SQL“ Structured Query Language ”

Introduction to SQL “ Structured Query Language ”

• SQL is the common language, that lies in the heart of every RDMS.

• SQL is the language “ very focused language ”.

• SQL is a declarative query language not a procedural language,

what it means that you use SQL to describe what you want

and let the RDMS handle how that actually done.
