The Principles of Database Systems (PODS) symposium series, held in conjunction with the SIGMOD conference series, provides a premier annual forum for the communication of new advances in the theoretical foundations of data management, traditional or nontraditional. The symposium aims to provide a solid scientific basis for methods, techniques, and solutions for the data management challenges that continually arise in our data-driven society. It seeks scientific articles that present principled contributions to modeling, application, and system building in the context of data management, establishing theoretical results, developing new concepts, providing experimental work, or analyzing important industry artifacts.
