Service Oriented Architecture(SOA) is an enterprise-scale IT architecture for linking software resources available on the network. SOA is believed to become the future enterprise solution that promises the agility and flexibility by integrating business processes through composition of the software services across enterprises. The first step for SOA construction is to identify the services. In this paper, we present a process-based service identification methodology for SOA through a case study of an IT company. Our methodology is composed of three steps: Processes (business & technical processes) analysis and systems analysis, Service candidates selection, and Service evaluation and construction planning. This framework would be practical and could be accepted to other organizations as it has been developed through the real case.

Today, s Businesses can only survive if they can sdapt fast, and this means their IT systems have to adapt too. A challenge for identifying and codifying reengineering expertise is to capture Both aspects of a successful enterprise business architecture(EBA) and suitable description language, with the contexts in which it works. In connected with the state of the art in the field of Web Services architecture and EBA, we propose to exploit the concept of business process execution language(BPEL), one among of description language. In addition, we review current a issue and problem of EAI and Workflow, and outline the main ingredients of a BPEL and EBA for building flexible Web Service. This paper is exploratory study in associated with enterprise architecture(EA) and description language.

웹서비스가 등장 하면서 주목받기 시작한 서비스 지향 아키텍처 (Service-Oriented Architecture)는 이 기종 애플리케이션 간의 상호운용성을 보장하는 웹서비스 기술의 이론적 배경을 제시할 뿐만 아니라 보다 전사적인 관점에서 시스템과 시스템 간의 연계 및 통합을 위한 방법론을 제시하고 있다. 전사적 체계통합 방안인 전사적 아키텍처(Enterprise Architecture)는 조직 내 정보 기술 자원을 효율적으로 통합, 관리 할 수 있는 방안을 제시한다. 서비스 지향 아키텍처와 전사적 아키텍처의 관계는 여러 가지 다양한 관점에서 바라볼 수 있으며, 그 관계를 바라보는 관점에 따라 전혀 다른 형태의 EA를 구축할 수 있다. 글로벌 IT환경 하에 정보체계 간 상호운용성 수준을 향상시키기 위해서는 SOA와 EA간의 관계를 명확히 이해하고, 애플리케이션 수준의 SOA적용을 넘어 전사적 체계통합 관점에서 SOA개념의 효과적인 적용방안을 찾아내는 것이 보다 더 절실히 요구된다. 본 연구에서는 일반적인 소프트웨어 아키텍처 관점에서 EA틀 구성하는 정보기술의 한 요소로 SOA를 적용하는 방안을 살펴보았으며, 비즈니스와 정보기술을 연결하는 연결고리로 전사적 차원에서 SOA를 도입, 적용하는 방안을 제시하였다.

Component-based development leverages software reusability and reduces development costs. Enterprise JavaBeans (EJB) is a component model developed to reduce the complexity of software development and to facilitate reuse of components. However, EJB does not support component assembly by a plug-and-play technique due to the hard-wired composition at the code level. To cope with this problem, an architecture for EJB component assembly is defined at the abstract level and the inconsistency between the system architecture and its implementation must be eliminated at the implementation level. We propose a component-based application development tool named the COBALT assembler that supports the design and implementation of EJB component assembly by a plug-and-play technique based on the architecture style. The system architecture is first defined by the Architecture Description Language (ADL). The wrapper code and glue code are then generated for the assembly. After the consistency between the architecture and its implementation is checked, the assembled EJB components are deployed in an application server as a new composite component. We use the COBALT assembler for a shopping mall system and demonstrate that it can promote component reuse and leverage the system maintainability.

The Korean military is aware that EA(Enterprise Architecture) is an important tool for transforming national defense and building Korean NCW, being developing the Ministry of National Defense Enterprise Architecture(MND-EA). However, unlike the importance of MND-EA, they are building MND-EA without the explicit EA governance system Many researchers have emphasized that it is difficult to develop the useful EA without EA governance. In this study, we present the EA governance framework for implementing the effective MND-EA. Through the investigation of the state of EA development and EA governance of home and abroad public institutions, we recognize the importance of EA governance, identifying the EA governance components. We set up the basic governance model consisted of principle, organization and process, designing the MND-EA governance framework by mapping the model to governance scope and target. The proposed governance framework provides direction for explicit and formal MND-EA governance system.

Automatic service identification and quality evaluation is one of key characteristics for a Service-Oriented Computing, being receiving a lot of attention from researchers in recent years. However, most researchers focus on identifying and evaluating application services and do not present methods for automatically identifying and evaluating business services from business processes. In general, the manual business service identification process by a human expert is a highly expensive and ambiguous task and may result in the service design with bad quality because of errors and misconception. We propose an automatic business service identification and quality evaluation method using Enterprise Architecture as a machine understandable knowledge-base. We verify the effectiveness of the proposed method through a case study on Department of Defense Enterprise Architecture.

This paper explores how the provided information from Enterprise Architecture (EA) affects the activities to for performing IT projects. The IT projects analyzed in this paper are projects to for developing and maintaining Korea Customs' UNI-PASS. This research was conducted based on surveys to demonstrate the effects of the information from EA on activities for IT projects. Information from EA is categorized into propriety, sufficiency and consistency. Activities for IT projects are defined as management, participation, communication, requirement management and human resource. Correlational analysis is used to measure the effects of the inf ormation on the defined activities. The analysis, which verifies the provided information by EA, does not have meaningful correlation with project management nor human resource. For public officials in charge, Sufficiency of the information produces a positive effect on decision making. For operation company, consistency of the information encourages utilization of the resources required for the project. This research suggests that strategies for performing IT projects with EA information that can support the verification of characteristic environments of each project and performance of vital activities required by the participants' roles will ensure the success of government IT projects.

In this paper. we present a definition of the term virtual enterprise (VE) and discuss some related terms and concepts. The definition was given based on Porter's Value Chain Theory. Then we discuss some positioning strategies for entering or joining a virtual enterprise from an executive's viewpoint. which show a framework for making decisions on for what. when and how a (real) enterprise need to participate or form a virtual enterprise and whom the partners should be. The major pert of the paper is on underlying information technologies and architectures for building virtual enterprises. Requirements for modeling virtual enterprises and core technologies needed for implementation are discussed. A virtual enterprise reference architecture based on NIIIP's model is presented. Finally we discuss some points that should. addressed from a macroeconomic and public policies viewpoints. These are the issues of IT standardization and investments in IT infrastructure.

This paper considers a conformity testing problem on EJB(Enterprise JavaBeans). The EJB architecture is a component architecture for the development and deployment of component-based distributed business applications. The objective is to find an optimal test sequence for the conformity test between the EJB specification and an implemented one. For the test sequence, we formulate the problem as a rural Chinese postman tour one and use a linear programming formulation. Based upon the formulations, we suggest a conformance test procedure and show its efficiency by applying the procedure to the CMP(Container- Managed persistency) entity bean of the EJB.
