  • An introduction to JDO 2.0 using JPOX and DB2 Universal Database by Robert Peterson, Kulvir Singh Bhogal   - [Clicks: 192]
    The Java Data Objects (JDO) specification introduced by the Java Community Process (JCP) is a framework which persists plain Java objects to a data store such as an RDBMS. Java Persistent Objects (JPOX) is a JDO 1.0 (JSR 012) and JDO 2.0 (JSR 243) compliant implementation. This article shows how to use the JPOX implementation to abstract the tedious writing of SQL to persist and retrieve data from your DB2 Universal Database (DB2 UDB) database. We showcase JPOX 1.1, which has been chosen by the Java Community Process to be the reference implementation of JDO 2.0. JPOX is released under the Apache 2.0 open source license and is free to use.

  • An Intro to Java Object Persistence with JDO by Jeff Hanson   - [Clicks: 209]
    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.
