Join Dependency Testing, Loomis-Whitney Join, and Triangle Enumeration
In this paper, we revisit two fundamental problems in database theory. The first one is called join dependency (JD) testing, where we are given a relation r and a JD, and need to...

Querying Big Data by Accessing Small Data
This paper investigates the feasibility of querying big data by accessing a bounded amount of the data. We study boundedly evaluable queries under a form of access constraints, wh...

External Memory Stream Sampling
This paper aims to understand the I/O-complexity of maintaining a big sample set—whose size exceeds the internal memory’s capacity—on a data stream. We study this topic in a...

Skyline Queries with Noisy Comparisons
We study in this paper the computation of skyline queries - a popular tool for multicriteria data analysis - in the presence of noisy input. Motivated by crowdsourcing application...
