地学信息基础数据库系统—GIS-dB3的基本结构

General Construction of the Basic Database System of the Geography Information--GIS--dB3

本文介绍了立足于微机和超级微机上的地学信息基础数据库管理系统的基本结构。它采用通用的中西文关系数据库dBASEⅢ编译语言,统一管理地学信息的质量、数量、时间、空间以及信息传输等5个方面的特性数据,以FORTRAN和BASCI编译等系统软件进行数据处理及图形的显示和绘出,即采用各系统软件所长组成了一个地学的基础系统。该系统的空间特性数据中的“边”是采用超图(HYPERGRAPH)的概念组织的。它具有原中西文dBASEⅢ的操作方便、资源广泛,一定的分类统计能力,对各软件界面“友好”的特点,并具有可广泛提供各合理子集数据并使之动态成库,足够大的的分类数及库容和一定的数据独立性的特点。

This paper introduces the general construction of the basic database of the geographyinformation based on the microcomputer and the super-microcomputer. The basic databasemanages five kinds of data, i, e., quality, quantity, time, space and information tran-sportation with C-dBASE Ⅲ compiler software. It also processes data displays figuresand plots them with the Fortran and Basic compiler softwares. The geography basic sys-tem has been formed by making use of the advantages of each of these software systems. The spatial data of the system uses the topologcal construction of the hyper graph. It has similar advantages to C-dBASE Ⅲ and also can dynamically make sub-database. Finally, some of the experiment drafts have been given.
