SQL

SQL (Structured Query Language, pronounced “S-Q-L” or sometimes “Sequel”) is a standardized database language specifically used for managing and manipulating relational databases. Through SQL, users can create, retrieve, update, and delete data, as well as design and manage database structures.

A Relational Database Management System (RDBMS) is a type of database system where data is stored in structured tables with rows and columns, facilitating complex queries and transactions. Popular open source examples include MySQL and PostgreSQL.
