: Simplifying data programming is a core mission of data management research. The issue at stake is to help engineers build efficient and robust data-centric applications. The fron...
We present our prototype system, OMCAT, which optimizes the reevaluation of a set of pending continuous spatio-temporal queries on trajectory data, when some of the trajectories a...
