Structured Query Language (SQL): An Introduction

Published: 17 February 2000

ID: G0090850

Analyst(s): Deborah A. Hess

Summary

SQL-- pronounced either "sequel" or "ess-queue-ell" is a declarative data manipulation language used with relational databases. It is a language-- not a database-- even though it is used only with databases. Furthermore, it is not a stand-alone language like Java or C++, but it can be embedded within a stand-alone language. It is implemented by nearly every relational database management system (RDBMS) vendor and can be used to create and maintain a database, modify data in the database, and retrieve data from a database.
