For the past many years, the MySQL® Relational Database Management System has
been the most widely adopted Open Source database system in the world. With the
release of MySQL version 5.0, adoption of MySQL into the enterprise sector of
companies is certain to grow even faster than ever before.
When the first
edition of the MySQL Certification Study Guide was published in April
2004, we noted how MySQL adoption had grown to an estimated 4 million
installations. At the time of writing, that estimate has risen to more than 8
million - and by the time you read this, who knows?
With that kind of adoption rate, the need for qualified personnel to write
applications for, and to manage, MySQL installations increases dramatically. Not
only will many more companies be moving to MySQL; many companies that already
employ MySQL will be using it in larger and larger parts of their organizations,
perhaps to support new functionality, perhaps to replace legacy systems.
Whether you are new to MySQL certification, know a little bit about it, or
already hold the Core or Professional certification titles, you should know that
many changes are taking place in the transition from the version 4.0/4.1 exams
to the version 5.0 exams.
