| Abstract: | Spatio-temporal databases model and query are used for moving objects, whose position and/or extent are changing over time. In this paper,the authors present the main aspects of spatiotemporal data types of moving objects and extended data types. And useful spatio-temporal operators are also introduced simply based on the data types. Such data model can be implemented easily,and it also supports spatio-temporal query well. |
