  • The database integration is being emphasized to one way of the companies collaboration. To database integration, companies are use like one database what their own, it can be provided more efficient service to customer. However, there exist some difficulty to database integration. that is the database security and database heterogeneity problems. In this paper, we proposed the MapReduce based p2p DBaaS hub system to solve database heterogeneity problem. The proposed system provides an environment for companies in the P2P cloud to integrate a database of each other. The proposed system uses DBaaS Hub for a collection of data in the P2P cloud, and use MapReduce for integrating the collected data.

  • Purpose: As Koryo Hand Therapy is generally referenced by a manual, we made a database system to ease. Method: Using the basic theory of Koryo Hand Therapy with the System Development Life Cycle (SDLC), we tested, analyzed, designed and implemented the system and constructed a database system with MS Access according to the symptoms. Results: We constructed the database system of Handing and the symptoms of Koryo Hand Therapy in 3 parts (Basic Data Management, Disorder Therapy Management, Report) for easy management. This database system will be useful for general users to protect, promote and measure their health. The structured database system was valued on the basis of the students basic knowledge of Koryo Hand Therapy. As a result, 80% of the respondents answered that the "system is well structured", 78% that "it's convenient to search", and 87% that "it's helpful for self health management". Conclusion: These study results provides people with information on the basic treatment of symptoms for the self health protection and promotion with Koryo Hand Therapy by constructing a database.

  • In the complexity and diversity of modern society, there is an urgent need for an information system which can systematically collect, manage and analyze data. Especially in the discipline of nursing, a nursing informarion system is necessary to maximize nursing resources and improve nursing care in the present system which is faced with increases in client needs and multiple changes in hospital environments. This research was done to provide a basis for the development of an integrative nursing information system for the future, by designing dababases items which were extracted from an analysis of the ward nursing information system on general wards excluding the OPD, ICU, OR and CSR with functions using a different system from the wards, and the design of output screen used the database items. The ward nursing information system was analysed through analysis of nursing practice related to recordings, such as the worksheet, kardex, and other nursing practice recordings, on 25 wards. The development of the database was the part of the construction of hospital information system and used the database development life cycle which is related to the system development life cycle. The database development steps included selection of database management system and design of a physical database following the principles of the order communication system which is been developing at Y University Hospital. Conceptual database and Logical database were designed using the base of 25 data items and fields derived from analysing the worksheet, the data items and fields derived from the kardex and other nursing practice recording, from these 19 data base tables were framed through transforming the relational database. Through this process, four types of output material for nursing practice recording which nurses can carry and use during their nursing practice were produced.

  • Conventional database retrieval system have problems of being able to select data out of database only if the data exactly equal to retrieval conditions offered by users. If there are no data in database which exactly equal to users retrieval conditionals, the system can not provide adequate data. To solve these problems, cluster increase of FCM and re-initialization of algorithm were suggested in this study. And by interlocking knowledge-based database, built with FCM, to image database, new retrieval system was built to provide the data which are most appropriate for the requirement of users. We applied this new retrieval system to gift selection database system in pamphlet of mail order, and confirmed its effectiveness.

  • The explosive Increase of wireless networks and the advancement of mobile devices lead to the expansion of mobile environment. In accordance with the development of mobile environment, the need to use mobile database is increased sharply, and also it accompanies the related problems. The current mobile database system is based on the centralized method from which a synchronized server manages multiple mobile database management system to synchronize. From this mobile system architecture, several kinds of problems can be detected such as the management of synchronization issues between mobile databases and the transaction management issues. Furthermore, the current mobile database management system does not consider any solution on the fault tolerance. To solve those problems, this paper proposes the mobile agent-based mobile database management system. The proposed system provide high confidence and efficiency by enhancing the network efficiency and fault tolerance through the mobile grouping.

  • In a centralized database system, all system components reside at a single platform. In recent years there has been a rapid trend toward the integration of information systems over multiple sites that are interconnected via a communication network, and users' needs are changed to integration of multiple information sites. Multi database System is one of solutions for integrating distributed heterogeneous databases. However the problems in multi database system are restriction in distributed environment support, limitation in integrating heterogeneous media type data, static integration, and data-only of integration. In order to solve these problems, we propose a hybrid database integration model, HyDIM. HyDIM is used for the integrating legacy multimedia data, adopting CORBA, MDS, and mediator. We demonstrate a prototype system far PDM application domain.

  • This paper presents a geotechnical information system(HGIS) developed for Korea Highway Corporation. To make a database for boring information, characterization study of boring data is carried out. Based on tile study, the HGIS database is developed as a relational database. The HGIS database consists of 23 tables including 13 reference tables. For an effective database management, a boring log program called GEOLOG is developed. GEOLOG can print boring log and store those data to tile HGIS database.

  • Objectives : KIOM(Korean Institute of Oriental Medicine) built up korean medical paper database and services it through information portal OASIS. The database are updated about 1,600 papers and 48,000 references annually. Because lots of manpower and time are needed to update database, it is very important to raise up efficiency and quality of it. Methods : In this paper, we implemented web based database building system utilizing pre-built OASIS' database to improve the working process, data quality and ease of management. Results : First we designed and implemented web based system to input bibliography of the paper efficiently. It raised efficiency using OASIS' paper and reference database. Second we improved the refining process using web based system to raise up data quality. And third we developed the manager functions of web based system to control and check the working process. Conclusions : If we add korean medical dictionary and link outside paper database in the future, we hope that work efficiency and data quality will be raised more. And because the database schema of OASIS system and developed system are different, we are implementing the data transformation system.

  • It is difficult to support collaborative design with a conventional ship CAD system which manages design information using files. In this research, file storage has been replaced with a database. This paper describes the OpenDIS which is an interface between the geometric kernel and the database. Its main purpose is to implement the CAD system which has the STEP database as the native storage. A prototype CAD system has been implemented using that OpenDIS interface which is implemented by OpenCascade geometric kernel and the Objectstore object-oriented database. The STEP methodology is used as the database schema. This CAD system has been applied to the hull design of a ship in order to verify the usefulness of the interface.
