Korry Douglas is the Director of Research and Development for Appx Software. Over the last two decades he has worked on the design and implementation of an umber of high-level languages and development environments, and his work with a variety of database products (Oracle, Sybase, SQL Server, PostgreSQL, MySQL and mSQL) given him a unique understanding of the commonalities of, and differences between, databases.
The second edition of the best-selling PostgreSQL has been updated to completely cover new features and capabilities of the 8.0 version of PostgreSQL. You will be lead through the internals of the powerful PostgreSQL open source database chapter, offering an easy-to-read, code-based approach that makes it easy to understand how each feature is implemented, how to best use each feature, and how to get more performance from database applications. This definitive guide to building, programming and administering the powerful PostgreSQL open-source database system will help you harness one of the most widely used open source, enterprise-level database systems.

a very comprehensive book, By
This review is from: PostgreSQL (2nd Edition) (Paperback)
This book lives up to it's claims for "the comprehensive guide to building, programming and administering postgresql databases". I'm a MySQL guy, but may have to do a little pgsql to support a third party app, so I was looking for a book that would bring me up to speed.The quick review is this... I give this book 3 stars, because it's so huge and covers so much territory that, in my opinion, it does a middling job of it. I would have preferred a more focussed book. I think, given it's goal of being so comprehensive, it is about as good as it could be and if you really need to know everything - from sql, to developing extensions, to embedding this in your c/c++ programs and administering things AND want a single book that covers it this is probably the book for you. If you don't need quite that much, or are willing to go to more than one book to get it, I think you would be better served to look elsewhere. The longer review... Honestly, I don't know... Read more

Many trees died in vain, By Toomas Vendelin (Tallinn, n/a Estonia) - See all my reviews
This review is from: PostgreSQL (2nd Edition) (Paperback)
This "complete reference" is a total mess. It took quite a while to find out how to stop the server otherwise than by "kill" command, because "Server startup and shutdown.....779" refers to a text block which says that "we'll explain it in the next chapter".Also, buying a tome of 1000+ pages, you would probably (and rightfully) expect to find a complete syntax reference to such essential commands as CREATE TABLE. I didn't find one! There is only a brief introduction to the basic syntax. Normally, books of such volume contain several appendixes in the end, like "PostgeSQL syntax", "Perl API syntax", etc. Not in this one. The bottom line is, buy "Beginning databases with PostgreSQL" by Neil Matthew and Richard Stones. This book will get you started quickly and painlessly. This book is a bit over 600 pages, and is very clearly written.

Surprisingly advanced, By
This review is from: PostgreSQL (Paperback)
I was surprised at how advanced this book was. It starts with the usual introduction to basic SQL access to PostgeSQL, then has a two chapters on data types and syntax, and then jumps straight into performance and extensions stuff. It then covers PL/pgSQL. The majority of the second section of the book is examples of writing for Postgres with various programming languages (e.g. C, C++, Java, Perl, PHP, Python, etc.)I liked the advanced content, but I was looking for a book on Postgres basics. So I don't think I got the right thing. My advice to you is, check out the table of contents, and make sure you are getting the content you need. If you are looking for a basic Postgres reference, this is not going to have much content for you. |
