  • We must have a schema conflict resolution method for integrating local schema on content integration and management system. But The Past method is inconsistent and depends on local and global databases. In this paper, we propose the management method of schema confilct using XML that can represent and interchange the structual information of schema.

  • [1] and [2] present an approach to diagnosing possible defects in the mechanical systems of a nuclear power plant. In this paper, by using a fault library as a database and training data, we develop a diagnostic algorithm 1) to decide whether an Air Operated Valve system is sound or not and 2) to identify the defect from which an Air-Operated Valve system suffers, if any. This algorithm is composed of three stages: a neural net stage, a non-neural net stage, and an integration stage. The neural net stage is a simple perceptron, a pattern-recognition module, using a neural net. The non-neural net stage is a simple pattern-matching algorithm, which translates the degree of matching into a corresponding number. The integration stage collects each output and makes a decision. We present a simulation result and confirm that the developed algorithm works accurately, if the input matches one in the database.

  • In this paper, we suggest an XML Development Support(XDS) System as a good developing tool to solve the problems that related with the database integration, increased to the developing terms and costs when the developing of XML programming base on the web server. XDS System is designed for the purpose of easily coding the XML program, of simply changing the programming structure and of completely maintaining the program environment. According to the predefined policy, XDS System provides necessary informations such as tables, columns, or relational keys from Database for developer. The developer step by step selects or sets what he needs. And XDS System creates an XML Tree with the result of selected information. The XML Tree includes all information of making an XML Schema and some XML Stylesheet. XDS System creates an XML Schema for all clients and creates many XML Stylesheets for each client using the XML Tree.

  • As information renewal period comes to be quick recently, the need that IRS must have data management facilities such as transaction processing, join, view, trigger is extending. Therefore, DB-IR(Database ? Information Retrieval) Integration is a recent budding area of interest in the research fields of database area and information retrieval area. Since the role of DB-IR integration systems is different from those of DBMS or IRS, It is necessary to be a new design of structure for DB-IR integration system. We have designed a new server structure for efficiency and stability of DB-IR integration system.

  • To establish an infrastructure for technology and information in the domestic construction industry, several construction regulations pertaining to construction information have been institutionalized. However, there are major problems with the domestic information classification system, earned value management (EVM) and project management information system (PMIS). In particular, the functions of the current PMIS have consisted of a builder-oriented system, and as EVM is not applied to PMIS, the functions of reporting, analysis and forecast for owners are lacking. Moreover, owners cannot confirm information on construction schedule and cost in real time due to the differences between the EVM and PMIS operation systems. The purpose of this study is to provide a framework that is capable of operating PMIS efficiently under an e-business environment, by providing a proposal on how to establish a work breakdown structure (WBS) and an EVM - PMIS integration model, so that PMIS may provide the function of EVM, and stakeholders may have all information in common. At the core of EVM - PMIS integration is the idea that EVM and PMIS have the same operation system, in order to be an activity-based system. The principle of the integration is data integration, in which the information field of an activity is connected with the field of a relational database table consisting of sub-modules for the schedule and cost management function of PMIS using a relational database management system. Therefore, the planned value (PV), cost value (CV), actual cost (AC), schedule variance (SV), schedule performance index (SPI), cost variance (CV) and cost performance index (CPI) of an activity are connected with the field of the relational database table for the schedule and cost sub-modules of PMIS.

  • In this paper, Java Method approach for the integration of Web and Object-Relational DBMS is proposed. For the purpose, we extend to use Java language in programming user-defined function which is one of important characteristic of Object-Relational DBMS with object concept. Therefore we can retrieve not only database objects but also their associated Java methods to run in clients. Finally, to demonstrate the feasibility of the proposed Java Method technique, we designed and implemented this Java method system based on three-tier client/server architecture using JDBC(Java Database Connectivity) and Java RMI(Remote Method Invocation).

  • Data Grid is a kind of Grid computing provides the cooperative environment through the distributed data sharing, and can manage the massive data easily and efficiently. We designed and implemented Globus Toolkit4 (GT4) based database access and integration service (GDAIS). This service was implemented as Grid service for run on the GT4 which is Grid middleware. And it provides functions which are automatic registration of database in virtual organization, distributed query service, and the unified user interface. Also this system can use components which are provided from GT4. Therefore it can improve the efficiency to distribute and manage databases, can easily access and integrate of the distributed heterogeneous data in Grid environments.

  • This paper constructs ERD thesaurus that is storing information about Entity Relationship Diagram(ERD), and proposes an ERD thesaurus-based methodology for view integration in an important conceptual design step in designing databases. To show the usefulness of proposed methodology, the prototype for view integration support system is implemented for the applied case. As a result, ERD thesaurus-based methodology is more effective than the existing methodologies for view Integration in the aspects of affinity analysis, semantic conflicts resolution, and view Integration processes. Therefore, our methodology is expected to be utilized in integrating the existing fragmented schema or designing a large database integration.
