In 2013, ICDT started to give a Test-of-time Award for the paper (or a small number of papers) that has had a significant impact in terms of research, methodology, conceptual contribution, or transfer to practice since it appeared in the proceedings of ICDT. In years with odd numbers and from 2020 on in all years, it is given to the best such paper of the ICDT conference that took place ten years ago. However, in 2014, 2016, and 2018 it will be given to papers that appeared before 2003 as detailed in the table below.
