'''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.<ref name="DSA2">{{cite book |last=Clements |first=Paul |title=Documenting Software Architectures: Views and Beyond, Second Edition |author2=Felix Bachmann |author3=Len Bass |author4=David Garlan |author5=James Ivers |author6=Reed Little |author7=Paulo Merson |author8=Robert Nord |author9=Judith Stafford |publisher=Addison-Wesley |year=2010 |isbn=978-0-321-55268-6 |___location=Boston |language=en-US |author3-link=Len Bass}}</ref><ref>{{Cite web |title=Software Architecture |url=https://www.sei.cmu.edu/research-capabilities/all-work/display.cfm?customel_datapageid_4050=21328 |access-date=2018-07-23 |website=www.sei.cmu.edu |language=en-US}}</ref>
