We need the flexible method for communication network configuration and fault management business procedure. Therefore development of systematic integrating fault management system is essential to meet on these requests. We must design the integrating fault management system so that can run the repair processing for both data communication network management and new next generation data communication network of various type. In general it is effective that the system is consisted of decentralized module to be accessibele for business logic and datum to remote area. To Solve these problem, a method is to use object-oriented design technique. That is, it is to abstract reusability objects and make component module using the abstracted objects. In this paper, we propose a fault management system of communication network service using object-oriented design techniques which are UML(Unified Modeling Language) and EJB(Enterprise Java Bean).

Recently, the scope of user interface is increasing the relative importance in software development dramatically. As a result, there are various relative technologies like as SWING, MFC, Web 2.0, and etc. However, most current software developments are progressed in separate development process with user interface part and business part respectively. This causes the problems, like as a difficulty in the integration process, an development period's delay, and a poor reusability for the constructed models. That is, the extendability and reusability of the created models is being decreased because UI modeling is not systematic and hierarchical, and the consistent integration technique between UI modeling and business modeling does not supported. To solve these problems, this paper proposes an unified and systematic UI modeling process based on UML, using the hierarchical metamodel according to the abstraction levels of development phase. We suggest an UI metamodel, which contains a hierarchy by layering the modeling elements in PIM and PSM based on maturity degree of the development. An hierarchical modeling process combined UI modeling and business modeling is built by applying the UI and business metamodel in terms of three modeling phases(concept/specification/concrete). The effectiveness of the modeling process is shown by applying the proposed process into an Internet Shopping Mall System. Through the exploratory results, the hierarchical UI metamodel and process can produce systematic and layered UI models. This can improve the quality and reusability of models.

UML (Unified Modeling Language)은 정해진 기호와 다이어그램을 사용하여 개발할 시스템에 대한 비전을 가지도록 하며, 시스템에 관여하는 사람들에게 자신의 비전을 알리고 의견을 얻을 수 있도록 도와주는 언어이다. 본 논문에서는 이미 설계가 완료되고 구현의 막바지에 이른 국제우주정거장 (ISS; International Space Station)을 위한 데이터 인터페이스 시뮬레이터를 ULM을 이용하여 표현한다. (중략)

The design feature of KOMPSAT-2 simulator based on object oriented design methodology in terms of unified modeling language (UML) has been discussed in this paper. Also, we present how to embed flight software into the simulator. Flight software em-bedding for KOMPSAT-2 simulator is compared to that of the KOMPSAT-1 simulator.

In this Paper is analyzed about FMS(Fieldbus Message Specification) service of FOUNDATION Fieldbus and designed using of UML(Unified Modeling Language). The FMS provides a number of services for reading, writing, and otherwise accessing objects. The FOUNDATION Fieldbus protocol is object oriented. The information in the devices is accessed in the form of objects. In FMS, the objects for configuring device and strategy in a node are listed in an object dictionary(OD). Each object is identified by an index. For example, every function block and every parameter has an index.

EJB application development environment is developing component support Object-Oriented distributed processing, it is component architecture for distributed arrangement. Application developed using EJB is component coupled for business program development easily. EJB is automatically sovled to security. resource Pooling, persistency, concurrency. transaction transparency. This Paper illustrate for EJB extract to EJB sufficient flexibility its development environment, and it was applicated remote university application domain.

정형 언어 OCL은 UML의 한 부분으로써 클래스 다이어그램과 상태 기계의 조건을 표현하는데 많은 장점을 가지고 있다. 그렇지만, OCL을 이용하여 상태 기계를 메타모델링 하는데는 적지 않은 한계가 있다. UML/OCL은 모델의 정적인 구조를 강조하지만, 시스템이나 서브 시스템의 시간과 환경에 대한 반응을 고려는 미흡하다. 또한, 시스템의 변화에 있어 시그널은 오퍼레이션과 유사하지만 상태 기계에서만 다루어진다. 결국, 시스템의 변화에 대한 고려는 상태 기계를 통하여 보다 명확하게 명세 될 수 있으며, 현재 OCL의 확장으로써 이러한 문제를 해결 할 수 있다.

컴포넌트 시장의 확산으로 소프트웨어 개발 형태가 컴포넌트 기반의 소프트웨어로 새롭게 변형되었다. COM, CORBA, EJB등은 컴포넌트 아키덱쳐들이다. 그 중에서 선의 EJB를 이용하여 만들어진 애플리케이션은 확장성 있고, 트랜잭션을 보장하며 멀티유저 환경에서도 안전하다. UB 설계의 기렬 모델링 언어인 UML을 이용한 EJB 추출방법은 UML 자체가 객체의 식별을 위한 자세한 가이드 라인을 제시하지 않으므로 EJB 추출에 어려움이 있고, 직관적인 경험에 의한 추출방법은 EJB 기반의 프로젝트를 처음으로 개발하고자 하는 개발자에게는 어려움이 있다. 본 논문에서는 정보구조 모델링의 방법[1]을 이용하여 구체적인 객체 추출방법을 제시하며 추출된 객체에서 쉽게 EJB의 빈들로 매핑시킬 수 있다.
