Product Description

Review

From the reviews:

"The book is a guide to db4o, a tool for building object database management systems. … This well-designed book covers the programming techniques with Java 1.4 and 1.5 and .NET 1.1 and 2.0; the authors also show that db4o supports both Java and C#. The concepts of object-oriented programming are covered well. … The position of db4o in the world of relational data is discussed throughout the book. This makes for interesting reading." (S. Balaraman, ACM Computing Reviews, Vol. 49 (2), February, 2008)

Product Description

To satisfy the demand for 24/7 information access, applications available in airport and conference kiosks, and in the mobile, gaming, and medical industries, provide consumers data access wherever they are. But its essential that fast availability not be traded for quality performance.

A prominent solution for managing the data in these applications and devices is db4othe open source object database native to the Java and .NET platforms. Highly reliable and scalable, db4o cuts down on development time by smoothly integrating into the system, cutting out the otherwise costly object-relational mapping typical of larger applications.

The Definitive Guide to db4o is the first book to comprehensively cover this project in detail. You will learn about all relevant topics, including installing and configuring db4o, querying and managing objects, performing transactions, and replicating data. To aid newcomers to the topic, early chapters cover object database fundamentals, as well as technical considerations and migration strategies. The book is complete with numerous C# and Java examples, so youll be able to follow along regardless of your chosen language.

4.0 out of 5 stars Good book for many purpose, July 24 2006

By Alain Demers "GIS developer" - Published on Amazon.com

This review is from: The Definitive Guide to db4o (Hardcover)

I used db4o during the last six months. I awaited this book for a long time. It provides much useful information about building applications using the db4o. Instead of the level of technical detail, the book is easy to read.

In the very interesting Part I, the concept of open source native object database is introduced along with little history where object database came from. It also provide some useful background with regard to why the relational data model is not an ideal fit for objects.

Part II step the reader through the processus of building a first db4o application and gives details for the inner working of db4o. The exemples are incrementally skilled with each step in the evolution of an application. It provide a lot detail on the topics covered in the earlier chapters. The chapters 7 through 9 are concerned with making the reader understand what each of the db4o parts actually does and how you can use the various functions to tune the behavior of the peristent part of your object application.

The chapters of the Part III are great reference materials and introduces the readers to the rules you need to keep in mind while you came from RDBMS. It compare db4o features compare to the traditional SQL query-driven application. Comparison between RDBMS and OODBMS is a common theme in each chapter of this book. This Part gives you a new and open mind about persistent data in object application. I am happy that it gives you when RDBMS is good and when OODBMS is better instead of seeking to make me believe that OODBMS is the universal solution (but from my own experience, when objects are complex, it is the only solution). You will understand how db4o features compare to the SQL query-driven approach, how db4o query performes and when it is suitable for your application.

I am happy by this book for two reasons. Firts, it provides much needed high-quality documentation for building fully object oriented applications. I mean object data model with object database. Second, it provides the information in an almost easy-to-understand progressive manner. I learned a lot more about db4o by reading this book, and I also learned a lot about object database in a more general sense. I recommend this book to anybody building an object application and don't want to tediously map objects to database table and depend on a string-based query language to manage and retreive the data.

4.0 out of 5 stars Great book, but some stuff is already a little out of date, Nov 9 2006

This review is from: The Definitive Guide to db4o (Hardcover)

Great book for anyone thinking about using an object database. Db4o is an awesome database to use for your projects. This books is a great way to get yourself in the game. The only thing is that the book is written for version 5.2 and 5.7 is already available for download and the new stuff in 5.7 isn't in the book.

4.0 out of 5 stars An alternative to RDBMS? Maybe..., Jun 26 2009

This review is from: The Definitive Guide to db4o (Hardcover)

Ran into this book accidentally, and glad it happened. Definitely worth reading if you are looking for something that would take you a step beyond the traditional O/R mappers.
