The experienced Java developer's guide to persistence with JDO!
Master JDO, the breakthrough technology for persistenting Java objects!
Java Data Objects (JDO) streamlines development by providing Java-centric mechanisms for making objects persistent, and standard APIs for connecting application code with underlying persistent datastores. Core Java Data Objects is the definitive, comprehensive guide to JDO persistence for every experienced Java developer.
Using realistic code examples, this book's expert authors cover creating, reading, updating, and deleting persistent objects; object lifecycles and state transitions; JDO classes and APIs; queries, architecture, security, and much more. They show how to integrate JDO with EJB, JTA, JCA, and other J2EE technologies; and introduce best practices for using JDO in both standalone programs and J2EE components.
If you want to spend more time solving business problems and less time worrying about persistence, you need JDO. And you need the one book that'll help you make the most of JDO: Core Java Data Objects.
Every Core Series book:
- DEMONSTRATES how to write commercial quality code
- FEATURES nontrivial programs and examples--no toy code!
- FOCUSES on the features and functions most important to real developers
- PROVIDES objective, unbiased coverage of cutting-edge technologies -- no hype!
Core Java Data Objects delivers:
- Practical examples showing how JDO can be applied to existing applications
- Powerful insights for using JDO to architect new systems more effectively
- Step-by-step guidance for integrating JDO with other J2EE technologies
- Best practices for using JDO in real-world business environments

Could have been better,
This review is from: Core Java Data Objects (Paperback)Java Data Objects (JDO) is an alternative to JDBC that allows you to treat rows from a database as Java objects. The simplicity of JDO removes many of the complications involved with developing JDBC applications. This book does a decent job of covering the JDO specification and explaining how to properly use JDO. The book starts with an introduction to JDO and shows some examples of how to write code with JDO. The section on the object lifecycle isn't clearly explained having too much concentration on lists and not enough on explanations. The following chapters do a decent job of explaining the pieces of JDO. In addition to the basics, the book covers using JDO in a J2EE environment with a look at Enterprise JavaBeans, security, and transactions. A later chapter shows a comparison of JDO and JDBC. The authors wrap up with some tips, take a look at what might be coming in the future, and show a case study.
The authors do not look at any JDO implementations, which leaves their... Read more

Good JDO Overview,
This review is from: Core Java Data Objects (Paperback)Java Data Objects (JDO) is a persistence framework to save Java objects to a datastore. The example code shows you how to create, read, update, and delete a persistent object using the JDO API. The book goes through the JDP API, especially the five main interfaces needed. The metadata, an xml file, that is needed for JDO is make clear in one chapter and the various options in the JDO xml file are explained to show you how to store your type of objects. The explanation of first-class and second-class object could have been longer. It seems like a more important topic and the brief mention in the book.
Part of the book shows you how to develop applications with JDO and the architecture scenarios where you should or should not use JDO. The third part of the book covers using JDO and J2EE application. The authors argue that JDO in most situations offers a better solution over EJB entity beans to store your objects or to use JDO and some direct JDBC. Practical examples... Read more

Don�t drop your JDBC yet!,
This review is from: Core Java Data Objects (Paperback)A good presentation for both architects and programmers, about JDO. The author explains the issues with Object oriented programs and relational databases then goes to show how JDO attempts to solve this mismatch (otherwise know as object relational impedance mismatch) Note from this book you will find that JDO is a standard to be implemented by vendors so that developers need not know varying interfaces object relational mapping frame works. JDO also has its own query language, which is not as powerful as SQL especially if you have complex joins or aggregation (OLAP) so, don't drop your JDBC yet! Well written with little fluff. It's not a O'rilly style code code book, it has the write amount of theory and code mix
