형상관리가 소프트웨어 개발과 유지보수 단계에서 중요하게 사용되고 있다. 연구와 실제 구축을 거듭하면서 형상관리는 소프트웨어 개발의 성숙한 기술이 되었다. CBSD(Component Based Software Development)는 소프트웨어 개발의 새로운 패러다임으로 자리 잡고 있다. 즉. CBSD가 소프트웨어 재사용과 소프트웨어 컴포넌트 기술에 관한 연구로 시작되어 왔고. 소프트웨어 개발에 새로운 패러다임으로 인식되고 있다. 그러나 CBSD에 관한 형상관리 연구가 뒤따르지 못하였고, 관련 문헌도 상당히 미흡한 실정이다. 본 논문에서 설계한 모델은 CBSD를 더 효율적으로 지원하기 위하여 사용될 것이다. 또한 본 모델은 CBSD 개념을 이용한다. 이 모델은 전통적인 소프트웨어 형상관리(SCM ; Software Configuration Management)와 관련이 있고 이를 컴포넌트 환경을 지원하도록 개선시킨 모델이다.

In this paper, we propose a steering concept that considers overall aspects in the CBSD (Component-Based Software Development) environments. While many researches which are concentrated on using components, market promotion and component development itself seem to be insufficient. To overcome this problem, we introduce a brokerage concept called“Value-Added Brokerage Concept”that provides the following three services：1) domain architecture-based component promotion, 2) intelligent component search, and 3) white-box service. Domain architecture-based component promotion facilitates balancing component production and promoting architecture-level large scale reuse. Intelligent component search enables to overcome the long time search and selection problem. Finally, white-box service is for solving maintenance problems, which is one of the most critical problem in the CBSD environments. Especially, we expect this proposed concept would be well adapted to our national environments.

Component-based software development [CBSD] is a new paradigm of recent software development. CBSD was started from reuse of software and study on software component technique. In order to improve produce and quality of software development, there is study on reuse of components lively and how to develop, share, and manage components effectively. In this study, I would like to suggest a method that is able to simply test a new application system by developing systems developed individually into components, registering them, and combining them.

Component-based software development (CBSD) has been recognized effective reuse techniques for software development by many of researchers and companies. The purpose of CBSD is to produce a high quality software system quickly through using verified software component which is contained fine-grained business logics. This paper suggests the metrics and techniques for to extract component and its interface from legacy object oriented application. For extract component, we apply metrics to measure complexity, cohesion and coupling to the legacy system.

소프트웨어 시스템에 대한 요구사항이 증가하고 그 규모가 점차 거대.복잡해짐에 따라 시스템을 개발하기 위한 절차, 방법 등이 무수히 생겨나게 되었다. ISO/IEC 12207 소프트웨어 생명주기 공정 표준은, 존재하고 있는 소프트웨어 개발 및 유지보수에 대한 절차 및 방법에 대한 일반적인 지침을 제시하기 위해 제정되었다. 이 표준은 표준 자체의 특성의 하나인 보편성을 유지하기 위해, 특정 프로세서 모델에 치우치지 않고 기반 표준(Base Standard)의 성격을 갖는다. 결국 표준은, 어떠한 프로젝트에서 어떠한 프로세스 모델을 사용하고 임의의 방법론을 사용하든 모든 경우에 적용될 수 있어야 한다. 그런데 최근 소프트웨어 산업의 새로운 패러다임으로 받아들여지고 있는 컴포넌트 기반 소프트웨어 개발(CBSD)환경에서는, 전통적인 개발환경과 많은 차이점을 지적하며 새로은 개발 프로세서들이 제안되고 있다.[4]. 따라서 본 논문에서는 CBSD환경에서의 ISO/IEC 12207 표준의 적용성을 고찰해보고 표준의발전, 개선 방향에 대해 모색해 보고자한다.

An application in Component-Based Software Development (CBSD) is built by 'composing'two kinds of components; One is a component that is made by current developer himself, and the other is a component that is from other developments. We define the former as a 'White-box component' and the latter as a 'Black-box component.' The error from the composition can be said to be caused by interactions of Black-box components and White-box components. This paper proposes a new testing technique for composition errors, and applies the technique to Enterprise Java Beans component architecture. Our technique selects test cases by injecting a fault only into the specific parts of a White-box component. This specific parts for injecting a fault are selected by analyzing composition patterns, and lead to make our test cases have a good effectiveness. We show the effectiveness of our test cases through an experiment. Moreover, we also mention an automation tool for our technique.

As a plan to counteract solving software crisis, the technology that is called Component Based Software Engineering (CBSE or Componentware) is introsuced. Component Based Software Developement (CBSD) Processes as one of the technique among CBSE have been proposed. Component specification activities among CBSD Processed are necessary and important for generating feusable component. However, the existing CBSD processed can't ensure the correctness in requirements are reflected. In this paper, we propose that formal activities wgich specify component using formal specification language Z which is verified with the ability of analysis and logicality. The proposed activities are composed of 5 tasks and 12 subtasks. By presenting specific 19 products, it is also proposed that component specification activities which are the base of CBSD for reusing. The proposed activities are able to improve qualities of component through correctness and verification of requirements specification of users in the early step of component-based software process.

Recently. component-based software development is getting accepted in industry as a new effective software development paradigm, Since an introduction of component-based software engineering(CBSE) at later 90's, the CBSD research has focused largely on component modeling, methodology, architecture and platform, However. as the number of components available on the market increases, it becomes more important to make metrics to measure the various characteristics of components. In this paper. we propose metrics for measuring the complexity, customizability, and resuability of software components, Complexity of metrics can be used to evaluate the complexity of components Customizability is used to measure how efficiently and widely the components can be customized for specific requirements organization, Resuability can be used to measure the degree of features that is reused in building applications.

Component-based software development(CBSD) is gaining popularity Effective search and retrieval of desired components, which are stored in a component repository, is a very important issue in CBSD. In this paper. a new weighted synaptic connectivity matrix is proposed to find more appropriate components. An algorithm is proposed for effective search with NOT operator and a proof for the algorithm is Presented . A new procedure to calculate the output vector for a logically combined query is also presented.
