  • This work describes the features of the DOMINO (Database fOr MovINg Objects) system, which brings several novelties to the problem of managing moving objects databases. Our robust model of a trajectory captures the inherent parameter of uncertainty of the moving objects location, which impacts both the semantics of spatio - temporal queries and the algorithms for their processing. In DOMINO, we present a set of novel operators which capture the spatial, temporal and uncertainty aspects of a moving object. The operators are implemented as UDFs (User Defined Functions) on top of existing ORDBMS and can be used for answering queries and generating notification triggers. DOMINO's implementation, in which ORDBMS are coupled with other systems, seamlessly integrates several technologies: 1. existing electronic maps are used to generate the trajectory plan on behalf of a mobile user; 2. real-time traffic sources are used to automatically update the moving object's trajectories; 3. powerful (web-browser) GUI enables users to monitor and pose queries about objects.
