Wherever you got your notion of transparent persistence, I can tell that it wasn't from any persistence vendor, or somebody that understood persistence :-). Tranparency does not imply that there is no visible persistence API. What it...]]> Mon, 22 Nov 2004 10:10:02 -0500 Mon, 22 Nov 2004 10:10:02 -0500 Mon, 22 Nov 2004 10:10:02 -0500 Nov 22, 2004 Mike Keith 0 http://www.theserverside.com/discussions/thread.tss?thread_id=30017 It is hard to sell persistence for JDBC users, they do not have problem with persistence.

Hibernate supported transparent persistence. It works like the JDO. You just modify the object. Then commit the transaction. It makes the code very clean.

There are certainly small semantic and syntactic differences between the two specs, but those...]]> Sat, 20 Nov 2004 15:15:19 -0500 Sat, 20 Nov 2004 15:15:19 -0500 Sat, 20 Nov 2004 15:15:19 -0500 Nov 20, 2004 Abe White 0 http://www.theserverside.com/discussions/thread.tss?thread_id=30017 Sat, 20 Nov 2004 11:04:22 -0500 Sat, 20 Nov 2004 11:04:22 -0500 Sat, 20 Nov 2004 11:04:22 -0500 Nov 20, 2004 Eric Ma 1 http://www.theserverside.com/discussions/thread.tss?thread_id=30017 Down the road, are you guys confident that you can meet the independent release schedules followed by the 2 specs?

This is exactly how we see it with Versant Open Access. We will support EJB3 and JDO side by side in the same application. We already have a .NET JDO-like API using the same O/R mapping engine so this is not new :)
