An architectural model (in software) contains several diagrams representing static properties or dynamic (behavioral) properties of the software under design [1] [2] [3]. The diagrams represent different viewpoints of the system and the appropriate scope of analysis.
A set of architectural design decisions: software architecture should not be considered merely a set of models or structures, but should include the decisions that lead to these particular structures, and the rationale behind them. [10] This insight has led to substantial research into software architecture knowledge management. [11]
The organization of the software and the organization of the software team will be congruent, he said. Summarizing an example in Conway's paper, Raymond wrote: If you have four groups working on a compiler, you'll get a 4-pass compiler. [4] [5] Raymond further presents Tom Cheatham's amendment of Conway's Law, stated as:
Illustration of the 4+1 Architectural View Model. 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 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.
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
Software product management (sometimes referred to as digital product management or just product management depending on the context) is the discipline of building, implementing and managing digital products, taking into account life cycle, user interface and user experience design, use cases, and user audience.
