The relational data model, proposed by E.F. Codd in 1970, inspired several research projects at IBM and elsewhere. Among these was System R, which demonstrated the commercial viability of relational database systems. This article describes the resear

We have described the architecture of System R, including the Relational Data System and the Research Storage System. The RDS supports a flexible spectrum of binding times, ranging from precompilation of “canned transactions” to on-line execution

To improve performance of repetitive transactions in System R, IBM's Raymond Lorie devised a scheme to create, save, and reuse a generalized access plan that could be instantiated with specific values. The author recounts his role in compiling such g

This study compared the effects of metallic, nonmetallic, and sonic instrumentation on titanium abutment surfaces in vitro. Designated test surfaces in each of seven abutments were instrumented either for 25 strokes or 30 seconds, and for 50 strokes

System R, an experimental database system, was constructed to demonstrate that the usability advantages of the relational data model can be realized in a system with the complete function and high performance required for everyday production use. Thi

System R is a database management system which provides a high level relational data interface. The systems provides a high level of data independence by isolating the end user as much as possible from underlying storage structures. The system permit

A multiuser database system must selectively permit users to share data, while retaining the ability to restrict data access. There must be a mechanism to provide protection and security, permitting information to be accessed only by properly authori
