Origin of SQL | Oracle SQL fundamentals

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.
Since then, the American National Standards Institute (#ANSI) and the International Standards #Organization have deemed the SQL language the standard language in relational #database communication. While major SQL vendors do modify the language to their desires, most base their SQL programs off of the ANSI approved version.
