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. [1] [2] [3]
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]
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.
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 ]
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 ...
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. The diagrams are created by using available standards in which the primary aim ...
Software design patterns offer finer granularity compared to software architecture patterns and software architecture styles, as design patterns focus on solving detailed, low-level design problems within individual components or subsystems. Examples include Singleton, Factory Method, and Observer. [35] [36] [37]
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.
