Java Data Objects (JDO): What It Is and Why It Matters
Ron Hitchens, Ronsoft Technologies

Track: Java
Date: Wednesday, July 09
Time: 4:30pm - 5:15pm
Location: Eugene

JDO is a new standard Java Extension recently finalized by the JCP. This session examines what JDO is (a standardized object persistence API), why it matters (it has the potential to revolutionize Java application design) and how it fits into the big picture (such as how JDO relates to its EJB cousin).

With JDO, almost any Java class can be made persistent - without making any code changes to the class. JDO provides a datastore-agnostic API for persisting objects. Objects may be stored in a relational database, an object database, flat file, or other media. The implementation detail of how object data are stored no longer need concern the object designer (or at least far less so).

This talk will discuss what this means in practical terms and why it has far-reaching implications for the future of Java application design.
