The MySQL Tutorial consists of a series of short, very concise chapters, each on a tightly targeted topic, with a task-oriented focus. Each chapter is written so it can be read in a single sitting and be easily digested. The main focus is on five key areas: installation and configuration, using MySQL, administering MySQL, optimizing MySQL, and MySQL's associated APIs. With 4 million installations and 27,000 downloads per day, MySQL continues to grow as one of the most widely used databases in the world. Now an enterprise-level database, MySQL features full support for transactions, integrating improvements that enhance MySQL's architectural foundation for building heavy-load commercial applications.
