Abstract

Abstract:

Based on database technology, GIS technology and software engineering methods, this paper tries to design the database functionality of "China's land-based water system comprehensive simulation and virtual reality platform", which is the core software platform of the CAS Knowledge Innovation Program key project “Trans-basin water transfer and its impact on terrestrial water cycle and water safety". Using GIS software and commercial databases, a "multi-source database for regional water system" is established, with the diversity of spatial distribution, time scales, and data format, based on the integrated spatial-temporal strategy and the multi-database establishment frame, which effectively eliminate the effect of information silos, to achieve comprehensive utilization of data related to trans-basin water resources, and to provide integrated data support services for the platform.

Key words: data integration, database, database design, spatial database
