The annual '''ACM SIGMOD Conference''', which began in 1975, is considered one of the most important in the field,{{Cite web |title=csconference |url=https://csconferences.org/#SIGMOD}} and received an A* ranking over all edition of the CORE Conference Ranking system.{{Cite web |title=CORE Conference Ranking |url=https://portal.core.edu.au/conf-ranks/56/}} While traditionally this conference had always been held within North America, it took place in Paris in 2004, Beijing in 2007, Athens in 2011, Melbourne in 2015, Amsterdam in 2019, Santiago de Chile in 2024 and Berlin in 2025. The acceptance rate of the ACM SIGMOD Conference, averaged from 1996 to 2012, was 18%, and it was 17% in 2012.{{ cite web | url=http://dl.acm.org/citation.cfm?id=2213836&picked=prox | year=2012 | title=Proceedings of the 2012 ACM SIGMOD International Conference on Management of Data | access-date=2012-09-17 }} Important publications of database systems appear first at SIGMOD, for example, the [PostgreSQL](/source/PostgreSQL) database system created by [Michael Stonebraker](/source/Michael_Stonebraker) was presented in 1986,{{Cite web |title=The design of POSTGRES |url=https://dl.acm.org/doi/10.1145/16894.16888}} for which he received the [ACM Turing Award](/source/ACM_Turing_Award) in 2014.{{Cite web |title=Michael Stonebraker |url=https://amturing.acm.org/award_winners/stonebraker_1172121.cfm}} In association with [SIGACT](/source/SIGACT) and [SIGAI](/source/SIGAI), SIGMOD also sponsors the annual ACM [Symposium on Principles of Database Systems](/source/Symposium_on_Principles_of_Database_Systems) (PODS) conference on the theoretical aspects of database systems. PODS began in 1982, and has been held jointly with the SIGMOD conference since 1991.{{Cite web |title=PODS {{!}} PRINCIPLES of DATA MANAGEMENT -- databasetheory.org |url=https://databasetheory.org/PODS |access-date=2023-05-02 |website=databasetheory.org}} Each year, the group gives out several awards to contributions to the field of data management. The most important of these is the [SIGMOD Edgar F. Codd Innovations Award](/source/SIGMOD_Edgar_F._Codd_Innovations_Award) (named after the computer scientist [Edgar F. Codd](/source/Edgar_F._Codd)), which is awarded to "innovative and highly significant contributions of enduring value to the development, understanding, or use of database systems and databases". Additionally, SIGMOD presents a Best Paper Award{{cite web | url=http://jeffhuang.com/best_paper_awards.html#sigmod | title=SIGMOD Conference Best Paper Awards | access-date=2012-04-07 }} to recognize the highest quality paper at each conference, and [Jim Gray](/source/Jim_Gray_(computer_scientist)) Dissertation Award to the best Ph.D. thesis in data management. Initially, SIGMOD offered one submission cycle per year, a frequency that increased stepwise to four rounds by 2024. Until 2022, papers from accepted submissions were published in subsequent proceedings. From 2023 onwards, the publication model changed to a rolling release similar to a journal.{{Cite web |title=Proceedings of the ACM on Management of Data |url=https://dblp.org/db/journals/pacmmod/}} == Symposium on Principles of Database Systems (PODS) == {{Infobox academic conference | title = Symposium on Principles of Database System | history = 1982–present | frequency = Annual | discipline = [Database theory](/source/Database_theory) | abbreviation = PODS | publisher = [ACM](/source/Association_for_Computing_Machinery) | country= International | openaccess = no | website = https://sigmod.org/pods-home/ }} The '''ACM Symposium on Principles of Database Systems''' ('''PODS''') is an international research conference on [database theory](/source/database_theory), and has been held yearly since 1982. It is sponsored by three [Association for Computing Machinery](/source/Association_for_Computing_Machinery) SIGs, [SIGAI](/source/SIGAI), [SIGACT](/source/SIGACT), and [SIGMOD](/source/SIGMOD). Since 1991, PODS has been held jointly with the [ACM SIGMOD Conference](/source/ACM_SIGMOD_Conference), a research conference on systems aspects of data management. PODS is regarded as one of the top conferences in the area of database theory and data algorithms. It holds the highest rating of A* in the CORE2021 ranking{{Cite web |title=CORE ranking |url=http://portal.core.edu.au/conf-ranks/46/}}. The conference typically accepts between 20 and 40 papers each year, with acceptance rates fluctuating between 25% and 35%. ==Venues of SIGMOD/PODS conferences== {| class="wikitable sortable" |- !
