  • Quality elements and evaluation methods should be considered according to the characteristics of spatial database. The purpose of this study is to propose specific methods for quality evaluation focusing on land database which are an important parts of spatial database. Through the study, of quality evaluation for selected quality elements are specified, which are based on the construction processes of the topogaphical database, cadastral database, and zoning database. Position accuracy, attribute accuracy, consistency, completeness, temporal accuracy, believability, and lineage are selected as the quality elements of land database. A various statistical and mathematical skills are proposed for measurement and assesment methods of quality elements.

  • ALTIBASE is the relational main memory DBMS that enables us to develop the high performance and fault tolerant applications. It guarantees the short and predictable execution time as well as the basic functionality of conventional disk-based DBMS. We present the 'overview of system architecture and the performance analysis with respect to the various design choices. The assorted experiments are performed under the various environments. The results of TPC-H and Wisconsin benchmark tests are described. We illustrate the performance comparisons under the various index mechanisms, the replication models, and the transaction durabilities. A performance study shows the ALTIBASE system can be applied to the wide area of industrial DBMS fields.

  • The purpose of this study was to design an extensive evaluation model for the quality of web-based database and to make a comparative analysis of People's awareness of the importance of assessment indices. The evaluation standard developed in this study was constituted by 19 indices and 45 elements in three different areas, including data, service and effectiveness. And a survey was conducted on database experts and nonprofessional users to find out their awareness of the importance of web-based database evaluation elements, and the findings of the study might contribute to laying the foundation for expediting more in-depth research efforts in the future.

  • This study aims to evaluate the quality of CD-ROM databases: Korean MARC on Disc and Korean National Bibliographies on CD-ROM. The five criteria(accuracy, completeness, consistency on the quality of data itself and ease of use, variety of retrieval function on the quality of database services) are used to measure their quality. The purpose of this study was to diagnose the quality of two CD-ROM databases mentioned above and to analyses the measured result of quality comparatively and to find out the problems of them and also to provide possible suggestions for their improvements.

  • 인터넷에 기반한 학습 콘텐츠가 보편화됨에 따라 이에 대한 사용자들의 요구도 다양화되고 있다. 이중 컴퓨터에 기반한 평가(CBT: Computer Based Test) 시스템은 학술적으로나 경제적으로 최근 그 방법론이 평가 및 개발 분야에 있어 다양하게 진행되고 있다. 그러나 현재 개발된 대부분의 CBT 시스템 환경은 관계형 데이터베이스에 기반하여 개발되었기 때문에 다양한 형태의 문제를 구현하기 어려울 뿐만 아니라, 관리 측면에서도 높은 비용을 요구한다. 본 연구는 이러한 문제점이 문항 정보는 동적인데 비해, 기존 전산 정보 환경은 정적인 것에서 비롯되었다 보고, 이에 대한 구조적 해결책을 제시하기 위해 최근 그 사용이 급증하고 있는 XML(eXtensible Markup Language)을 이용하였다. 컴퓨터 환경 관점과 문항 저작 관점 모두를 충족시키기 위해 XML의 요소(element) 정의는 컴퓨터 친화적(computer friendly) 요소와 콘텐츠 친화적(computer friendly) 요소로 분류하고, 각 요소별로 중복되지 않는 정보 유형을 추출하였다. 본 연구결과를 활용할 경우 기존 관계형 데이터베이스에 비해 동적인 정보를 손쉽게 구현할 수 있을 뿐만 아니라, 다른 XML 문서와 동기화 작업을 거칠 경우 문항 세트를 손쉽게 확장할 수 있어 경제적이고 관리가 용이하여 관련 분야 연구를 촉진할 것이다.

  • This study aimed to improve our understanding of users' cognitive processes based on think aloud protocols generated during the retrieval process of an online database. It analyzed think aloud protocols generated by participants while performing pre-defined tasks using an online database. The protocols were encoded using the open coding method. As the results, four broad categories including retrieval, system format, system functionality, and information were drawn, and 21 detailed categories were generated. Based on the results, suggestions for the design of online databases were provided.
