25th International Database Engineering & Applications Symposium IDEAS 2021 Concordia University July 14 - 16, 2021, Montreal, Canada CALL FOR PAPERS/PARTICIPATION/TRACK PROPOSALS The annual IDEAS conference is a top international forum for data engineering researchers, practitioners, developers, and application users to explore revolutionary ideas and results, and to exchange techniques, tools, and experiences. We invite participation of all interested in this meeting which provides an insight into original research contributions relating to all aspects of database engineering defined broadly, and particularly topics of emerging interest describing work on integrating new technologies into products and applications, on experiences with existing and novel techniques, and on the identification of unsolved challenges. TRACK (TARGETED SESSION) As in the past, IDEAS 2021 will include tracks/targeted sessions on current topics of interest to the community. This year, we would be organizing several: some of which are proposed below. These special tracks/themes will form part of the program along with the main event: the following tracks are currently in place: Data Sharing, Security and Privacy, Bipin C. Desai, Software Engineering for Data Science, Juan J. Cuadrado-Gallego and Olga Ormandjieva. All paper submission for IDEAS’2021 would be via the corresponding pages on ConfSys. Authors should sign up as user of the system at: https://confsys.encs.concordia.ca/ConfSys/jsp/index.jsp TOPICS: A list of non-exhaustive topics can be found at: http://confsys.encs.concordia.ca/IDEAS/ideas21/ideas21_topics.php COVID-19: We are hoping that by the time of the IDEAS 2021 meeting, the vaccination program for Covid-19 would have ensured the ability of the participants to travel in security. To accommodate any issues, we would make arrangements to have an on-line option(as we have done for IDEAS2020, the last meeting). However, we are looking forward to a return to open skies and face-to-face meeting. IMPORTANT DATES April 23, 2021: EXTENDED Papers submission deadline: ++plus grace period May 31, 2021: Notification of acceptance June 27, 2021: Camera-ready deadline (Final Version of accepted submissions) When submitting a paper, pl. select the appropriate track unless you are submitting to the main event (indicated by "General Pool").
