5.0 out of 5 stars Must a read book, 30 Nov. 2007
I am currently working on system, the involves Oracle Spatial technology. This book was going to be me first step (almost) towards getting familliar with Spatial. I was little anxious about the level expected from the book's reader: "Intermediate-Advanced"; I haven't exactly felt like "advanced" in Oracle technology. It wasn't so bad; the book is really well written and I had no problems with understanding anything.

The book consists of six parts (including appendices). All the parts cover following subjects:
- Introduction to the technology. Technologies, to be exact; architectures of both, Spatial and Locator options are described -
differences between them.
- Basic concepts - basic know-how. The part, I needed the most met my expectations in 100%. It helped me to start coding really fast.
- Network analysis - more advanced subjects covered, the mostly ARE NOT available in Locator option (one I have access to); network analysis and routing engine, geometry engine. Also indexes and operators are described in one chapter of the book.
- Map Visualisation and creation - a lot of knowlege about MapBuilder, MapViewer and it's API - really helpful for anybody, who needs to visualize maps stored in Spatial.
- Sample applications and case studies - I always look for such chapter in every IT book I read. This is the place, where programmer might find a lot of answers to one's questions. There is also a chapter in this part, the belongs to the category "MUST read" - "Tips, common mistakes and common errors".

There is also sample code available for the readers - to be downloaded from the publisher's web page. It is really helpful to have it while reading the book. There is only one "but" - was, to be exact. About two weeks after the book had been published, the code wasn't available on the page. At least, I couldn't find it. Now it is possible to download it from here.

The book is really good - "must have" of every Oracle Spatial user. It might be helpful for the beginner and advanced developers as well. I would recommend it to everyone, who needs to get to know Oracle Spatial well. All the 756 pages (excluding index) are filled with reliable knowledge, especially that one of the authors - Ravi Kothuri is a member of Oralce spatial development team, where he works as software architect and team leader.

5.0 out of 5 stars Wow. What a great book., 24 Nov. 2007
Wow. What a great book.

I took this book, because it is very short, just 168 pages. I asked myself, what this guy can say in just 168 pages about performance? Maybe some introduction to the topic? First two chapters just confirmed my assumptions. There is nothing new, just some general information that I already knew.

How big was my surprise when I finished chapter 3 - first rule (out of 14). Author was able to explain what is the problem with too many http requests and how to make fewer requests. Even I am not a performance guru (just a developer) it was clear enough how should I build my web pages in the future. Even more, he gave me a felling that I should change my current pages.

Next couple chapters are even better, especially description how important is to put css and js imports in the correct place on web page, and how big impact they might have when they are in wrong place. The chapters about Expiry headers and ETags are also awesome. Author describes how cache in web browser works, what are conditional gets and how to make a proxy more efficient.

I finished a book with a feeling that I can easily change my pages to work much faster than they are today. And you know what - I will not spend much time for that one.

I recommend this book for everybody who writes web pages even for personal use. You will be surprised how big amount of knowledge you can get from 168 pages.
