Welcome to the Data Systems Group
The Data Systems Group at the University of Waterloo's Cheriton School of Computer Science builds innovative, high-impact platforms, systems, and applications for processing, managing, analyzing, and searching the vast collections of data that are integral to modern information societies — colloquially known as "big data" technologies.
Our capabilities span the full spectrum from unstructured text collections to relational data, and everything in between including semi-structured sources such as time series, log data, graphs, and other data types. We work at multiple layers in the software stack, ranging from storage management and execution platforms to user-facing applications and studies of user behaviour.
Our research tackles all phases of the information lifecycle, from ingest and cleaning to inference and decision support.

One often-heard complaint is that academics labour away in their ivory towers, divorced from happenings in the real world. A few years ago, Professor Semih Salihoglu of the Data Systems Group at the University of Waterloo's Cheriton School of Computer Science noticed exactly this for graph processing.
