Ensuring the Reliability and Robustness of Database Management Systems (Dagstuhl Seminar 23441)

The goal of this Dagstuhl Seminar was to bring together researchers and practitioners interested and experienced in database systems and the reliability aspects thereof. It is a continuation of a previous seminar on this topic, which had built an initial understanding of the challenges and areas of future work. In this edition of the seminar, we aimed for a tangible outcome of the seminar by writing a manuscript documenting the (1) best practices in ensuring database systems' reliability, (2) the state of the art on this topic in research, as well as (3) open challenges, which might also serve as the cornerstone of writing a book on this topic presented in this report. We achieved this by forming four primary working groups during the seminar, namely (1) on the automated testing aspects concerning analytical components of database systems, (2) benchmarking, (3) reliability for transaction and concurrency aspects, as well as (4) query languages and debugging. The report contains four sections presenting the results of these working groups. Some of these working groups and individuals plan to further refine their work and discussion outcomes, aiming to submit them to upcoming venues.
