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

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.
