Abstract: . In this paper we are interested in storing and perform OLAP queries about various aggregate trajectory properties. We consider a data stream environment where a set of mobile objects send the data about its location in a irregular and unbounded way, the data volume is stored in a centralized and traditional DW with pre-computed aggregations values (preserving the trajectories privacy). We present an application developed to receive the stream data set, to store and compute the pre-aggregation values and to present final results in order to reveal the knowledge about the trajectories. 1.
