Although the book is considerably outdated (published in 2001) and it makes reference to a very old version of Oracle Database Manager (Oracle 8i), I found it really useful, because many of the advices and features are still present in the newer versions.
There was some interesting stuff here. No doubt I'll come back to it in a year or two and find more that's relevant - a lot of the topics covered were ones I'll probably never handle.
Nothing more than the title says - Best Practices - nothing extraordinary, no tricks or something. Worth to take a look to check whether there is some missed best practice ;-).
