If you are a developer or DBA who is new to DB2, I would highly recommend this book to you. Both administration and development topics are covered, helpful best practices and tips are included, and illustrative examples are used.
The fundamental DB2 concepts and the different DB2 tools such as the Control Center are introduced in a very straightforward and easy-to-understand manner. This allows DB2-newbies to get fully up to speed on DB2 terminology and functionality, while serving as a gentle refresher for those who might have prior DB2 experience. The book achieves a good balance of topic selection and level of detail. More advance topics that are covered are explained in a manner that most novices would comprehend and in enough detail to be useful.
