본 논문은 범정부 엔터프라이즈 아키텍처(EA)의 메타모델을 UML 다이어그램을 이용하여 개선 연구에 관한 논문이다. 여러 공공기관과 기업에서는 '범정부 정보기술아키텍처 적용'이란 전자정부 로드맵 과제로 정보기술을 그들의 경영혁신을 위한 전략적 도구로 도입하였으며, 조직 전체의 최적화 및 통합, 조직의 진화관리, 조직업무의 효율성 및 효과성 등을 제공하는 방법으로 EA를 개발 및 적용하고 있다. 하지만 EA 프레임워크에서 제안하는 메타모델들은 단순한 네모 박스와 선으로 연결된 의미가 부족한 메타모델들을 제안하고 있다. 본 논문에서는 메타모델에 의미를 부여하는 작업으로 UML 다이어그램을 이용한 새로운 메타모델 다이어그램들을 제안한다. UML에서 사용된 의미를 가진 다이어그램을 범정부 엔터프라이즈 아키텍처의 메타모델에 적용함으로써 의미적인 메타모델의 다이어그램을 통해 보다 의미 전달이 용이한 메타모델로 사용되어 질 수 있을 것이다.

Until now there have been many kinds of enterprise architecture frameworks including the DoDAF in defense domain, the FEAF in administration domain, and the TEAF in finance domain. These EAFs define EA viewpoints for supporting each domain and propose perspectives and models for each viewpoint. These EAFs provide consistent models from different perspectives that interact with each other. However, they have too many perspectives so that their complexities are too high, or they do not define enough models for concrete architecture description. Especially, they neither consider business values, that mean the ultimate purpose of an organization nor execute processes for achieving the business values. This paper thus proposes the VBEAF, business value based enterprise architecture framework that considers and executes business values in organizational business processes.

기업의 전사적 비즈니스와 IT 환경의 통합 청사진을 보여주는 엔터프라이즈 아키텍처의 효율적인 시스템 적용을 위하여는 조직의 비즈니스, 정보, 응용시스템, 기술 기반구조의 연관관계와 미래모델을 시각적으로 사용자에게 보여주어야 한다. 기존 ITAMS 혹은 EAMS 라고 불리는 시스템에 아키텍처 툴을 이용하여 EA 의 모델정보를 퍼블리싱하여 시각화하였는데 시스템과 아키텍처 툴간의 플랫폼의 이질성으로 인하여 아키텍처정보를 그래픽화하여 변환하고 해당정보를 시스템에서 보여주는데 실시간 적용이 불가능 했을 뿐 아니라 사용자의 편의성이 원활하지 않았다. 이에 본 연구는 XML 기반의 SVG 그래픽 도구를 이용하여 아키텍처 작업을 가능하게 하고 SVG 정보의 자동 생성 및 웹기반 모델링 툴을 구현하여 시스템과 모델링 툴의 단일 레파지토리화를 통하여 데이터의 이원화를 해소하고 사용자 편의성을 증대하는 패턴을 구현한다.

The performance of Enterprise Architecture (EA) in the Korea's public IT domain produces mixed results and responses. On the one hand, EA earns positive remarks and enthusiasm as a central government-wide IT governance framework with its significant IT budget saving records. At the same time, however, the response to EA at the department and agency level is tainted with disappointment, fatigue, and reluctance. This essay suggests that this is perhaps caused by the sterile lackluster concept of EA Business Architecture employed in the current EA practice of the enterprise. The possibility for liberating and reviving the concept of EA Business Architecture is explored. Various conceptual axes and branches of EA Business Architecture are identified based upon extensive EA field experience and observations, and discussions are made on how the concept of EA Business Architecture can be expanded and amplified on those conceptual axes and branched. The resulting EA Business Architecture conceptualization is consolidated into an illustrative typology for EA Business Architecture. In the end the theoretical and practical implications of the research are discussed along with its contribution and limitation.

This paper aims to design and realize movie reservation system based EJB 3.0 enterprise for standardization. Non EJB and the EJB architecture to resolve the problem with benefits to support the new architecture is a lightweight container architecture. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business EJB 3.0 is well-known architecture. Therefore, this research has the Non EJB and the EJB to solve the advantages and disadvantages developed to support the latest EJB 3.0 architecture based on the design and implementation of a movie reservation system.

This paper is concerned with the development of the requirements for railway safety support information systems. The five safety elements at the system level have been modeled based on the enterprise architecture approach. Specifically, the modeling has been carried out as follows. First, the requirements are derived according to EIA-632 process. Also, the possible scenarios on the accident-investigation-support are developed from the help of relevant personnel in the area. The developed scenarios are reflected in modeling the operational and system architectures of DoDAF approach using a CASE tool. From this architecture model, we can easily get the specifications required for the operations. These results can give the improved understanding of the railway safety system to the members of diverse teams and areas working for the system development.

In industry, it is a current trend that systems are developed by using Enterprise JavaBeans(EJB) technology for reducing the cost and the time. Thus, the architecture of EJB is getting more essential to enhance reusability, extensibility and portability of system. However little has been studied in the realm of the practical software architectures for EJB. The architecture has just bean studied in abstract level, but not in concrete level providing the method to substantiate it using the practical J2EE techniques. Just using the EJB technology doesn't guarantee the reusability of the artifacts because EJB specification provides the characteristics and architecture for only fine grained components as session and entity bean. In this paper, we propose the enterprise software architecture for the systems based on EJB and the concrete techniques for implementing that. Also, design patterns of modeling efficient enterprise architecture are represented. By analyzing both the strengths and the weaknesses of suggested design patterns, EJB design patterns which are suitable for each layer of enterprise architecture will be identified. Through the component which design patterns are applied, the architecture can support the optimized relationship between the components. Five techniques for designing components from fine grained to coarse grained based on EJB technology, and architecture design techniques including transaction and assembling techniques are proposed.

This paper proposes a cloud workflow model theoretically supported by the information control net modeling methodology as a cloud workflow modeling methodology that is mandatory in implementing realtime enterprise workflow management systems running with cloud computing environments. The eventual goal of the cloud workflow model proposed in this paper is to support those cloud workflow architectures reflecting the types of cloud deployment models such as private, community, public, and hybrid cloud deployment models. Moreover, the proposed model is a mathematical graph model that is extended from the information control net modeling methodology used in conventional enterprise workflow modeling, and it aims to theoretically couple this methodology with the cloud deployment models. Finally, this paper tries to verify the feasibility of the proposed model by building a possible cloud workflow architecture and its cloud workflow services on a realtime enterpeise cloud workflow management system.

EJB(Enterprise JavaBeans)는 Sun사에서 추진하는 분산 트랜잭션 기반의 엔터프라이즈 어플리케이션을 위한 컴포넌트 컴퓨팅 아키텍처이다. 또한 J2EE 표준 플랫폼에서 서버 측 컴포넌트를 위한 아키텍처로써, 다중플랫폼 또는 다중 서버에 이식 가능한 비즈니스 로직을 표현하는 코어 기술이다. 본 논문에서는 이러한 EJB 아키텍처에 따라 구현된 EJB 서버 시스템을 클러스터링 환경으로 확장하여 고가용성 및 확장성을 얻고자 할 때 고려해야 할 사항들과 시스템 구현에 따른 구체적인 설계 방안을 제시한다.
