Meaning of SQL

What is SQL?

SQL is the acronym for “Structured Query Language”, a standard language of data management that interacts with the main databases based on the relational model.

Some of the major systems that use SQL are: MySQL, Oracle, Firebird, Microsoft Access, PostgreSQL (open source), HSQLDB (open source and written in Java).
The SQL language emerged in 1974 and was developed in IBM Labs as an interface to the Relational Database Management System (RDBMS) called SYSTEM R. This system was created based on a 1970 article written by Edgar F. Codd.

Other languages ​​of the genre have emerged, but SQL has become the most widely used. The creation of a standard for SQL was performed in 1986 by the American National Standard Institute (ANSI) and in 1987 by the International Organization for Standards (ISO).

SQL is an essentially declarative language. This means that the programmer only needs to indicate what the intended purpose is for the RDBMS to execute.

Some of the key SQL commanding for data manipulation are: INSERT, SELECT, UPDATE, DELETE. SQL also enables the creation of relationships between tables and control of access to data.
