Spatiotemporal data model is one of the researching hotspots currently. The organization of real estate temporal data has also received extensive concern as the profession application of spatiotemporal data model. On the premise of analysis on spatial and temporal variations of the real estate data, this paper presents the idea that time attribute accedes to a record level. To solve the prob- lems of loading more than one attribute value for an attribute field in the relational data table, the study puts forward an effective solution.
