Editing Software design pattern (section)

== Relationship to other topics ==
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. <ref name="O'Reilly Media">{{Cite book |title=Fundamentals of Software Architecture: An Engineering Approach |publisher=O'Reilly Media |year=2020 |isbn=978-1492043454}}</ref><ref name=":0">{{Cite book |title=Design Patterns: Elements of Reusable Object-Oriented Software |isbn=978-0201633610}}</ref><ref name=":1">{{Cite book |title=Patterns of Enterprise Application Architecture |isbn=978-0321127426}}</ref>

[[List of software architecture styles and patterns|Software Architecture Pattern]] refers to a reusable, proven solution to a recurring problem at the system level, addressing concerns related to the overall structure, component interactions, and quality attributes of the system.{{Citation needed|date=January 2025}} Software architecture patterns operate at a higher level of abstraction than 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.

[[List of software architecture styles and patterns|Software Architecture Style]] refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions.{{Citation needed|date=January 2025}} 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 [[Multitier architecture|Layered Architecture]], [[Microservices]], and [[Event-driven architecture|Event-Driven Architecture]]. <ref name="O'Reilly Media" /><ref name=":0" /><ref name=":1" />
