Donald Chamberlin, James Gray, Raymond Lorie, Gianfranco Putzolu, Patricia Selinger, Irving TraigerThe INGRES and System R systems demonstrated that a practical and efficient database management system (DBMS) could be implemented based on the relational data model. These systems were full-function DBMS's that supported non-procedural query languages (QUEL and SQL), automatic query optimization, alternative storage structures, transactions, crash recovery, views, integrity, and protection. They have revolutionized the database system industry by showing how data stored in a computer can be conveniently accessed by end users and while at the same time it can be used by production application programs.
