Solution architecture is a practice of defining and describing an architecture of a system delivered in context of a specific solution and as such it may encompass description of an entire system or only its specific parts. Definition of a solution architecture is typically led by a solutions architect. ==Definitions== There are many definitions of "solution architecture" in the industry but as of yet no official definition exists. The Open Group (2009) defined solution architecture as: :''A description of a discrete and focused business operation or activity and how IS/IT supports that operation. A Solution Architecture typically applies to a single project or project release, assisting in the translation of requirements into a solution vision, high-level business and/or IT system specifications, and a portfolio of implementation tasks.''〔The Open Group. ''Architecture Framework TOGAF™ Version 9.'' 2009. p. 93〕 Definition provided by Gartner (2013) includes a hint of a relationship between a solution architecture and the enterprise architecture: :''A solution architecture (SA) is an architectural description of a specific solution. SAs combine guidance from different enterprise architecture viewpoints (business, information and technical), as well as from the enterprise solution architecture (ESA).''〔Gartner, "(IT Glossary )," at ''gatner.com,'' 2013. Accessed 00-03-2015.〕 And Greefhorst and Proper (2013) define solution architecture as: :''An architecture of a solution, where a solution is a system that offers a coherent set of functionalities to its environment. As such, it concerns those properties of a solution that are necessary and sufficient to meet its essential requirements''〔Danny Greefhorst & Erik Proper, ''Architecture Principles: The Cornerstones of Enterprise Architecture,'' 2011. p. 25〕 Most definitions agree that the distinguishing characteristic of a solution architecture is that its context is a specific solution or deliverable as opposed to an entire enterprise or a segment of an enterprise. Furthermore, definitions put emphasis on a very specific nature of solution architecture and on its alignment with higher-level principles and specifications. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solution architecture」の詳細全文を読む スポンサード リンク
