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 research challenges faced by the System R team and how the technology they created has influenced the development of the modern database industry.
