In october 2013, we organised, with the GDD research group, the 29th BDA (Bases de Données Avancées) conference in Nantes, which is the main annual scientific meeting for the French research community in databases. The talks are available on video : keynotes, tutorials and standard sessions, through the conference website (most presentations are in French). Keynotes and tutorials include talks by Patrick Valduriez, Serge Abiteboul, Stratos Idreos, Stéphane Frénot and Stéphane Grumbach, on various aspects of “big data management” and personal data.
