Yu Wang · Computer Systems and Applications · 2010
This paper has analyzed the functions and features of Spatiotemporal Database and its model in brief. The conception of difference storage of version is used on the basis of object-oriented spatiotemporal data model. And then,a basic method of designing Spatiotemporal Data model with less historical data redundancy and high usage of current data is discussed. A Spatial data management system with basic functionality and effective balance of storage and operation is also implemented at the end of the paper.
