  • Amount of biological data information has been increasing exponentially. In order to cope with this bio-information explosion, it is necessary to construct a biological data information integration system. The integration system could provide useful services for bio-application developers by answering general complex queries that require accessing information from heterogeneous bio data sources, and easily accommodate a new database into the integrated systems. In this paper, we analyze architectures and mechanisms of existing integration systems with their advantages and disadvantages. Based on this analysis and user requirement studies, we propose an integration system framework that embraces advantages of the existing systems. More specifically, we propose an integration system architecture composed of a mediator and wrappers, which can offer a service interface layer for various other applications as well as independent biologists, thus playing the role of database management system for biology applications. In other words, the system can help abstract the heterogeneous information structures and formats from the application layer. In the system, the wrappers send database-specific queries and report the result to the mediator using XML. The proposed system could facilitate in silico knowledge discovery by allowing combination of numerous discrete biological information databases.

  • XML is a standard markup language for exchange and storage of formed or well-formed information in World Wide Web, Because the source data of XML message for exchange of information in World Woo Web Is stored in legacy database systems. it is necessary the easier connection between XML application and database systems, In Oracle8i. 9i. informix and SQL2000. DBMS vendors extend their DBMSs for XML. This approach for the connection between XML application and database system is Platform-dependent and DBMS-dependent. Therefore it is necessary the platform- and DBMS-independent approach for the connection between XML application and database system, In this paper. we modeled a set of middleware components for relational database design based on XML DTD is modeled, Those components are modeled on object-based algorithm for connection between XML application and database system.

  • Kakegawa City is located at 138 deg. E and 34 deg. 45 min. N, in the west of Shizuoka Prefecture. Its population is approximately eighty thousands and its area is 185.79 square kilometers as shown in Fig.1. The city government has been developing GIS for the purpose of land management and tax base calculation and is one of the most advanced local governments in Shizuoka Prefecture. The city government has been developing the database of various kinds of physical and social environmental information, but the city government uses small parts of the database only fur land management and tax base calculation. The purpose of this report is to show the database of kakegawa City as shown in Table 1 and propose the effective usage of the database. The database of Kakegawa City as shown in Fig.2 and Fig.3 is imported to GIS in our laboratory and reconstructed as the database retrievable from each individual land. The authors developed the retrieval system of each individual land and combined it to the reconstructed database. If our GIS is open to the public, a lot of citizens will get useful information about their environments.

  • The purpose of this study is to develop a central database and a database management system to store and manage information systematically from each module of an integrated structural design system. In order to efficiently express structural design process related to the data which is very complex, we used an object-oriented modeling methodology to propose the possibility to apply a database schema for application programs in an integrated system for reinforced concrete structural design. Based on this model, we developed an interface between each module and central database. After modeled by using object modeling technique, the database was mapped by the relational database table. Then the central database and the interface were programed by using Visual C/syo ++/, a windows environmental development tool.

  • Purpose: This study intends to make a database for hypertensive patients and middle-aged women who are visiting the Yeojoo County Health Center. While building up the database, the study reviewed the current assessment tools used in the health center, developed appropriate health care programs, and designed a computerized health care system. Method: The modeling of a database for the system was constructed by MS-Access for DBMS (Database Management System) and Visual Basic. The system is to be used only in the health center by being designed as a client server method, making it possible for many public employees to be interconnected, and enables them to retrieve and search data from the database simultaneously. Results: The health management system systematically follows nursing processes including assessment, diagnosis, intervention and evaluation. Diagnosis. once it is done according to the self determined criteria, saves time and provides appropriate health information for the members. Also, the health education program was developed to follow up on the health status of the members on a continuous basis. Conclusion: Based on these results, it is required to evaluate health care programs provided for the members by using the database system and to develop more practical health care programs. It is also necessary to connect the system to other databases. which contain information about members.

  • Many people are the latest interested in the integration of the WWW and database systems. The UCM(United CGI Management) system, which is proposed on this study, is based on the method using CGI that does not change existing servers and clients to integrate the WWW and database system. Since the CGI executable architecture executes a CGI program whenever the database is accessed, the system performance is reduced greatly when many request to the database are made simultaneously. However, the UCM system improves the system performance since it uses the integrated CGI running a daemon process. Moreover, the proposed system can use the WWW database more economically and doesn't use the SQL because it does not use a DBMS. In UCM system, we define the extended HTML tags to implement the WWW database interface and use the EXODUS storage manager for accessing the database.

  • Geotechnical information database, foundation of underground geographic information system in 2nd NGIS plan, had been developing by Ministry of Construction and Transportation since 2000. This database contains not only soil condition, such as depth, type and color of layer, and ground water level, but also engineering properties used for foundation design and construction, for instance, standard penetration test, compression test. But, it is difficult to apply this database for analyzing and designing geotechnical works, because report document is only offered. In this paper, we have developed web-based geospatial information system for the effective uses. First, underground cross-section model is generated by location, layer, and engineering properties of geotechnical information database at the realtime process. Second, earth volume, bearing capacity, and settlement is calculated and potentials of soft ground, liquefaction are evaluated through pre-defined empirical formula. This process is operated by web-based client. We wish to strengthen the application capacity through this system in construction planning and design works.

  • Rural amenity resources consist of natural, cultural and social resources. Some of resources have been surveyed in other institutes and organizations and information system about these resources has been constructed. Integrating with information of existing system or database is helpful to produce useful rural amenity resources information to users. This integration of distributed information is based on semantic integration. In this paper, we used ontology for semantic integration and introduced the method of external information integration using ontology. We designed ontology table to represent ontology in database and integrated distributed information using ontology. To examine the improvement of information service efficiency and the applicability, rural amenity resources information and tourist attraction information database were constructed and integrated. Also, the information service efficiency with information integration was evaluated using recall ratio and compared to the information service efficiency without information integration.
