Java Data Objects (JDO)

The Java Data Objects (JDO) API is a standard interface-based Java model abstraction of persistence, developed as JSR 12 under the auspices of the Java Community Process. If you are an application programmer, you can use JDO technology to directly store your Java domain model instances into the persistent store (database).

Getting Started With Java Data Objects (JDO): A Standard Mechanism for Persisting Plain Java Technology Objects

The Java Data Objects API provides a standard approach for achieving object persistence in Java technology by using a combination of XML metadata and bytecode enhancement. This tutorial covers the essentials.

Persist data with Java Data Objects, Part 2 - Java World

In Part 1, I provided an overview of available persistence mechanisms and their implementations, and introduced the Java Data Objects (JDO) approach to persistence. In Part 2, I conclude this series by looking more closely at the two competing JDO standards: the Sun Microsystems JDO and the Castor JDO. Both specifications provide unified, simple, and transparent persistence interfaces between Java application objects and data stores, and create an interesting alternative to entity beans.

Persist data with Java Data Objects, Part 1 - Java World

The need to persist data created at runtime is as old as computing. And the need to store object-oriented data cropped up when object-oriented programming became pervasive. Currently, most modern, nontrivial applications use an object-oriented paradigm to model application domains. In contrast, the database market is more divided. Most database systems use the relational model, but object-based data stores prove indispensable in many applications. Plus, we also have legacy systems that we often need to interface to.

Go-ForIt quest continues, Part 6: Create persistent application data with Java Data Objects

The dragonslayers wrote the most recent version of their Go-ForIt application using Struts and used the Data Access Object pattern to experiment with different technologies for persisting application data with minimal impact on the application code. This tutorial is based on their experiences developing Java Data Objects (JDO) that are persisted in DB2 Express using WebSphere Studio Application Developer and TJDO, an open source implementation of theJDO Speciification.

Hands-on Java Data Objects

Simplify your Java database programming with Java Data Objects (JDO), the first standardized, completely object-oriented approach to object persistence. This tutorial, which is designed for the intermediate to advanced Java developer with a solid understanding of relational databases, uses discussion, code samples, and hands-on exercises to demonstrate the practical application of JDO.

Introduction to Java Data Objects 2 (JDO 2)

The Java Data Objects 2 (JDO2) specification is an evolution of the JDO 1 Java API for object persistence. JDO relieves the need for Java developers to write complicated JDBC and SQL code. Applications written to use JDO for persistence are portable ...

Java Data Objects (JDO): An Object-based Approach to Transparent Persistence

For persistence storages, JDO provides a better and more efficient approach to application development.

An Intro to Java Object Persistence with JDO

The 'impedance mismatch' between relational databases' tabular orientation and object-oriented Java's hierarchical one is a perennial problem for which the Java world has several good solution offerings. The third in a three-part series, this article examines the ways that JDO attempts to simplify the chore of connecting relational databases and the Java programming language.

Petition drive seeks Java Data Objects upgrade | InfoWorld | News | 2005-02-09 | By Paul Krill

An Internet petition has been posted urging an upgrade to the Java Data Objects specification for Java object persistence, amidst a movement by the Java Community Process to merge JDO with EJB.

What is Java Data Objects? - a definition from Whatis.com - see also: JDO

Java Data Objects (JDO) is an application program interface (API)that enables a Java programmer to access a database implicitly - that is, without having to make explicit Structured Query Language (SQL) statements.

O'Reilly - Safari Books Online - 0596002769 - Java Data Objects

0596002769 - Java Data Objects - This book, written by the JDO Specification Lead and one of the key contributors to the JDO Specification, is the definitive work on the JDO API. It gives you a thorough introduction to JDO, starting with a simple application that demonstrates many of JDO's capabilities. It shows you how to make classes persistent, how JDO maps persistent classes to the database, how to configure JDO at runtime, how to perform transactions, and how to make queries. More advanced chapters cover optional features such as nontransactional access and optimistic transactions. The book concludes by discussing the use of JDO in web applications and J2EE environments Whether you only want to read up on an interesting new technology, or are seriously considering an alternative to JDBC or EJB CMP, you'll find that this book is essential. It provides by far the most authoritative and complete coverage available.
