Oracle Discoverer 10g Handbook ReviewI have been reading this book since I got it a few days ago non-stop. Both at home (with glares from the Mrs.), and at the office (office door shut, of course) I am gleefully plowing thru this read. Now that I have just completed the book, I keep it within arms reach, as I will undoubtedly refer to it often, as Discoverer Administrator at my job.I have been using Discoverer now for about 5 years, but I have learned so much in the last few days with this book. "Chapter 20 - Configuring Discoverer" was, for me, the most insightful. It's Discoverer from a DBA's point of view (using OEM, setting the preferences, etc.) and knowing the settings and options that I don't get to see on a daily basis helps me better understand what is in the realm of possibility that I might not have known to ask.
Also key for me was the simple and conversational tone of the book. I, like many Discoverer users I would surmise, do not have an IT background, as Discoverer itself is so simple to use that it hides that complexity and lets you focus on the desired end result. This book is consistent with that spirit of Discoverer in that it's not a lot of technical jargon, and it's got lots of screen shots, so a person with little or no Discoverer experience can pick this up and use it immediately.
"Chapter 16 - Introducing Discoverer OLAP" was a great chapter as well, as it explains in detail the advantages of using the OLAP (as opposed to relational) feature of 10g. Even though I don't presently have plans for implementing it, it's so informative, I know what to expect if and when the need ever arises.
Finally, as an experienced Discoverer user, my favorite chapters were the appendices, specifically Appendix A and B. Appendix A are dozens of questions regarding the use of Discoverer, as well as scripts you can implement to make life easier (my favorite is the detail of the calculations to count business days between 2 dates). Appendix B is a comprehensive listing of Functions with examples, and I'm expecting that will be the part of the book I'll revisit most.
I highly recommend this book; it covers all aspects of Discoverer from report writing to administration, to portlet publication. Well-written and well worth the price.Oracle Discoverer 10g Handbook Overview
