Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. [1][2] The architecture of a software system is a metaphor, analogous to the ...
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 ...
The C4 model is a lean graphical notation technique for modeling the architecture of software systems. [1][2] It is based on a structural decomposition (a hierarchical tree structure) of a system into containers and components and relies on existing modelling techniques such as Unified Modeling Language (UML) or entity–relationship diagrams ...
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 ...
The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. [2] In 1997, UML was adopted as a standard by the Object Management Group (OMG) and has been ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Software architectural model. 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 ...
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 ...
