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...

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...

In the march towards higher levels of abstraction and more powerful coding approaches, Sun came up with Enterprise Java Beans several years ago. But despite one's best efforts, instead of focusing on writing business logic in a modular, fully encapsulated way, you often also have to deal with reading and writing to a persistent format; usually a relational database. The gritty details of the impedance mismathc between your...
