The letters SQL stands for Structured Query Language. It is a special purpose programming language created for handling data in RDBMS or Relational Database Management System. It is originally based on tuple relational calculus and relational algebra and is composed of a data manipulation language and a data definition language.
It is the standard language used for manipulating and accessing data in databases. It is one of the first languages circulated commercially and became the standard of ANSI or the American National Standards Institute in 1986 and also of ISO or the International Organization for Standards in 1987. The program during those times is not entirely portable among other database systems that might lead to vendor lock-in.
SQL was first created by Raymond F. Boyce and Donald D. Chamberlin at IBM in early 1970s. They first called it SEQUEL or Structured English Query Language. It was first intended to control and get data stored in System R, which is IBM’s first quasi-relational database management system. System R was developed by a group in the 1970s at IBM San Jose Research Laboratory.
