- This paper proposes a moving objects data model, query language, main memory database system for location-based service. Location-based services require GIS databases system to represent moving objects and to support querying on the motion properties of objects. For example, fleet management applications may require storage of information about moving vehicles. Also, advanced CRM applications may require to store and query the trajectories of mobile phone users. But, modeling consistent information about the location of continuously moving objects and processing motion-specific queries is challenging problem. We formally define a data model and data types for moving objects that includes complex evolving spatial structure and indeterminacy, and then describe the system implementation. © Springer-Verlag Berlin Heidelberg 2004.
