With the rapid growth of the B2B electronic commerce, digital catalogs for expressing product information effectively and exchanging it easily between companies become increasingly important. In this paper, we refer a product expression model to effectively integrate product information, and implement the model using XDK(XML Development Kit), which is given by Oracle 8i. We will first derive an XML DTD reflecting the model. We will then develop a system that stores and retrieves product information on/from Oracle 8i databases, which is written in XML, complying the XML DTD structure. Finally, We will give an experiment on the system.

The information exchange on the using of XML such as B2B electronic is common. So the efficient method to store XML message in database is needed. Because the ORDBMS is extended to ORDBMS for supporting multimedia application such as Oracle8i, 9i, Informix and SQL2000 server, SQL2, the standard RDB is extended to SQL3 for ORDB, And the XML application based on java such as J2EE is extended. Therefor it is necessary for the efficient connection methods based on JDBC between XML application and database system. In this paper, the methodology a transformation XML DTD to SQL3 schema is proposed. For the transformation, first the methods of transformation XML DTD to object model in UML class diagram are proposed. And then the methods of mapping transferred object models to SQL3 schema are proposed. This approach for transform::1lion XML. DTD to SQL3 schema such as Oracle8i, 9i, Informix and SQL2000 server based on java is proposed in this paper, can be used in database design to build XML applications based on ORDB.

본 논문에서는 CORBA와 Java를 이용하여 분산 객체 서버 형태의 응용 프로그램인 제품정보관리 시스템을 설계하고 구축한 사례를 소개한다. 이 시스템은 Visibroker 3.4 for Java와 JDK 1.2.2를 이용하여 개발되었으며 데이터베이스로는 Oracle 8i를 사용하였다. 특히, 지속성 객체 (persistent object) 의 지원을 위하여 추가의 추상화 계층 ( abstraction layer) 를 구현하고 있으며 전체 시스템은 객체 지향 프레임워크 (object-oriented framework) 으로 설계되었다. 본 문서에서는 제품정보관리 시스템 뿐 아니라 다른 분산객체서버의 설계 및 구현에도 참고가 될만한 설계 가이드라인 들을 제시한다.

In this paper forest fire status information management system was developed under web environment using web GIS(geographic information system) technology. Though this system, general users can easily retrieval domestic forest fire status information and obtain that in visual way such as maps, graphs, and texts if they have only certain web browsers. Moreover, officials, who have system access authority, can easily control and manage all domestic forest fire status information through input interface, retrieval interface, and out interface of the system. This system can be considered as the first domestic system to manage forest fire status data and service them in visual through user friendly interfaces on web. In order to implement this system, IIS 5.0 of Microsoft is used as web server and Oracle 8i and ASP(active server page) are used for database construction and dynamic web page operation, respectively. Also, ArcGIS IMS(internet map server) of ESRI is used to serve maps by using Java and HTML as system development languages. Not only the domestic tendency of forest fire but also the forest fire status information of certain area and time such as the frequency and the loss can be presented through distribution maps, graphs and tables. Therefore, this system is supposed to play as a important role when the policy relate to domestic forest fire is established. In addition, the self consciousness of people against forest fire can be inspired and the foundation of scientific and systemic forest fire services can be obtained through this system in the future.

In this paper forest fire statistical information management system is constructed on web environment using web based GIS(Geographic Information System) technology. Though this system, general users can easily access forest fire statistical information and obtain them in visual method such as maps, graphs, and text if they have web browsers. Moreover, officials related to forest fire can easily control and manage all information in domestic by accessing input interface, retrieval interface, and out interface. In order to implement this system, IIS 5.0 of Microsoft is used as web server and Oracle 8i and ASP(Active Server Page) are used for database construction and dynamic web page operation, respectively. Also, Arc IMS of ESRI is used to serve map data using Java and HTML as system development language. Through this system, general users can obtain the whole information related to forest fire visually in real time also recognize forest fire prevention. In addition, Forest officials can manage the domestic forest resource and control forest fire dangerous area efficiently and scientifically by analyzing and retrieving huge forest data through this system. So, they can save their manpower, time and cost to collect and manage data.
