Nowadays XML is used for exchanging information in e-Commerce, especially B2B. Necessity of XML DBMS has being increased to efficiently process XML data. So a lots of database products for supporting XML are rapidly appeared in the market. In this paper, we made an XML DBMS system based on Generic Data Model. First we developed XML Adaptor based on Generic Data Model and added it on relational DBMS for developing XML DBMS. XML Adaptor is composed of Query Convertor and XML Repository System. The Query Convertor parse commands that are for XML data manipulation and then call the relevant component of XML Repository System for relational database operation. The XML Repository System handles relational database operations such as create, delete, store, and etc. In this way we can use a relational DBMS for manipulation XML data. Therefor we can build more economically XML DBMS.

The article herein suggested a compound repository and a descriptive method to develop a compound knowledge process. A data target saved in a compound knowledge repository suggested in this article includes all compound knowledge meta data and digital resources, which can be divided into the three following factors according to the purpose: user roles, functional elements, and service ranges. The three factors are basic components to describe abstract models of repository. In this article, meta data of compound knowledge are defined by being classified into the two factors. A component stands for the property about a main agent, activity unit or resource that use and create knowledge, and a context presents the context in which knowledge object are included. An agent of the compound knowledge process performs classification, registration, and pattern information management of composite knowledge, and serves as data flow and processing between compound knowledge repository and user. The agent of the compound knowledge process consists of the following functions: warning to inform data search and extraction, data collection and output for data exchange in an distributed environment, storage and registration for data, request and transmission to call for physical material wanted after search of meta data. In this article, the construction of a compound knowledge repository for recommendation system to be developed can serve a role to enhance learning productivity through real-time visualization of timely knowledge by presenting well-put various contents to users in the field of industry to occur work and learning at the same time.

It has been commonly accepted for a while that a successful tool environment must provide for smooth interfaces between its tools. Recent integrated CASE environment must be-based on well-integrated data repository which supports a tightly coupled, consistent environment. For the maintenance tool, it requires a careful design of the maintenance chest's database. Information about a program exists in many different forms after analyses have been performed. It must be possible to associate and select objects for data repository from this information as necessary. This paper suggests a new integrated scheme for the data repository in building software maintenancec environment. The scheme provides many basic services, including storage and management of objects/entities and links/ relations; version and configuration control, query service, data interchange service.

The combination of data warehousing and Internet technology produces a new concept - web warehousing. Due to the availability of web technologies and the need to make prompt decisions with timely information, web warehousing is emerging as a key strategic business weapon. Yet despite the many promising benefits of web warehousing, researchers have also identified several challenges, including scalability and availability. With the rise of the Internet and data centric computing applications, the use of new Storage Area Network (SAN) technology has been spotlighted for the possibility of a new data repository for web warehousing. In this article, the two new concepts of web warehousing and storage area networks are introduced. In particular, a SAN is discussed in detail as an alternative data repository to overcome the current limitations of web warehousing.

Although abundant biology data have been accumulated in public biology databases, such as GenBank and PIR, few easy-interface services are provided for users to access or update them. We have developed a system, named BioStore, that is composed of several programs to aid users to not only access public data but also share their own data easily. The service can be used for maintaining a local database as a repository of raw data files of several public databases and distributing the data files to other users. Currently, BioStore manipulates major bio-databases and will expand to include more databases and more useful interfaces.

The purpose of this study is to investigate the current status and characteristics of research data sharing by domestic researchers by analyzing the data sharing mechanism and repository specified in DAS of papers authored by domestic researchers. To this end, in this study, papers of researchers belonging to domestic institutions published in PLOS ONE from 2014 to 2022 were selected as the subject of the study. First of all, the status of DAS's existence in the papers was identified, the types of data-sharing mechanisms were analyzed using precedent studies, and the trend of changes in each data-sharing mechanism over time was investigated. As a result, it was found that DAS was written in 99.6% of the target papers, and the types of data-sharing mechanisms were similar to international patterns, but preferred types were changing over time. Afterward, focusing on repositories among data sharing mechanisms, the number and ratio of repositories mentioned in DAS were identified, and the trend of changes in use of the five repositories mentioned a lot was analyzed in a time series. In addition, the presentation method, type, and validity of the data access point mentioned along with the repository were also investigated. It was confirmed that the top five frequently mentioned repositories account for 60% of all repository mentions, and the use of a repository dealing with data codes is increasing; in addition, it was found that most of the data access points presented with the repository were valid.

ln general, hospital information system should provide interoperability hat usually and operate independence of other HIS. This study proposes a new HIS paradigm that can be implemented within standard HL7 Interface engine and clinical data repository (CDR). We have developed an alternative architecture relying on agent solutions with distributed queries to heterogeneous databases. This architecture creates a very fine and flexible repository that can handle queries with the bases of standard HL7 messaging structure. Deploying Agent solutions to manipulate autonomy of storage management and sociality for communication with open world is another issue that keeps this system from reinventing existing wheels in medical informatics. This study the first attempt to construct CDR based private clinic. We used the information stored in the clinical patient record system of the internal medicine private hospital which is used rational database. We were searched increasing the 1,000 data entry from 1,000 to 10,000. By the result, experimental CDR showed highly efficient performance more than 6,000. In the future, the CDR can be further extended for clinical information among private hospitals estranged from EHR (Electronic Health Records).

Sharing and reusing data has become essential. Data repositories are a key tool for sharing and reusing this data. The purpose of this study is to propose the service of EcoBank, which is being built and operated by the National Institute of Ecology. To achieve the research purpose, 10 out of 123 foreign data repositories in the field of ecology registered on re3data.org were selected, investigated, and analyzed. As a result of the analysis, three services were derived in common. The three services consist of first, research data policy, second, research data quality review, and research data management training and workshops. Here, in order to share EcoBank's global data, it is necessary to register with a data repository registry such as re3data.org, and it is proposed that certification be promoted to ensure the reliability and quality of the repository.
