Colloquium Polaris - Pierre Senellart deciphers the construction of a management system base de données

We describe ProvSQL, software currently being developed in our team that adds support for provenance management to a regular database management system, PostgreSQL. We first explain what provenance is, applications thereof, and how provenance of database queries can be defined and captured. We insist on one particular application of provenance, probabilistic query evaluation. We then explain research and engineering challenges in implementing techniques from the scientific literature on provenance management and probabilistic databases within a major database management system.
Pierre Senellart is a Professor in the Computer Science Department at the École normale supérieure (ENS, PSL University) in Paris, France, and head of the Inria–CNRS–ENS Valda team. He is also a junior member of the Institut Universitaire de France and currently serves as the President of Section 6 of France's National Committee for Scientific Research.
