Query: Research Directions for Principles of Data Management (Dagstuhl
  Perspectives Workshop 16151)   In April 2016, a community of researchers working in the area of Principles
of Data Management (PDM) joined in a workshop at the Dagstuhl Castle in
Germany. The workshop was 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.
