Object-oriented spatial data model better describes geographic phenomena. Due to lack of complete object-oriented database management system presently, it’s essential to study further object-oriented data-model construction under RDBMS and Object-relation GIS. Based on theories of Model Driven Architecture, this paper studies the approach and technology methods of constructing spatio-temporal data model by event-driven, which bases on RDBMS and Object-relation GIS. Firstly, a theoretical model of constructing object-oriented data model is built. Secondly, the definition and arrangement method of events and objects with the application of urban public traffic is studied. Thirdly, the object-oriented dynamic behavior model, temporal behavior model and software mode are constructed, and the executable ability of the models are validated. This paper gives a new approach in inter-perform among different frameworks and systems by applying Model Driven Architecture and event-driven method to build an object-oriented spatio-temporal model.
