The Application Model of Moving Objects in Cargo Delivery System*
ZHANG Feng-li1, ZHOU Ming-tian1, XU Bo2
(1. School of Computer Science and Engineering, UESTC Chengdu 610054 China;
2. Department of Computer Science, University of Illinois at Chicago Chicago 60607 USA)
Abstract The development of spatio-temporal database systems is primarily motivated by applications which track and present mobile objects. In this paper, solutions for establishing the moving object database based on GPS/GIS environment are presented, and a data modeling of moving object is given by using Temporal logical to extent the query language, finally the application model in cargo delivery system is shown.
Key words moving object database (MOD); geographic information system (GPS); global position system (GIS); material delivery system (MDS)
