Edgar F. Codd idézet

Edgar Frank Ted Codd angol matematikus, informatikus, aki hozzájárult a relációs adatbázisok elméletének kialakításához. Az IBM kutatójaként létrehozta az adatbázis-kezelő rendszerek részére a relációs adatmodellt. Az informatikához kapcsolódó további értékes felfedezései is voltak, de az adatbázis-kezelés elméletéhez született adatmodell volt legemlékezetesebb felfedezése. Wikipedia

Relational Database: A Practical Foundation for Productivity (1982)

“The adverse impact on development productivity of requiring programmers to navigate along access paths to reach target data […] was enormous. In addition, it was not possible to make slight changes in the layout in storage without simultaneously having to revise all programs that relied on the previous structure. […] As a result, far too much manpower was being invested in continual (and avoidable) maintenance of application programs.”

“Relational processing entails treating whole relationships as operands. Its primary purpose is loop-avoidance, an absolute requirement for end users to be productive at all, and a clear productivity booster for application programmers.”
