| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Java Data Objects
(JDO) is a specification of Java object persistence. One of its features
is a transparency of the persistent services to the domain model. JDO
persistent objects are ordinary Java programming language classes
(POJOs); there's no requirement for them to implement certain interfaces
or extend from special classes. JDO 1.0 was developed under the Java
Community Process as JSR 12. JDO 2.0 was developed under JSR 243 and was
released on May 10th, 2006. JDO 2.1 was completed in Feb 2008, developed
by the Apache JDO project. JDO 2.2 was released in October 2008. JDO 2.3
is in its planning stage. JDO 3.0 will be released around June 2010. |
