The data management landscape has continued to rapidly diversify in the past few years. While the relational database (RDB) model continues to play a leading role, the challenges and opportunities evoked by modern data management call for new lines of thinking regarding models and computational solutions that go beyond traditional RDBs. Complex challenges for database research stem, in particular, from emerging requirements in machine learning, representations of uncertain data and knowledge, explainable AI, and data science in general.

The focus of the DBAI seminar will be on discussing these novel challenges – and the current and possible future approaches to address them – with the goal of identifying open questions and key opportunities for research at the intersection of data management and A.I.


The seminar is by invite only and will be held in Hotel Santa Cruz, November 12–15, 2019, in the Colchagua valley close to Santiago de Chile.

Accomodation in the hotel will be provided, as will transport to and from Santiago. Attendees are expected to fund other costs such as flights, accomodation before/after in Santiago, etc.

The city of Santa Cruz is 180 kms. and 2.5 hrs. by car south from Santiago. There will be buses leaving from downtown Santiago and Santiago airport to Santa Cruz on the morning of November 12, and going back to Santiago in the late afternoon of November 15. More logistic details will follow shortly.
