JDO is coming to HK again. In the past two years, JDO made some noise in the field of Java. JDO provides a revolutionary data persistence standard, but it is charged for its weaknesses. In this year, JDO 2.0 (JSR 243) was passed in the JCP Review Ballot under objection from major vendors and released an Early Draft Review. With two years, do JDO implementations become more maturity? How is the new JDO 2.0 features? HKJUG will present a seminar with a local partner of a major JDO vendor on August 28.
