[Hibernate-JIRA] Closed: (HHH-1428) PersistenceManager Pattern (request for comments)

I apologize for that. > Talking about Persistence we cannot limit ourselves to proper RDBMS's or other systems with proper JDBC drivers and proper structured query languages dialects. Hibernate is hot, but as a programmer i hav had to build a custom interface in order to hide Hibernate implementation because i wanted to use a unique PersistenceManager interface for persisting objects in any way. My first problem was when i wanted to persist dynabeans, but now there is some development activity in that sense.
