Relational model
The relational model for management of a database is a data model based on predicate logic and set theory.
History
The relational model was invented by Dr. Ted Codd as a general model of data, and subsequently maintained and developed by Chris Date and Hugh Darwen among others. In The Third Manifesto (1995) they show how the relational model can be extended with object-oriented features without compromising its fundamental principles.
