Query: Straight Advice from Serious Designers

With this book, the authors help bring focus to the physical design phase. Practical advice can be found that will apply to most RDBMS implementations, and the Oracle-specific topics are "dead on". Though this book covers Oracle v7, their companion "Oracle8 Design Tips" fills the gaps nicely. In my teaching and consulting practice, this book has helped quite a lot. I rarely leave home without it.
