Recently, as both business processes and IT systems become ever more complex. Especially, enterprise applications tend to become unmanageably complex and increasingly costly to maintain. Therefore complexity is the insidious enemy of software development. It is critical to have a methodology that recognizes and manages this enemy effectively. In this paper, we propose ISIS (Integrated System of Independent Subsystems) - the architectural style needed to develop the complex enterprise applications. The ISIS was developed to meet the challenge of reducing the complexity of a larger enterprise application today. It gives us architecture models for reducing development complexity and composite application. The enterprise application is partitioned into a collection of independent subsystems using ISIS decomposition schemes and equivalence relations. We use middleware named ISIS engine that provides a service for subsystems interoperability by enabling the integration of distributed, cross-platform subsystems. We have implemented an ITSM system that achieves our objectives, reducing development complexity, using the ISIS architecture. Finally, ISIS architecture provides greater flexibility and productivity when an organization needs either to change its business processes, or to update the underlying systems.

The trend of business work that is related to supply chain changed into e-business using the electronic document However, the small and medium enterprise organizations still use huge volume of paper document, especially in private sector. Recently, the need for eco-friendly and low cost logistics becomes increasing. For this, it has expanded to exchange or to use e-document rather than the paper or manual processing in supply chain business. Therefore, this paper proposed the electronic access system for supply chain by business process modeling. If it is using the proposed system, it can be saving the exchanged or the scanned document to system, and user can utilize that document on just accessing system whenever they need the document. We believe it might reduce the burden of each organization because they don't need to save large volume data to their system or place. Furthermore, the benefits will effect across the national as well as global.

Enterprises utilize software development strategically within digital convergence of information technology. Software development direction of IT takes advantage of new technology through integration of across-the-board data and business process standardization and integration. But, software development environment of enterprises which globalization is accelerated gradually is doing cost-cutting effort with controls and administration about various reform activity. Nevertheless, have not normalized in customer's requirement according to project, there is visual point that excessive software development integration work and administration are necessary according as connection is not harmonious with new system. Therefore, in this study, to construct these real-time integration environment, do to propose database implementation that have productivity by deent,ing N-Tiers platform for building enterprise framework with development productivity presentation, middle(business) and data(EIS) tier that take advantage of MVC design pattern.

Most of the SOA solutions applicable to businesses and organizations are taking a top-down methodology. It starts with an analysis of an organization's requirements, followed by definition of business models and identification of candidate services and ends with finding or developing required services. Challenges in adopting SOA while abandoning legacy systems involve time and cost required during the process. Many businesses and organizations want to gradually migrate into SOA while making the most of the existing system. In this paper, we propose A Method for Migration of Legacy System into Web Service(M-LSWS); it allows legacy system to be migrated into web service accessible by SOA and be used as data repositories. M-LSWS defines procedures for migration into reusable web services through analysis of business processes and identification of candidate services based on design specification and code of legacy system. M-LSWS aims to migrate of legacy system into web service appropriate for SOA. The proposed method consists of four steps: analysis of legacy system, elicitation of reusable service and its specification, service wrapping and service registration. Each step has its own process and guideline. The eligibility of the proposed method will be tested by applying the method to book management system.

Recently, enterprise systems require the necessity of integration for data sharing and cooperation. As a methodology for integration, Service-Oriented Architecture for service integration and Master Data for integration of data, which is used for service, were appeared. This paper suggests a method that operates BP(Business Process) efficiently. We make XMDR(eXtended Meta Data Registry) as knowledge-repository to support the BP and construct data hubs to operate it. XMDR manages MDM(Master Data Management) to integrate the data, resolves heterogeneity between the data and provides relationship to the business efficiently. This is composed of MDR(Meta Data Registry), ontology and BR(Business Relations). MDR describes relationship between meta data to solve structured heterogeneity. Ontology describes semantic heterogeneity and relationship between data. BR describes relationship between tasks. XMDR data hub supports the management of master data and interaction of different process effectively.

Digital environment that is represented to Internet is displacing business way of industry and business achievement way with the fast speed being giving great change on life whole. Improve existent business process utilizing Internet and Web connection technology, information superhighway to tradition industrialist manufacturer and e-Transformation's propulsion that wish to maximize productivity and administration efficiency is spread vigorously. In this paper, administration efficiency raising of Web-based factory monitoring system to do monitoring when everywhere integrating operation present condition current point of time of discrete factories in inside and outside of the country by purpose design and implemented. That is, do to normalize system structure and achievement function, and administration data of Web-based, and design using VML (Unified Modeling Language) and take advantage of ASP (Active Server Pages) and implemented web function. Implemented Web-based factory monitoring system is applying two factory (Kl, K2) of K CO., LTD. tire operation division to caravan, and application result was evaluated by very efficient thing to grasp operation situation of whole factory synthetically.

공급망관리(SCM:Supply Chain Management)는 자신의 비즈니스를 개선하고자 노력하는 대부분의 기업들에게 있어서 핵심 목표가 되고 있다. 공급망최적화(SCO:Supply Chain Optimization)는 이러한 개선 노력의 중심 목표로서 등장했으며, 보다 높은 수준의 고객 만족을 제공하기 위해, 공급망 구성원들이 최상의 업무 수행 사례를 공유하여 공급망 상호작용의 최저 원가와 최고 효율 시스템을 개발하기 위한 조직화 된 노력을 의미한다. 이러한 공급망에서 성과를 내기 위해서는 각 구성 요소들 사이의 조정과 협력이 필요하다. 그러나 기업내부와 기업외부의 환경의 동적인 면으로 인해 이러한 조정에 어려움이 있다. 예를 들면 공급업체로부터 원자재 도착시간의 지연, 생산 설비의 고장, 작업자의 질병, 고객의 주문에 대한 취소 및 변경을 계획의 변화를 유발시킨다. 몇 가지의 경우에는 지엽적으로 다루어 질 수 있지만 대부분의 경우는 공급망의 여러 기능들 사이에서 다루어져야만 한다. 이에 따라 본 연구에서는 중소기업의 각 프로세스를 최적화시키기 위해 에이전트를 이용한 e-SCM 프레임워크를 구축하고, 시뮬레이션 기법을 통해 그에 따른 성과를 제시한다.

워크플로우 관리 시스템은 모델링에서 비즈니스 프로세스 정의 데이터를 엔진으로 전송하기 위한 방법으로 정적 저장소와 동적 저장소 방식을 이용한다. 정적 저장소를 통한 데이터 전송은 로컬간 데이터 교환에 장점이 있지만 유연성과 확장성의 문제점을 갖는다. 본 논문에서는 유연성과 확장성 문제 해결 방법으로 동적 저장소 방식을 이용하며 알려지지 않는 외부 데이터의 신뢰성을 체크하기 위하여 WfMC 표준에서 제정한 XPDL를 사용함으로써 문법적, 의미적 타당성을 검증한다. 즉 XPDL 기반의 동적 저장소 전송 메커니즘을 설계하고 신뢰성 있는 데이터 전송을 위하여 문법적, 의미적 타당성 검증에 필요한 컴포넌트를 제시하고자 한다.

컴포넌트 기반 개발환경이 성숙되면서 아키텍처는 재사용 기반을 제공하는 핵심 기술요소로 인식되고 있으며, 이의 체계적인 설계와 관리를 위한 소프트웨어 아키텍처 설계개념이 중요시되고 있다. 그러나 최근 객체지향 개발 프로세스에서 클래스 단위의 하위수준 모듈에서 시작하여 컴포넌트를 도출해가는 상향식(bottom-up)설계방식이나 컴포넌트 개발에서 강조하는 패턴중심 설계기법은 비즈니스 관점의 전략적 아키텍처 설계가 불가능한 단점이 있다. 이에 본 논문에서는 기존의 아키텍처 설계 기법의 단점을 보완하기 위해 한국전자통신연구원에서 개발한 컴포넌트기반 시스템 개발 방법론인 마르미-III 에서 채택하고 있는 아키덱처 설계기법을 소개하고 이를 적용한 사례를 소개한다.
