Abstract: There are mainly four kind of models to record and deal with historical information.Taking them as reference,the spatio-temporal model based on event semantic is proposed in this paper.In this model,according to the way describing an event,all the information are divided into five domains.This paper describes the model by using the land parcel change in the cadastral information system,and expounds the model by using five tables corresponding to the five domains.Based on this model,seven examples are given on historical query,rollback and recurrence.This model can be implemented either in the extended relational database or in the object-oriented database.
