RELATIONAL DATABASE MODEL INVENTOR
The majority of large and small database are structured on the relational model, which is considered one of the greatest technological invenmtions of the 20th Century. E.F.CODD single-handedly is credited with developing and promoting that model in a series of research papers beginning with his 1969 IBM Research Report, "Derivability, Redudency, and Consistency of relations stored in Large Data Banks."
Edgar F.Codd began his career in 1949 when he joined IBM as a programming mathematician after graduating from Oxford University. Throughout the 1950s he helped develop several IBM computers and then turned his attention to database management. Among his achievements is earning the prestigious A.M.Turing Award, which is the Association for Computing Machinery's highest technical achievement honor given to an individual, for his relational database theory.
