. These scientists emphasized that the structure of ...
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]
Overview of a three-tier application. Three-tier architecture is a client-server software architecture pattern in which the user interface (presentation), functional process logic ("business rules"), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms. [14]
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.
