The INGRES protection system
Michael R Stonebraker, Peter Rubinstein · 1976
This paper presents the design of a protection system being implemented for the INGRES relational data base management system. A brief description of the INGRES system and its operational environment is first presented to provide the setting for the protection scheme. Mechanisms for protecting physical data files and enforcing sophisticated access control rules for shared relations are then presented. Lastly, the important design decisions concerning protection are discussed.
