SQL

This article or section is in need of expansion. Please add further information.

SQL, which stands for Structured Query Language, is a programming language designed for accessing and managing information contained in relational databases.

SQL commands can be divided into two groups: DDL (Data Definition Language) statements allow users to create and modify tables and database structures, while DML (Data Manipulation Language) statements are used to manage the data stored within those tables.

Traditionally, practically every nontrivial Web site employed some form of SQL for maintaining databases, although some massive enterprises with complex data-mining needs (such as Twitter and Facebook) have begun to adopt "NoSQL" database systems that store data in slightly different ways.

Microsoft's SQL Server, Oracle, and the open-source MySQL are three of the most popular and widely-used SQL solutions in use today. MFGG's forums and mainsite are supported by MySQL.
