Overview
Structured Query Language (SQL) is a special-purpose programming language designed for
managing data held in a Relational Database Management System (RDBMS). SQL-like languages
can also be used in Relational Data Stream Management Systems (RDSMS), or in "not-only SQL"
(NoSQL) databases.
SQL comprises of 3 major sub-languages:
1. Data Definition Language (DDL): to create and modify the structure of the database;
2. Data Manipulation Language (DML): to perform Read, Insert, Update and Delete operations
