SQL Definition

Stands for “Structured Query Language,” and can be pronounced as either “sequel” or “S-Q-L.” It is a query language used for accessing and modifying information in a database. Some common SQL commands include “insert,” “update,” and “delete.” The language was first created by IBM in 1975 and was called SEQUEL for “Structured English Query Language.” Since then, it has undergone a number of changes, many coming from Oracle products.

Today, SQL is commonly used for Web database development and management. Though SQL is now considered to be a standard language, there are still a number of variations of it, such as mSQL and mySQL. By using a scripting language likeĀ PHP, SQL commands can be executed when a Web page loads. This makes it possible to create dynamic Web pages that can display different information each time they load.
