What is the history of SQL?
The SQL programming language was first developed in the 1970s by IBM researchers Raymond Boyce and Donald Chamberlin. The programming language, known then as SEQUEL, was created following the publishing of Edgar Frank Todd’s paper, “A Relational Model of Data for Large Shared Data Banks,” in 1970.
