Model answer

SQL (Structured Query Language) is the standard language for working with relational databases. You use it to read data (SELECT), add (INSERT), change (UPDATE) and remove (DELETE) rows, and to define tables (CREATE, ALTER, DROP). Each database (PostgreSQL, MySQL, SQLite, SQL Server) adds its own extensions.
