Relational database system

Any relational database would also be suitable. We've selected MySQL for the database examples in this book, as it's one of the most popular open source databases widely used in thousands of successful data-intensive applications.

However, if you prefer to use your own database server, you can, as long as it's JDBC compliant. However, in that case, you'll have to figure the own configurations required for the examples yourself, as we've used MySQL as the default database server for all the examples in this book.
