A preface: as it usually happens with my favorite topic, neither database conferences, nor software engineering conference acknowledge that kind of research. Thereby, when although the paper got accepted, it was accepted as a short paper (because nobody understood what it was about :)).
Moreover, two days before the conference we were asked to shorten the presentation to 15 minutes. Fortunately for me, there was one no-show at our session, so I was able to present in full. Below is a full presentation version including two slides which were not in today’s presentation.
