Abstract

Systematic modeling methods. which can correctly represent user requirements, are absolutely required to extract components when developing components. But, components are designed and developed In general based on the concept of object modeling so that they lacks in supporting representing cooperation and interaction as well as reuse. It means extracting components is not easy to be applied to complicated and sophisticated large-scale systems. This paper utilizes a role modeling method based on the role of objects, not on objects themselves, to complement object modeling. The Role modeling can break down a complicated system into simple models through abstracting the pattern of objects based on roles of the objects. In this study, an UML-based method extracting components through role modeling is embodied. UML can represent models from various standpoints so that role models arc also viewed from several points of view.

컴포넌트 소프트웨어 개발에서 양질의 컴포넌트를 추출하기 위해서는 사용자의 요구사항을 정확하게 표현할 수 있는 체계적인 모델링 방법이 필요하다. 피러나 컴포넌트는 일반적으로 객체 모델링을 기반으로 설계되고 개발되기 때문에 상호작용과 협력의 표현, 상속으로 인한 재사용 문제 등을 해결하는데는 한계가 있으며 복잡한 구조를 가진 대규모 시스템에서 컴포넌트를 추출하기에는 용이하지 않다. 따라서 객체 모델링을 보완하기 위하여 객체 중심이 아닌 객체의 역할을 중심으로 하는 역할 모델링 기법을 활용할 필요가 있다. 역할 모델링은 대체들의 패턴을 추상화하고 복잡한 대규모 시스템을 관계의 분리를 통하여 간단한 모델로 생성할 수 있도록 객체의 역할을 중심으로 모델링하는 기법이다. 본 논문은 UWL 기반에서 역할 모델링을 통하여 컴포넌트를 추출하는 방법을 연구한다. UML은 다양한 관점으로 모델을 표현하고 있으므로 다양한 관점의 역할 모델을 표현하여 컴포넌트를 추출하는데 활용할 수 있도록 한다.
