The relational Model of Data is
based on the concept of a Relation. A Relation is a mathematical concept based
on the ideas of sets. The strength of the relational approach to data
management comes from the formal foundation provided by the theory of
relations. The model was first proposed by Dr. E.F. Codd of IBM in 1970 in the
following paper: "A Relational Model for Large Shared Data Banks," Communications
of the ACM, June 1970.
