Structured Query Language

SQL (Structured Query Language) is a computer language aimed to store, manipulate, and retrieve data stored in relational databases. The first incarnation of SQL appeared in 1974, when a group in IBM developed the first prototype of a relational database. The first commercial relational database was released by Relational Software (later becoming Oracle).
