摘要：The paper proposes an object-oriented spatio-temporal data model based on space-time composite by taking advantage of high topological representation ability of the space-time composite data model and investigating the key concepts and technologies of object-oriented method. Then, the paper describes how to structure and manipulate spatio-temporal data. The spatio-temporal data model introduced in this literature can explicitly represent topology change of spatial entities over time dimension and quickly restore the topological information at specific time point. It's proved that the spatio-temporal data model can save storage, reduce data redundancy, accelerate responding speed and expand the functions of spatio-temporal queries and analyses
