A Techno Blog, mainly about Java


I made it to the JUG meeting on JDO/EJB3.0.

I was paying more attention to the JDO information. He mentioned that the object relational mapping (I guess from a design perspective) consists of two step process : mapping (easy part), then making it quick.

Also, he said that JDO works with J2EE, but does not require it. Another point was the JDO defers the datastore decisions. Meaning the spec does not call just for relational databases.
Last point was that 20-40% of JDBC persistence is spent on persistence infrastructure.
