System R: A relational data base management system [chapter]

Morton M. Astrahan, Donald D. Chamberlin, W. Frank King, Irving L. Traiger
1976 Lecture Notes in Computer Science  
INTRODUCTION System R is a data base management system which provides a high-level, non-procedural relational data interface.  ...  We wish to emphasize that System R is a vehicle for research in data base architecture, and is not available as a product.  ...  Fo Codd, originator of the relational model of data, and with L. Y. Liu, manager of the Computer Science Department of the IBM Research Laboratory.  ...

Access control in a relational data base management system by query modification

Michael Stonebraker, Eugene Wong
1974 Proceedings of the 1974 annual conference on - ACM 74  
The scheme can be applied to any relational data base management system and has several advantages over other suggested schemes.  ...  These include: a) implementation ease b) small execution time overhead c) powerful and flexible controls d) conceptual simplicity The basic idea utilized is that a user interaction with the data base is  ...  ACKNOWLEDGEMENT Research sponsored by the Naval Electronic Systems Command, Grant N00039-71-C-0255.and the Joint Services Electronics Program, Contract F44620-71-C-0087.  ...

Distributed query processing in a relational data base system

Robert Epstein, Michael Stonebraker, Eugene Wong
1978 Proceedings of the 1978 ACM SIGMOD international conference on management of data - SIGMOD '78  
In this paper we present a new algorithm for retrieving and updating data from a distributed relational data base.  ...  Within such. a data base, any number of relations can be distributed over' any number of sites.  ...  This algorithm is being implemented as part of the INGRES data base system.  ...

An authorization mechanism for a relational data base system

P. P. Griffiths, B. W. Wade
1976 Proceedings of the 1976 ACM SIGMOD international conference on Management of data - SIGMOD '76  
Examples of the techniques described are presented within the context of System R, a relational database system now under development.  ...  However, System R provides the ability to define views [2, 41 on top of base relations and on top of other views. The view mechanism is also the chosen method to grant selective access to a table.  ...

RankSQL: Supporting Ranking Queries in Relational Database Management Systems

Chengkai Li, Mohamed A. Soliman, Kevin Chen-Chuan Chang, Ihab F. Ilyas
2005 Very Large Data Bases Conference  
The increasing importance of top-k queries warrants an efficient support of ranking in the relational database management system (RDBMS) and has recently gained the attention of the research community.  ...  This imposes a big challenge to System-R style optimizers that build subplans in bottom-up fashion, because the input sizes consumed by operators depend on the location of that subplan in the complete  ...

A Mechanism for Managing the Buffer Pool in a Relational Database System Using the Hot Set Model

Giovanni Maria Sacco, Mario Schkolnick
1982 Very Large Data Bases Conference  
The design of the buffer manager in a Relational Database Management System can significantly affect the overall performance of the system.  ...  In this paper, we present a buffer management algorithm based on a model of database requests.  ...  However if that many frames are not available in the buffer IIn this paper, we use System R [ASTR76, BLAS79] as a model of a relational database management system.  ...

A Multi-Purpose Implementation of Mandatory Access Control in Relational Database Management Systems [chapter]

Walid Rjaibi, Paul Bird
2004 Proceedings 2004 VLDB Conference  
Mandatory Access Control (MAC) implementations in Relational Database Management Systems (RDBMS) have focused solely on Multilevel Security (MLS).  ...  The implication of this is that the investment of building an MLS RDBMS cannot be leveraged to serve the needs of application domains where there is a desire to control access to objects based on the label  ...  Michael Waidner, manager Network Security & Cryptography, for giving him the opportunity to start up the database security research activity at ZRL.  ...
