SQL – Structured Query Language

The SQL Standard
SQL – Structured Query Language
A ‘standard’ that specifies how

  • a relational schema is created
  • data is inserted / updated in the relations
  • data is queried
  • transactions are started and stopped
  • programs access data in the relations
  • and a host of other things are done


Every relational database management system (RDBMS) is required to support /
implement the SQL standard.
