This work has involved a rich cross-fertilization between PDM and other disciplines in mathematics and computer science, including logic, complexity theory, and knowledge representation. We an- ticipate on-going expansion of PDM research as the technology and applications involving data management continue to grow and evolve. In particular, the lifecycle of Big Data Analytics raises a wealth of challenge areas that PDM can help with. In this report we identify some of the most important research directions where the PDM community has the potential to make significant contributions. This is done from three perspec- tives: potential practical relevance, results already obtained, and research questions that appear surmountable in the short and medium term.

Abiteboul et al. Dagstuhl Manifestos Schloss Dagstuhl – Leibniz-Zentrum für Informatik, Dagstuhl Publishing, Germany 2 Research directions for Principles of Data Management Executive Summary In April 2016, a community of researchers working in the area of Principles of Data Manage- ment (PDM) joined in the Dagstuhl Castle in Germany for a workshop organized jointly by the Executive Committee of the ACM Symposium on Principles of Database Systems (PODS) and the Council of the International Conference on Database Theory (ICDT). The mission of this workshop was to identify and explore some of the most important research directions that have high relevance to society and to Computer Science today, and where the PDM community has the potential to make significant contributions. This report describes the family of research directions that the workshop focused on from three perspectives: potential practical relevance, results already obtained, and research questions that appear surmountable in the short and medium term. This report organizes the identified research challenges for PDM around seven core themes, namely Query Processing at Scale, Multi-model Data, Uncertain Information, Knowledge-enriched Data, Data Management and Machine Learning, Process and Data, and Ethics and Data Management. Since new challenges in PDM arise all the time, we note that this list of themes is not intended to be exhaustive. This report is intended for a diverse audience. It is intended for government and industry funding agencies, because it includes an articulation of important areas where the PDM community is already contributing to the key data management challenges in our era, and has the potential to contribute much more. It is intended for universities and colleges world-wide, because it articulates the importance of continued research and education in the foundational elements of data management, and it highlights growth areas for Computer Science and Management of Information Science research. It is intended for researchers and students, because it identifies emerging, exciting research challenges in the PDM area, all of which have very timely practical relevance. It is also intended for policy makers, sociologists, and philosophers, because it re-iterates the importance of considering ethics in many aspects of data creation, access, and usage, and suggests how research can help to find new ways for maximizing the benefits of massive data while nevertheless safeguarding the privacy and integrity of citizens and societies.
