Introduction

Released in January 1998, MySQL is an open source relational database management system (RDBMS). It's based around the Structured Query Language (SQL), and is best for managing the content of the database as opposed to transactions, as MySQL does not support COMMIT or ROLLBACK. One of the biggest drawbacks of MySQL is it's lack of support for referential integrity, no stored procedures, no triggers, and no sub-queries. MySQL is free, and may be downloaded from download section at MySQL.
