Although some CASE tools supported conceptual data design, they required for users too much preliminary knowledge to learn how to use and handle them. In addition, in a number of studies on conceptual data design with natural language, they claimed passive participation for users with conforming to messages predefined by CASE tools. As an alternative to these traditional CASE tools, we proposed an ERD formulator for automated data design tool, called ERDF, so that even ordinary users, not necessarily data modeler, are capable of formulating ERD on business requirements by use of ERDF. We, first of all, introduced NSM as the standard methodology. We also designed the structure of ERDF including main controller, input controller, operation controller, regulation controller, schema controller, and output controller. We then defined conceptual domains and basic operations to lay down schema operations as well as sentence rules to handle input sentence in natural language. To get an ERD that is faithful to business requirements, we laid out supplementary design for dialogue and confirmation of soundness and completion.

Today's competitive global market makes most enterprise endeavor to specialize their business areas, and co-operate with trading partners in supply chain by the forms of collaboration, information and business process sharing. However, even the supply chain plan generated by co-operation often fails to be executed successfully, because it was generated without capacities of suppliers and more over nested suppliers. To overcome this limitation, the supply chain plan of an enterprise should be generated truly integrated way. In this paper, we classify business patterns based on scenarios about quotation processing and supply chain planning in self-integrated environment. And we present business process models about four business patterns and describe them, which are classified by whether request for quotation includes information about price, required time periods, and quantity for each required time period and whether it is received from customer or sent to supplier. In addition, we describe the types of supply chain planning problem.

Collaborative product commerce (CPC) is a newly emerging technology to support inter-enterprise collaboration through the product life-cycle. From the IT point of view, CPC is software technology to integrate product, process and resources of different enterprises using Web technologies. In this paper, we introduce a CPC framework for integrating product information across enterprises, which being developed as a part of the CPC project by ETRI. The product metadata represented by XML schema, which is compatible with ISO STEP PDM Schema standard, is presented to semantically and schematically integrate distributed product information. The web services technologies are discussed to support the interoperability of application systems related to the product development, such as CAD and PDM, where most of these applications run in a distributed environment. Finally, we implement the frame-work to integrate distributed product information.

Case-based Reasoning (CBR) is widely used in business and industry prediction. It is suitable to solve complex and unstructured business problems. Recently, the prediction accuracy of CBR has been enhanced by not only various machine learning algorithms such as genetic algorithms, relative weighting of Artificial Neural Network (ANN) input variable but also data mining technique such as feature selection, feature weighting, feature transformation, and instance selection As a result, CBR is even more widely used today in business area. In this study, we investigated the usefulness of the CBR method in forecasting success in implementing ERP systems. We used a CBR method based on the feature weighting technique to compare the performance of three different models : MDA (Multiple Discriminant Analysis), GECBR (GEneral CBR), FWCBR (CBR with Feature Weighting supported by Analytic Hierarchy Process). The study suggests that the FWCBR approach is a promising method for forecasting of successful ERP implementation in Small and Medium sized Enterprises.

Recently a new IT planning effort, Enterprise Architecture (EA), is being carried out by a number of organizations. According to many previous studies, this EA effort intrinsically differs from information systems planning (ISP). In practice, however, it is often performed just like ISP, pursuing identical objectives with just a few more modeling methods. It might lead to a misunderstanding that EA is no different from ISP. In an effort to clarify the difference, we investigate how these two planning efforts differ one from another in richness of architectural description. 19 RFP(request for proposal)s were empirically analyzed to see the difference between EA and ISP in terms of the richness of architectural description.

Enterprise Resource Planning(ERP) systems offer pervasive business functionality the applications encompass virtually all aspects of the business. Understanding and managing this pervasiveness will result in a successful and productive business application platform. Because of this pervasiveness, implementations have ranged from great successes to complete failures. This article has two distinctive parts. The first proposes and discusses a systematic process based on consulting experiences of LG CNS (leading information system company in Korea) for ERP selection. Also, the second provides the key factors that are critical to the successful implementation of ERP. The second part reports the results of a study carried out to assess a number of different ERP implementations in different organizations. A case study method of investigation was used, and the experiences of five Korean manufacturing companies were documented. The critical factors in the adoption of ERP are identified as: learning from the experiences of others, appointment of a process innovator, establishment of committees and project teams, training and technical support for the users, and appropriate changes to the organizational structure and managerial responsibilities.

정부의 행정 서비스를 보다 효과적이고 효율적으로 제공하는 것은 정부혁신의 핵심키워드이다. 이를 위한 수단으로 정부 공공기관들은 전사적 아키텍처(Enterprise Architecture)를 적극적으로 도입, 활용해야 한다. 전사적 아키텍처란 아직까지도 진화중인 개념으로 해당 기관 정보화 업무의 전 영역을 업무 프로세스(Business Processes), 정보 흐름 및 관계(Information Flow and Relationships), 애플리케이션(Applications),데이터 명세 및 관계(Date Descriptions and Relationships), 그리고 기술 하부구조(Technology Infrastructure)로 구분 짓고 각각을 구조화된 산출물로 정리함으로써 공공정보화의 청사진을 제시한다. 이렇게 구축된 아키텍처 결과물은 기관 내 뿐 아니라 타 기관 EA와의 연계를 통해 상호 운용되어야 하며, 이 과정에서 어휘의미중의성(Word Sense Ambiguation)등 상호운용성 문제가 핵심 이슈로 대두되리라 예상된다. 공공분야로 한정짓더라도 200여 정부부처 EA간의 상호운용성 문제는 정부조직 간 경계를 넘어 통합된 EA정보를 취합, 활용하는 데 있어 가장 큰 장애요인이 되리라 예상된다. 본 논문에서는 온톨로지를 사용하여 각기 서로 다른 EA간 상호운용성 문제를 해결하는 방안에 대해 논의하고자 한다.
