摘要
为了利用可视化技术来对海洋渔业数据库进行质量控制 ,在综述了近年来 GIS数据库质量控制的基础上 ,首先提出了 GIS数据库质量控制的多层次概念模型 ;然后针对海洋渔业地理信息系统的特点 ,给出了海洋渔业数据库质量控制的体系结构和具体的控制方法 ,并在现有的元数据和数据仓库技术的基础上 ,提出了基于元数据的智能化控制方法原型 ;最后结合前人工作和国家 86 3计划 818主题的海洋渔业 GIS课题研究成果 。
Data quality has been the vital factor on which the reliability of the result of GIS analysis and application depends with the development of GIS. Based on the review of GIS database quality control recently research, a multi hierarchy conceptual model of data quality control is given in this paper. We can accomplish data quality control beginning with data source and then database proceeding, finally data using by this model, and then aiming at the characteristics of Marine Fishery GIS data, the detail structure of database quality control is schemed, at the same time several practical approaches of data quality control are discussed thoroughly. At last, based on the techniques of metadata and data warehouse, a prototype of intelligent data quality control is provided.
