Java Data Objects

Organization

This book has 17 chapters and 5 appendixes. The first three chapters provide a good overview, showing a complete example, a high-level overview of the JDO interfaces, and a discussion of the architectures in which JDO can be used. Chapter 4 through Chapter 6 deal with object modeling, schema design, and aspects of the JDO software-development process. Chapter 7 covers aspects of establishing a JDO runtime environment, which includes connecting to a datastore and issuing transactions. The remaining chapters cover aspects of using JDO to store, access, and query instances in the datastore. We start by presenting the basic concepts and gradually move to more advanced topics, including features that are optional in JDO implementations. We complete the book by discussing how you can integrate your applications into application-server and J2EE environments.

The following list provides a brief description of each chapter and appendix:

Chapter 1

Provides an introductory overview of JDO by walking through a small application that illustrates many of JDO’s capabilities.
