Event-based modeling for land management system in mining area

Both structural and behavioral aspects need to be modeled in some spatio-temporal databases. In this paper, an event-based approach is proposed for modeling the system's behavior of building reviewing. The spatio-temporal process is divided into three kind of components, that is agent, event and state, among them event is the key factor. All of the three components are taken into account while modeling the process, The relations among agent, event and state are analyzed, and special consideration is given to the event. Some problems for further investigations are also discussed in this paper.
