ABSTRACT: The Java Data Objects (JDO) Specification
Earlier this year, the Java Data Objects (JDO) specification was approved through the JCP in a landslide vote 14-0. The Java Data Objects specification provides a standard way for persisting objects and is showing a great deal of promise by increasing application portability, reducing development cycle time, and improving code quality. Applications written with JDO can be ported seamlessly across any data store without any recompilation or changes at the source level. Developers using JDO are seeing 20-40% decrease in coding. Java Data Objects works equally well in managed environments as well as non-managed environments. The following topics will be presented:
a. Introduction to the JDO standard;
b. The benefits of the JDO API;
c. A comparison of JDO to other persistence APIs;
d. The JDO enhancement process;
e. JDO’s public interfaces;
f. Examples of how to persist data using JDO ;
g. Examples of how to retrieve data leveraging the JDO Query Language (JDOQL);
h. A description of how to use JDO with EJBs
