Edgar Frank Codd, (born August 19, 1923, Portland, Dorset, England—died April 18, 2003, Williams Island, Florida, U.S.), British-born American computer scientist and mathematician who devised the “ relational ” data model, which led to the creation of the relational database, a standard method of retrieving and storing computer data.

Edgar (Ted) Codd, the mathematician and former IBM Fellow best known for creating the “relational” model for representing data that led to today’s $12 billion database industry, died Friday, April 18, at his home in Florida at age 79.

Codd originally set out the rules in 1970, and developed them further in a 1974 conference paper. His aim was to prevent the vision of the original relational database from being diluted, as database vendors scrambled in the early 1980s to repackage existing products with a relational veneer.

Edgar Frank Codd (1923-2003) On August 23 , 1923 , English computer scientist Edgar Frank “Ted” Codd was born. His main achievement besides many contributions to computer science was the invention of the relational model for database management , the theoretical basis for relational databases .

Edgar F. Codd, a researcher at IBM, published a paper called “A Relational Model of Data for Large Shared Data Banks.” The paper was a rewrite of a paper he had circulated internally at IBM a year earlier. The paper is unassuming; Codd does not announce in his abstract that he has discovered a brilliant new approach to storing data.

Edgar Frank (Ted) Codd, the youngest of seven children, was born August 19th, 1923, on the Isle of Portland in the county of Dorset on the south coast of England. His father was a leather manufacturer and his mother a schoolteacher. During the 1930s he attended Poole Grammar School in Dorset.
