A Spatiotemporal Model and Language for Moving Objects on Road Networks
Moving object databases are becoming more popular due to the increasing number of application domains that deal with moving entities and need to pose queries. So far implementations of such systems have been rather weak and certainly not at industrial strength level. In this paper we define a concise data model and a set of powerful query predicates for moving objects. Moreover, we propose an implementation design based on off-the-shelf industrial solutions enhancing thus the applicability and robustness of our approach.
