SCALABLE SCHEDULING OF UPDATES IN STREAMING DATA WAREHOUSES

SCALABLE SCHEDULING OF UPDATES IN STREAMING DATA WAREHOUSES We discuss update scheduling in streaming data warehouses, which combine the features of traditional data warehouses and data stream systems. In our setting, external sources push append-only data streams into the warehouse with a wide range of interarrival times. While traditional data warehouses are typically refreshed during […]


EFFICIENT COMPUTATION OF RANGE AGGREGATES AGAINST UNCERTAIN LOCATION-BASED QUERIES

EFFICIENT COMPUTATION OF RANGE AGGREGATES AGAINST UNCERTAIN LOCATION-BASED QUERIES In many applications, including location-based services, queries may not be precise. In this paper, we study the problem of efficiently computing range aggregates in a multidimensional space when the query location is uncertain. Specifically, for a query point Q whose location is uncertain and a set […]
