Rezension bezieht sich auf: Cost-Based Oracle Fundamentals (Expert's Voice in Oracle) (Taschenbuch)
The book covers in great detail many internals of the Oracle Optimiser, including comparisons from Oracle 10 to 8. The author also shows how to set up and test these things, starting with the details of single table access (and there's a surprising amount of detail to be aware of even for a 'simple' single table access) and building up systematically from there.
Why only 4 stars? At times this book focuses too much on detail - especially in the style of writing. It is sometimes hard to get to the concepts from this detailed point of view. Of course the author provides summaries per chapter. However many of the chapters start with some script and the resulting details of this script. The concept this leads to is then mentioned later on in the chapter - it's mostly a question of personal taste. Personally I prefer the style of writing in Guy Harrisons book on the same topic, however Harrison is not as detailed and the Harrison Book only covers Oracle 8, while this one has information up to Oracle 10 Release 2.
So to sum this up: Recommended for anyone interested in the real details of performance tuning and how the optimiser works / where the pitfals are. Only negative is my personal (dis)taste for the style of writing.
