Oracle 10G and DB2 are acknowledged as industry leaders in the database field and both are strong in terms of features and are surprisingly easy to use with clean GUIs.
However, one of the other databases tested is also acknowledged by the industry and has proven itself in terms of reliability and performance in many very large installations around the globe. And what's more it is free!
Release 5.0 of MySQL is really taking it to the Oracle and DB2 with advanced features such as cluster support and fault tolerance and in most other departments the features run head to head with the competition. Non-SQL junkies can take heart with the GUIs dramatically reducing the reliance on the CLI, bringing administration and configuration within the realms of the novice. MySQL V5.0 is a compelling product and it is hard to argue against its nomination for the Editor's Choice award.
