Pioneers whose defining contribution is organizing collections of data so they can be stored, queried, updated and kept consistent at scale, the ACM Computing Classification System's Information Systems area (this atlas's prior pioneer field of the same subject was titled Databases; the people and the subject are unchanged). Edgar F. Codd's 1970 relational model, Charles Bachman's Integrated Data Store and network data model, Christopher J. Date's relational theory, Michael Stonebraker's relational database systems and Peter Chen's entity relationship model. Does not belong here: a pioneer whose defining work is a general purpose programming language that happens to be used against a database, filed under Software and Its Engineering instead.
