With the rapid development of geographic information system (GIS), computer aided design (CAD), mobile computing and multimedia databases, spatiotemporal databases have been the focus of considerable research activities over a significant period. It becomes an enabling technology for important applications such as land use, real estate, transportation, environmental information systems, energy resource et al. In this paper we address research issues in spatiotemporal databases. We first proposed an integrated spatiotemporal data model, and then we provided novel threetier architecture for implementation where Meta tables to handle spatiotemporal data were extended. Finally, experiments confirm the effectiveness of our techniques under realistic settings.
