SEBD 2023

The thirty-first edition of the Italian Symposium on Advanced Database Systems (SEBD - Sistemi Evoluti per Basi di Dati) is organized by the Intelligent Interactive Information Access Hub of the Department of Information Engineering of the University of Padua, and will take place in Galzignano Terme (Italy) from the 2nd of July to the 5th of July 2023.

The symposium is the major annual event of the Italian database research community at large (English is the official language of the conference). The symposium is thought of as a gathering forum to meet, discuss and exchange experiences among all those, both in the academy and industry, who are interested in database systems and in all their broad range of applications.

SEBD 2023 is a single-track conference.

SEBD 2023 invites two kinds of contributions: full papers (up to 12 pages) and discussion papers (up to 8 pages).

The award

SEBD (Symposium on Advanced Database System) is the major annual event of the Italian database research community. It is thought of as a gathering forum to meet, discuss, and exchange experiences among all people from academia and industry who are interested in database systems and in all their broad range of applications.

SEBD 2022 marked the 30th edition, a remarkable achievement, representing a tangible trace of the scientific contributions of the Italian database community, its evolution over a long period of time, and its liveliness. To celebrate this achievement, SEBD 2022 introduced the “Taste of Time” Award (TTA) whose purpose is to recognize seminal contributions and to retrace the history of the Italian database community by selecting significant (AND TASTY 😁) papers from past editions of SEBD.

SEBD 2023 continues this brand new tradition and calls for nominations for the TTA 2023!

The ultimate goal of the TTA is to keep the tradition of the SEBD community alive, to contextualize the most important research lines and make sense of their evolution, and to inspire new generations of researchers by discussing how key challenges have been addressed, which ones are still open, and what can follow-up from them.

The SEBD Steering Committee will select papers based on the following impact criteria

  • impact within (a subarea of) the database research community
  • impact outside of the database research community
  • impact on the non-research community

Papers eligible for the TTA are either original research published at SEBD or extended abstracts of papers published in main venues for the database community. In both cases evidence about the impact of the paper (or related paper, in case of extended abstracts) has to be provided, e.g., follow-up works (papers, systems, …), new theories and models, social and/or industrial impact, citations, … The TTA will consider, each year, a scrolling window of 3 years, starting from the first SEBD 1993, from which to select papers for the TTA.

The SEBD community is very welcome to nominate papers deemed deserving of the TTA. Eligible papers for this round are those published in:

User-Defined Functions in Relational Databases: Challenges and Promising Solutions based on YeSQL

Monday, 3 July 2023


The diversity and complexity of modern data management applications have led to the extension of the relational paradigm with syntactic and semantic support for User-Defined Functions (UDFs). Although well-established in traditional DBMS settings, UDFs have become central in many application contexts as well, such as data science, data analytics, and edge computing. Still, a critical limitation of UDFs is the impedance mismatch between their evaluation and relational processing.

In this talk, I will first give an overview of the area and the technical challenges that UDF processing brings. I will then present YeSQL, an SQL extension with rich UDF support along with a pluggable architecture to easily integrate it with either server-based or embedded database engines. YeSQL currently supports Python UDFs fully integrated with relational queries as scalar, aggregator, or table functions. Key novel characteristics of YeSQL include easy implementation of complex algorithms and several performance enhancements, including tracing JIT compilation of Python UDFs, parallelism and fusion of UDFs, stateful UDFs, and seamless integration with a database engine. Experimental analysis showcases the usability and expressiveness of YeSQL and demonstrates that its techniques of minimizing context switching between the relational engine and the Python VM are very effective and achieve significant speedups of up to 68x in common, practical use cases compared to earlier approaches and alternative implementation choices.

Responsible Data Management

Tuesday, 4 July 2023


Incorporating ethics and legal compliance into data-driven algorithmic systems has been attracting significant attention from the computing research community, most notably under the umbrella of fair and interpretable machine learning. Yet, much of this work has been limited to the "last mile" of data analysis, disregarding both the data lifecycle, and the lifecycle of a system's design, development, and use. In my talk, I will argue that the decisions we make during data collection and preparation profoundly impact the robustness, fairness and interpretability of the systems we build, and that our responsibility for the operation of these systems does not stop once they are deployed. I will discuss technical work, and will place this work into the broader context of policy, education, and public outreach.

Short Bio

Dr. Julia Stoyanovich is Institute Associate Professor of Computer Science and Engineering, Associate Professor of Data Science, and Director of the Center for Responsible AI at New York University. Her goal is to make “Responsible AI” synonymous with “AI”. She works towards this goal by engaging in academic research, education and technology regulation, and by speaking about the benefits and harms of AI to practitioners and members of the public. Julia’s research interests include AI ethics and legal compliance, data management and AI systems, and computational social choice. She has co-authored over 100 academic publications, and has written for the New York Times, the Wall Street Journal, and Le Monde. Julia has been teaching courses on responsible data science and AI to students, practitioners and the general public. She is a co-author of the “Data, Responsibly” and “We are AI” comic book series. She received her M.S. and Ph.D. degrees in Computer Science from Columbia University, and a B.S. in Computer Science and in Mathematics & Statistics from UMass Amherst. Julia’s work has been generously supported by the US National Science Foundation, Pivotal Ventures, JP Morgan Chase, and Meta Responsible AI, among others. She is a recipient of an NSF CAREER award and a Senior Member of the ACM.
