In February we had a great presentation on Web Services, SOA and ESB by
Chris Haddad.  I was very happy to see the volume and quality of the
questions as it seems a number of our membership is actively researching and
developing in these areas.

This month's topic:  JDO - Java Data Objects with Patrick Linksey
Over the last 12 months we have covered most aspects of the data access tier
(O/R mapping and persistence) in a J2EE application with presentations on
TopLink, Apache OJB and Hibernate.   This month we will focus on JDO.  In
2002, the Java Data Objects (JDO) specification was approved through the JCP
in a landslide vote 14-0.  By November of 2003, a survey showed that 25% of
people interviewed were using JDO or considering JDO for their projects in
the next year.  In less than 18 months, the Java Data Objects specification
went from a proposal to the de-facto standard way for persisting objects.
Developers using JDO are seeing increased application portability, reduced
development cycle time, improved code quality, higher performance, and more
manageable scalability.  There are over 20 JDO implementations available
today.

The session will highlight the problems of persisting data to a database,
the basics of JDO, a comparison of JDO to other persistence solutions
including JDBC, serialization, and entity beans, the JDO Query Language, and
patterns on how JDO can be used to improve scalability and performance of
Java applications.
