| Abstract: | The moving objects DBMS based on OPDB was researched and designed. The system involved a data model, query language, database system for location-based service. Now, GIS was required to represent moving objects and to support querying on the motion properties of objects for location-based services. Such as advanced CRM applications may require to store and query the trajectories of mobile terminal users. But, the system design and processing motion-speclfic queries were challenging problem. A data model and data types for moving objects that includes complex evolving spatial structure and indeterminacy were defined, and then the system implementation was described. |
