  • 데이터베이스 품질문제는 학문적으로나 실무적으로 상당한 관심을 모으고 있지만 아직까지 많은 문제들이 풀리지 않은 상태로 남아있다. 본 연구는 DB 품질에 관한 다양한 관심과 문제들을 분석하고, 이 분야에 관한 체계적 연구흐름의 출발선을 찾고자하는 노력의 일환으로 시도되었다. 우선 지금까지 발표된 관련 연구와 현재 실무에 종사하는 전문가들의 견해를 종합하여 DB 품질에 관한 연구 프레임워크를 고안하고 그 속에서 다섯가지 연구영역(품질기준, 품질측정, 품질등급, 품질관리, 품질인증)을 제안하였다. 그리고 DB 품질을 분석할 수 있는 일곱개의 품질기준(정확성, 완전성, 일관성, 현행성 검색성능, 사용용이성, 사용자지원성)을 추출하고, 각 기준별로 이론적 정의를 시도하였다. 그리고 현실적으로 가장 논란의 여지가 많은 계량적 측정도구, 즉, 설문조사에 사용될 68개 문항과 척도를 개발하였다.

  • This study aims at preparing the foundation for continuous development of Topographic DB by suggesting an actual quality improvement scheme and proposing a draft for complementing existing progress and method of implementation and management according to this scheme. For this purpose, we surveyed the Topographic DB users to grasp the current DB quality and the required quality level. Then, the suggested quality improvement scheme was concertized and verified through an experimental research. The experimental research was concentrated upon evaluating primitive data, modifying geometrical and logical errors and management. At last, a plan to improve the related systems was proposed.

  • Due to recent climate change, lager-scale storm and flood disasters have occurred. To prepare for this, the government is operating the national disaster management information system(NDMS), it is insufficient that unification and standardization of disaster site information data. In this study, to establish a disaster information display system, spatial DB was stored, quality standards were presented and the quality of spatial information currently provided was evaluated. As a result of evaluation, spatial information is established as different standard for each institution. So it is difficult to integrate and use. It considered that prepare a common standard to redeem this difference.

  • The purpose of this study was to propose applicability of spatial data and quality check criteria for estimating damage from storm and flood. Using the data from the National Disaster Management System and National Spatial Data Infrastructure, spatial database for estimation of storm and flood damage has been mapped to each type of damage. This was proposed as the quality check criteria for damage analysis. Through this study, it is possible to utilize the spatial database for estimating storm and flood damage. The reliability of analysis results are ensured through the quality check criteria.

  • This study concerns DB quality of the Web databases which has been produced in medical science. For the quality evaluation of Embase and PubMed, 10 evaluating criteria were developed on the basis of literature review. The evaluation result showed that PubMed has superiority to the currentness, accuracy, completness, consistency, ease of use, customer support, searchability, cost, and network & H/W on DB, but Embase has only superiority to the coverage. It is needed for purchasing, user training, and library service based on the above evaluation result.

  • 해양생물다양성 자원에 대한 국가 주권을 인정하는 해양생물다양성협약의 발효로 생물다양성 자원을 확보하기 위한 세계 각국의 경쟁이 치열한 상황이다. 현재 우리나라 각 기관 및 대학들이 보관하고 있는 해양생물자원 정보가 산재되어 있고, DB에 대한 관리 미흡으로 인하여 학술적, 산업적 활용이 어려운 상황임을 인지하여, 통합적으로 관리할 수 있는 정보체계가 필요한 시점이다. 본 논문에서는 해양생물다양성 자원 중 고품질 해양생물자원에 대한 현황을 분석한다. 그리고 해양생물다양성 데이터 고품질 확보 방안을 위한 DB 품질 오류율 산정 기준을 적용하여 메타DB 구축 방안을 제시한다. 본 연구는 향후 해양생물자원에 대한 국가전략수립에 기여할 것으로 기대한다.

  • BIS is an arrival guidance system which is able to supply passengers with bus service condition via Kiosks at a bus stop, internet and mobile service through pinpointing bus location in real time. It is very significant to improve the quality of traffic information by quality control of GIS-based bus network so as to maintain navigational information and to implement reliable BIS. Therefore this study aims to build criteria to quantitatively evaluate data quality of the product in accordance with the process in bus network data and to suggest guideline of quality control. To achieve this, we have categorized geometric and logical errors occurring during constructing bus network database by giving a specific case study on TAGO and set up sectional guideline and procedures to examine database for systematic and coherent quality control management. Proceeding from what has been said above, the outcome of our research leads to quality guarantee for objective and reliable bus network database and is fully expected to bring benefit of providing a more accurate public transportation information and improving reliability of BIS through preventing a variety of errors in system operation in advance.
