The Persistence API does not conform to an existing standard such as JDO. To do so, we believe that both usability and performance would be compromised.

Like most Java programmers, I don't know or care that much about database programming
Sad truth.
don't bother the Java programmer with database optimizations.
Rather unproductive and unhealthy...]]> Sun, 12 Feb 2006 05:00:08 -0500 Sun, 12 Feb 2006 05:00:08 -0500 Sun, 12 Feb 2006 05:00:08 -0500 Feb 12, 2006 Radu-Adrian Popescu 0 Relation by ID http://www.theserverside.com/discussions/thread.tss?thread_id=38916 From what I understand, Object allocation and deallocation in modern JVMs is much faster than in C so the cost of temporary Objects is low.
There's no such thing as C.
