National Knowledge and Information Resources of KADO(Korea Agency for Digital Opportunity and Promotion) were distributed to the several data centers. The metadata for the resources was the conceptual level recommended standard. It was not for the integration, but the retrieval. So it is not easy to integrate to the central metadata DB or connect metadata among the data centers. In this paper, we analysed the metadata of the several data centers and provided the integrated standard model for the central metadata DB.

다중 데이터베이스 미들웨어 시스템은 기존에 이미 개발되어 사용되고 있는 여러 상이한 데이터베이스 시스템을 상향식 기법으로 통합하여 기존 데이터베이스 시스템에 아무런 수정을 가하지 않고도 사용자에게 단일한 인터페이스로 동시에 여러 데어터베이스에 접근할 수 있도록 하는 시스템이다. 이러한 데이터 통합 미들웨어 시스템은 ERP/CRM/DW/전잔상거래 등 여러종류의 데이터 저장소를 통합 접근해야 하는 분야에서 유용하게 사용된다. 본 논문에서는 한국통신에서 개발된 다중 데이터베이스 시스템인 MDATA를 종합망관리시스템 구축에 이용한 사례를 통하여 데이터 통합 미들웨어 시스템의 적용사례 및 그 유용성을 제시한다.

In this study, we developed an integrated urban river data platform that collects, cleans, and provides data for urban river management. The urban river integrated data platform has the function of collecting data provided by various institutions using the Open API service. The collected data is purified through pre-processing and loaded into a database. The collected data can be reviewed and analyzed using a visualization system and provided through the Open API, so that it can be used as individual input data by combining them in the urban river model. In addition, the development system for real-time data was developed to apply real-time data to urban river models. Through this, users will be able to reduce the time and effort required for data collection, pre-processing and input data construction, thereby increasing efficiency and scalability in the development of urban river models and systems.

기존 원격 통신 네트워크나 서비스를 위한 관리는 통합된 관리 모델(SNMP/SMI)을 사용함으로써 다양한 기반 구조의 통합을 가능하게 하였다. 그러나, 음성과 데이터의 통합, 유선과 우선의 융합, 사업자간 서비스 영역 구분으로 인하여 기존 관리 시스템은 비능률적이고, 복잡하며, 구현과 큰 네트워크에 적용하기 어렵다. 이를 개선하기 위하여 SUN에서 네트워크 관리 기술인 JMX(Java Management Extenstions)를 제공하고 있다. JMX는 어플리케이션과 네트워크 관리 및 모니터링을 위한 아키텍처이며, 현존하는 관리 및 모니터링 시스템을 통합하는 수단을 제공하여 준다. 따라서, 본 논문에서는 JMX를 활용하여 통합 네트워크 관리를 할 수 있는 시스템을 설계한다.

There are various structures in the underground space, and the structures is managed as 3D data in Integrated Underground Geospatial Map Management System(IUGMMS). The worker transmits and updates the integrated map including the changed underground geospatial data to IUGMMS with the completed book submission program. However, there is a problem in that the transmission time and the update time is delayed because the size of the integrated map file is large. In this paper, we try to extract and transmit only the changed integrated map by obtaining and comparing each spatial characteristic information of the integrated map. As a result of the experiment, the transmission time of the suggestion method is short and the update time is also short than the transitional method because the suggestion method transmits only the integrated map including the changed underground geospatial data. As a result, it was possible to reduce the delay time in transmitting and updating the changed integrated map.

For effective distributed software development, integrated information object management functions that manage the structures and relationships among information objects are most required. Presented in this paper is a managerial framework comprised of BOC (Bill Of Class) and part dictionary scheme for integrated information object management in distributed software development processes. Based on the proposed BOC and part dictionary scheme, an integrated information object management system is designed and implemented. As a result of this implementation work, the usefulness and benefit of proposed framework are also shown.

Datawebhouse consists of both web log analysis used for customer management and datawarehouse used for decision support. However, datawebhouse needs complex operations for management in order to transform and integrate data from heterogeneous data sources and distributed systems. We propose a metadata schema in order to enable data integration and data management which are essential in datawebhouse environments. We show that our proposed schema supports datawebhouse development and enables integrated asset management of business information. With ETL metadata for web log extract, we can improve the data processing time of web log.

In this paper, we propose an integrated information retrieval system for distributed multiple KRISTAL-2002 systems by using the metadata information. This system integrates current systems for different areas or systems for the same area with the different schemas so that the users can get the answers by once from the whole systems. The proposed system composes of the Source Server Manager(SSM) supporting the mapping between the integrated metadata database and source server, the Integrated Metadata Manager(ISM) for registering and managing the metadata and schema mapping, the Distributed Query Processor (DQP) for processing the user query into the source server query, the Distributed Data Set Integrated Manager(DDSIM) for transforming the total retrieval results by merging to the HTML format, and the integrated retrieval engine for managing the query results. It is assumed that the integrated metadata follows ISO/IEC 11179 metadata registration procedure with the metadata registry system which is a subsystem of the proposed system. There are two kinds of queries for users; the basic query and the detailed query. The users may select the databases or organizations for results by their own choices before giving the queries. The proposed system has been developed over KRISTAL-2002 systems with $Visual C^{++}\;and\;C^{++}-CGI$ and tested and verified with the six database systems.

The purpose of this study is to develop an efficient BIM-based FM(Facility Management) system architecture to integrate the heterogeneous solution data related to FM. The heterogeneous solution data can be an FM system, asset management system, or facility sensor database systems, as well as files created by a modeler. In this study, we define the consideration for the external heterogeneous data integration related to BIM-based FM and propose the methodology. To implement it, trends in related studies were reviewed and general use cases of BIM-based FM were derived to develop the architecture for the integration between BIM and the heterogeneous solution data. The component architecture was designed to implement the use cases, and the schema was developed for the prototype by using the proposed architecture.
