摘要：Both structural and behavioral aspects need to be modeled in some spatio-temporal databases. There existing initialefforts to represent behavioral aspects of the spatio-temporal applications via events gave their priority to some local orpartial behaviors rather than an overview of the system’s behavior. In this paper, an event-based approach is proposedfor modeling the system’s behavior of the spatio-temporal process of building reviewing. The relations between eventevent,event-state and state-state in the building reviewing process are analyzed. An event-flow diagram and a casualentity-relation diagram are developed for representing these relations. Event-based spatio-temporal queries arediscussed. The proposed approach has been used in developing the spatio-temporal databases of the computersupportedcollaborative building reviewing system in Changzhou municipality. Further investigation in this field includescausal modeling between agents and events, formal definition and specification of events and states, event-basedspatio-temporal data organization and query
