This demonstration shows an integrated query processing environment where users can seamlessly query both a data stream management system and a sensor network with one query expression. By integrating the two query processing systems, the optimization goals of the sensor network (primarily power) and server network (primarily latency and quality) can be unified into one quality of service metri...

In this paper, we demonstrate RecDB; a full-fledged database system that provides personalized recommendation to users. We implemented RecDB using an existing open source database system PostgreSQL, and we demonstrate the effectiveness of RecDB using two existing recommendation applications (1) Restaurant Recommendation, (2) Movie Recommendation.

All parent-offspring correlations are higher when the in...
