SQL
À propos de SQL
SQL is the abbreviation of “Structured Query Language” and refers to a domain-specific language used to communicate with data in a relational database management system.
SQL was developed in the 1970s by Donald Chamberlin and Raymond Boyce at IBM. Oracle developed the first commercialised version. MySQL, Oracle, Sybase, and MS SQL server are some examples of databases than use SQL.
Clauses, predicates, expressions, queries and statements are subdivided languages that structure SQL.
It belongs to the same family of languages as SEQUEL, QUEL and QBE.
