초록
소프트웨어 아키텍처는 소프트웨어 시스템이 존재하기에 앞서 소프트웨어 시스템에 관한 많은 결정을 내릴 수 있게 하고 아키텍처 수준에서 시스템을 분석 가능하게 함으로써 체계적으로 계획 된 소프트웨어 개발이 가능하도록 한다. 이와 마찬가지로 아키텍처 기반의 소프트웨어 진화 계획은 소프트웨어 진화가 진행되기 이전에 아키텍처 수준에서 진화에 대한 많은 단계별 결정들을 내리고 분석하게 함으로써 체계적으로 계획된 진화가 가능하도록 한다. 본 논문은 아키텍처 기반의 결정적 진화계획에 대하여 소프트웨어 진화계획에 관련된 용어들과 개념들을 정의하고 또한 결정적 소프트웨어 진화계획들로부터 최적의 선택을 할 수 있도록 진화설계를 가치관점에서 평가하는 프레임워크를 제시함으로써 아키텍처 기반의 소프트웨어 진화 계획을 수립하는 방법론적 기반을 제공한다. 또한 본 연구의 프레임워크를 적용한 사례를 통하여 제안하는 프레임워크의 적용방법과 효용성을 보인다.
Abstract
Software architecture allows us to make many decisions about a software system and analyze it even before it exists in order to make systematic and planned development possible. Similarly, architecture-based software evolution planningmakes planned evolution possible by allowing us to make many decisions about evolution of a software system and analyze its evolution at the level of architecture design before software evolution is realized. In this paper, we develop a framework for architecture-based software evolution planning for the class of deterministic evolution plans by defining and relating various essential concepts and developing its valuationmechanism so that a plan with the greatest value among candidate plans can be selected as an optimal plan. A case study is conducted for explicating the framework and exemplifying its usage.
