  • The Gateway Server Authorization System(GSAS) presented in this thesis is a database authorization system. GSAS is responsible for user\`s authorization, and privilege management, audit service. Only users that are filtered in GSAS can access the DBMS(Data Base Management System) through middleware. GSAS is located at the DBMS and already contains an authorization record for user accessing a specific DBMS. GSAS on consists of several components, namely an authorization manager, a privilege manager, and an audit manager. As an authorization manager and a privilege manager can only approve a pass at the same time, a user can get accessibility for DBMS.

  • HTML is unstructured document because of using restricted tag. HTML is difficult to extract data from HTML document. But XML is able to use user definition tag, that is easy to store information. Also XML is easy to extract data from XML document. This is the reason why XML is a standard for data exchange format on the Internet, so XML is fitted to exchange data between heterogeneous DBMSs(DataBase Management System). In this paper, we designed and implemented of XML web agent for data replication between heterogeneous DBMSs. A XML web agent system controls data of DBMS, and generates a XML document from data of DBMS. Also XML web agent is data exchange or replication between heterogeneous DBMS by the medium of XML.

  • As a result of the recent water resources crisis, development of water management automation system becomes important. This system should be developed with open architecture in order to flexibly meet the spacial and time change of irrigation water demand. Thereby, water management automation system requires open architecture and suitable software program. This study presents an application of object-oriented methodology for Open Water Management Program(OWMP). Accordingly, OWMP provides a high degree of reliability which allows modification of parameters by change of region or time to be possible. OWMP consists of Data Base Management System(DBMS) and Model System. DBMS makes it possible to analyze data related with planning water schedule and establishing database. Model System calculates reservoir inflow, reservoir effluent and basin water demand. An operator decides the reservoir operation with results of Model System and DBMS. OWMP could be adapted to the planning and decision for saving water.

  • In nuclear power plants, nondestructive examinations(NDE) plays an important role in ensuring the integrity and reliability operation. As the number of plants and operational time increased, manual handling of voluminous data associated with PSI/ISI(preservice/inservice inspection) could result in many errors or mistakes in writing the examination plan or other reports. Several new approaches to process the data have been attempted and DBMS(Data Base Management System) has been well known concept with a faster and more accurate data processing. This paper proposes an application program, called NDTSYS designed with DBMS in micro computer. The program could be used for a tool to add new records to a data base, change existing records, delete records and request reports with the data base. It would be helpful to the user who manage the PSI/ISI data with minimal time and effort.

  • Recently a strong request for the improvement in irrigation water management in order to flexibly meet the spacial and time changes of water demand for agricultural and other uses by saving agricultural water. Thereby, the purpose of this study is to design of Basin Water Management Program(BWMP). BWMP is operate with Open Control System. Accordingly, BMWP is easy to acquire data and control irrigation and drainage facilities. BWMP are consist of Data Base Management System(DBMS) and Model System. DBMS make it possible to analyze data related with planing for water schedul and establish database. Model System are calculate reservoir inflow, reservoir effluent and basin water demand. Finally, operator is decide reservoir operation in consider of Model System and DBMS. BWMP might be nicely adapted to the planning and decision for saving water.

  • 본 논문에서는 현재 한국항공우주연구원에서 수신, 저장하고 있는 MODIS 영상자료에 대한 DBMS (DataBase Management System) 구축 및 DB (DataBase) data 입력 S/W 개발 결과에 대해 설명한다. 우선, MODIS 영상자료의 DBMS를 구축하기 위한 DB table를 설계하였고, 이를 근거로 Oracle 9i를 사용하여 MODIS DBMS를 구축하여 운영 중이다. MODIS DBMS에 자동으로 MODIS 영상자료의 DB data들이 입력되도록 하기 위해, 첫 번째로 Visual C++를 사용하여서 MODIS DB table에 대한 DB data를 추출하는 ‘getatt.exe’ S/W를 개발하였고, 두 번째로 Visual Basic의 ADO를 사용하여서 ‘getatt.exe’ S/W로 추출된 DB data를 MODIS DBMS에 입력하는 S/W를 개발을 마무리하였으며, ‘getatt.exe’ S/W와 MODIS DBMS 입력 S/W를 한 개의 S/W로 통합하는 작업이 완료되어, 지금현재 한국항공우주연구원 내에서 정상적으로 MODIS DBMS가 운영 중이다.

  • As R&D(Research and Development) is going on actively to develop technologies for the ubiquitous computing environment, which Is the human-oriented future computing environment, GIS dealing with spatio-temporal data is emerging as a promising technology. This also increases the necessity of the middleware for providing services to give interoperability in various heterogeneous environments. The core technologies of the middleware are real-time processing technology of data streams coming unceasingly from positioning systems and data stream processing technology developed for non-spatio-temporal data. However, it has problems in processing queries on spatio-temporal data efficiently. Accordingly, this paper designed and implemented the spatio-temporal middleware that provides interoperability between a mobile spatio-temporal DBMS(DataBase Management System) and a server spatio-temporal MMDBMS(Main Memory DataBase Management System). The spatio-temporal middleware maintains interoperability among heterogeneous devices and guarantees data integrity in query processing through real-time processing of unceasing spatio-temporal data streams and two way synchronization of spatio-temporal DBMSs. In addition, it manages session for the connection of each spatio-temporal DBMS and manages resources for its stable operation. Finally, this paper proved the usability of the spatio-temporal middleware by applying it to a real-time position tracking system.
