The Data Systems Seminar Series provides a forum for exploring and discussing important topics in data systems, from current challenges to emerging trends. It complements our internal meetings by bringing fresh perspectives from invited external speakers.
The schedule for the 2026–27 academic year is outlined below and will be updated as speakers are confirmed.
Seminars are typically held monthly on Mondays at 10:30 a.m. in DC 1302, unless otherwise noted. Some sessions may be held virtually on Zoom; these will be clearly marked.
All talks are open to the public.
We will record and upload videos of presentations whenever possible. Past DSG Seminar Series videos are on the DSG YouTube channel.

| Title | Beyond Sets and Bags — The Behavioral Perspective in Data Management |
| Speaker | Matthias Weidlich, Hasso Plattner Institute, University of Potsdam |
| Abstract | In various application scenarios, the temporal perspective of data is of particular importance. That is, the ordering of data elements constitutes an essential aspect in their analysis, for instance, by identifying behavioral patterns in a dataset. In this talk, I give an overview of some of our work on answering the questions of why to query for certain behavior, how to support users in the definition of effective queries, and how to evaluate these queries efficiently. |
