JDO
Java Data Objects. A Java interface to relational databases (not just SQL). It is somewhat higher level that JBDC. The corresponding query language is called JDOQL. Implemented by JBoss 4. It provides transparent persistent objects. I could in theory also be used on with PODs. It saves you the JDBC hassle of writing code to turn result set rows back into objects. Like SQL, the JDO standard has 22 optional features that you have to avoid if you want to remain vendor independent. Phht!
