I enjoyed reading this book, and would highly recommend it for others.
Tribal SQL has 15 chapters covering various topics relevant to DBA's. Each of the chapters has been written by a previously unpublished author, and all are based on their experiences. There are chapters covering most topics from Internals Data Compression, Performance tuning, Auditing and SQL Injection, through to less technical areas such as Reporting and Database Mail. Additionally, there are sections on personal skills which include Communication Skills, Project Management and an Introduction to Agile Database Development.
While some of the sections don't go into as much detail as you'd hope, this isn't the point of this book(from my understanding). It covers each of the areas well, leaves you interested for more, and most of the chapters include links to various sources for further reading.
It's also good to see the authors of this book donated their royalties to charity (Computers for Africa). Well done!
My only criticism is that I'd like to see an eBook/Kindle version of it so I can have it in the eBook library I have on my Tablet.
