Synopsis "Pods '19: Proceedings of the 38Th acm Sigmod-Sigact-Sigai Symposium on Principles of Database Systems"
It is our great pleasure to welcome you to the 38th ACM SIGMOD-SIGACT-SIGAI Symposiumon Principles of Database Systems (PODS 2019), held in Amsterdam, The Netherlands, on July 1-3, 2019, in conjunction with the 2019 ACM SIGMOD International Conference on Managementof Data.Since the first edition of the symposium in 1982, the PODS papers are distinguished by arigorous approach to widely diverse problems in data management, often bringing to beartechniques from a variety of different areas, including computational logic, finite model theory, computational complexity, algorithm design and analysis, programming languages, and artificialintelligence.The PODS Symposia study data management challenges in a variety of application contexts, including more recently parallel computation, streaming and realtime data, and graph dataprocessing algorithms. PODS has a tradition of being the premier international conference onthe theoretical and foundational aspects of data management, and the interested reader isreferred to the web page https: //databasetheory.org/pods for information on the history of thisconference series.This year's symposium continues this tradition and invited for submission papers providingoriginal, substantial contributions in one or more of the following categories: a) deep theoretical exploration of topical areas central to data management;b) new formal frameworks that aim at providing a basis for deeper theoretical investigation ofimportant emerging issues in data management; andc) validation of theoretical approaches from the lens of practical applicability in datamanagement. Papers in this track should provide an experimental evaluation that gives newinsight in established theories. Besides, they should provide a clear message to the databasetheory community as to which aspects need further (theoretical) investigation, based on theexperimental findings. As in previous years, PODS operated with two submission cycles. The first cycle allowed for thepossibility for papers to be revised and resubmitted. For the first cycle, 36 papers weresubmitted, 4 of which were directly selected for inclusion in the proceedings, and 8 were invitedfor a resubmission after a revision. The quality of the revised papers increased substantially withrespect to the first submission, and all of the revised papers were selected for the proceedings.For the second cycle, 51 papers were submitted, 17 of which were selected, resulting in 29 papersselected overall from a total number of 87 submissions.This volume contains the proceedings of PODS 2019, which include papers on the keynoteaddressed by Cynthia Dwork of Harvard University, the two invited tutorials, one of the twoGems talks, and 29 contributions that were selected by the Program Committee for presentationat the symposium.
