  • This paper presents a design of network and database structure of the integrated system for power system operational planning and analysis that will be more economical and stable of power system operation. An alias of this system is Highly Integrated Total Energy System(HITES). The Client/server model of HITES is designed as a remote data management model. The input/output-type of application programs and Oracle server is standardized. The separated user-databases from main-database strengthen security of HITES. It is plan to do that tables and relationships are defined by database designs. The connection of application program and DBMS of HITES will be tested through database design and data construction.

  • According to database and information technology development, many interests of database quality control have being increase. The purpose of database quality control is improvement quality of data itself as well as database system to satisfy user's need. As this paper was especially written about quality control of bibliographic database, to embody complete bibliographic database, it was invested numerous errors and its case by analyzing MARC records. In addition, it was presented that high degree's cataloging education, introduction of su n.0, pporting systems, and development of intelligent quality control system for quality improvement.

  • Database administrators should be aware of performance characteristics of database systems in order to manage database system effectively. The usages of system resources in database systems could be quite different under database workloads. The objective of this paper is to identify and analyze performance characteristics of database systems in different workloads, which could help database tuners tune database systems Under the TPC-C and TPC-W workloads, which represent typical workloads of online transaction processing and electronic commerce respectively, we investigated usage types of resource that are determined by fourteen performance indicator, and are behaved in response to changes of four tuning parameters (data buffer, private memory, I/O process, shared memory). Eight out of the fourteen performance indicators cleary show the performance differences under the workloads. Changes of data buffer parameter give a influences to database system. The tuning parameter that affects the system performance significantly is the database buffer size in the both workloads.

  • Effective design of a database is essential for operating application systems efficiently. This Paper discusses database design for the automatic distribution system. Database design is a complex Process for specifying the structure of information and is decomposed in three Phases: conceptual, logical, and Physical design. In this paper, we first collect and analyze the requirements for the automatic distribution system, our target application. We also perform database design for these requirements through three design Phases. We believe that our results would contribute to the effective construction of a database for the automatic distribution system.

  • There have been an emerging interests in the importance of database tuning techniques under modem database environments in which very large-scale data should be managed. In Particular. database performance parameters should be tuned to reflect system loads appropriately. This paper presents two parameter tuning strategies, namely throughput-based and response-time-based, which tune each performance parameter accordingly. The proposed techniques are applied to two commercial database systems in the TPC-W benchmark to see the effectiveness of those methods. The results show that they can help improve system performance considerably.

  • This paper deals with the construction of database system for the human sensibility evaluation.Recently, although a great deal of research efforts have been made to find out the relationships between products and emotion, the main focus of studies have been on visual and auditory sense and less on human sensibility evaluation. Therefore, we think that continuous and systematic studies on odors and the construction of database system are strongly needed in order to enhance the competitive power of products related to them.In this paper, we developed a human sensibility evaluation database system fitted with the characteristics of our country. 쏜 design procedures of database system are presented. According to these procudures, a new database system is implemented on personal computer using MS Access and Visual and is validated.

  • Purpose : This study was to develop the nursing database for gastric cancer patients for clinical application. Method : Nursing data that development of this data base is comprehensive connected with gastric cancer patient nursing process frame to foundation as classification. Result : Each stage was processed based on the System Development Life Cycle. At the Strategy Planning stage, gastric cancer patient nursing process were analyzed. At the system Analysis Stage, database flowchart was drawn up based on frame of nursing process was drawn up. At the system Design Stage, a system was developed based on the flowchart and named the Nursing Database. The Nursing Database consisted of the patient's Basic Information, Patient's Nursing History, Discharge summary, Nursing Assessment, Nursing Diagnosis, Nursing Intervention/activity, Nursing Evaluation, Statics, Code Registration. Each element in flowchart was coded and made into a database. Nursing Assessment classified according to Gorden's Health Pattern Typology, and nursing diagnosis draws the standard 27 name of Hanguls and connected with nursing assessment. Nursing intervention and nursing activity draw 192 of thing that present in NIC, connected this with nursing assessment. Nursing evaluation is linked with nursing assessment, diagnosis and intervention by achievement availability of nursing goals. Conclusion : The biggest advantage of this database nursing process that can manage nursing information exactly and rapidly to foundation be.

  • 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 Wide Web is stored in legacy database, it is necessary for the easy connection between XML application and database system. In Oracle8i, 9i, Informix and SQL2000, DBMS vendors make upgrade to DBMS for using XML. This method of upgrade between XML application and database system is Platform-dependent and DBMS-dependent. Also It is necessary for the method of the platform- and DBMS-independent connection between XML application and database system. The methods for the connection between XML DTD and RDB schema are studied for the easy connection between XML application and database system. But the study for the easy connection between XML DTD and ORDB schema is a little. For multimedia application, we use the extended DBMS from RDBMS. It is necessary for the study to the transformation from XML DTD to ORDB schema. In this paper, for easier connection between XML application and database system, we propose the method of the transformation from XML DTD to ORDB schema using Object Model.

  • This study was carried out to develop database system using internet fur greenhouse. The database system consisted of group monitor, client monitor. server monitor and DBMS. The results of the study are summarized as follows. 1. The monitoring module, as data collection system for database. could monitor the state of the control device and the greenhouse environment. 2 The group monitor was connected to the house monitors by RS-485 communication method. Data received by the group monitor were sent to the server monitor and then stored in database server by TCP/IP and MIDAS. 3. The data of database consisted of on growing environment. control devices, operation and cultivation data in greenhouse. It was developed using MS-SQL server. 4. Remote monitoring of greenhouse was realized in a client/server environment. The client module. which was named as the client monitor. made requests to access the measurement data of greenhouse through the remote data module of the server monitor in internet environment.
