The series of ICDT conferences (https://databasetheory.org/icdt-pages) provides an international forum for the communication of research advances on the theoretical foundations of database systems.
The 20th edition of ICDT will take place in Venice, Italy between the 21st and the 24th of March 2017 (http://edbticdt2017.unive.it).
ICDT has now two submission cycles with the next one closing on Sep. 11th, 2016 (abstract) and Sep. 18th, 2016 (full papers).
The first round of reviews has now been completed and the list of accepted research papers is:
