The ACM Special Interest Group on Management of Data is concerned with the principles, techniques and applications of database management systems and data management technology. Our members include software developers, academic and industrial researchers, practitioners, users, and students. SIGMOD sponsors the annual SIGMOD/PODS conference, one of the most important and selective in the field.
It is easy to join SIGMOD. You may become a SIGMOD member even if you are not a member of the ACM.
