초록

Enterprise JavaBeans (EJB)는 컴포넌트 기반 소프트웨어 개발 (Component-based Development, CBD)을 위해 보급된 환경이다. 컴포넌트는 재사용 단위의 복합 객체이지만, EJB는 객체단위의 작은 컴포넌트이므로 다수의 엔터프라이즈 빈을 복합하여 큰 단위 재사용을 지원해야 한다. 따라서 EJB를 이용하여 컴포넌트를 상세 설계 및 구현하기 위한 구체적이고 실용적인 기법이 필요하다. 본 논문에서는 CBD의 구성요소를 EJB를 이용하여 어떻게 설계하는지의 지침과 기법을 제시한다. 단일, 복합, 화이트, 블랙 박스, 다중 인터페이스, 가변성을 지원하는 EJB 환경의 컴포넌트 설계 및 구현 기법을 제시한다. 사례 연구를 이용하여 제시한 설계 기법을 보이고, CBD 컴포넌트의 특징과 본 논문의 기법을 비교하여 검증한다. 결론적으로 EJB 환경에서 컴포넌트의 재사용성, 활용성, 이식성을 더욱 증가 시킬 것이다.

Enterprise JavaBeans (EJB) has been accepted for supporting Component-Based Development (CBD). A component is a large-grained reuse unit consisting of several objects; however, an enterprise bean in EJB is a unit of atomic object and so multiple enterprise beans should be composed to support larger-grained reuse. Therefore, we need practical methods for designing and implementing components with EJB. In this paper, we propose instructions and techniques for designing CBD elements with EJB constructs. That is, we define methods for designing and implementing single and composite components, white- and black-box components, multiple interfaces, and variability mechanism in EJB platform. We evaluate the proposed method by performing a case study and comparing the characteristics of CBD components with the method. Consequently, the method is supposed to improve reusability, applicability, portability of components in EJB platform.
