RDBMS Object-Relational Mapping vs. db4o

Store objects as seamless as serialization, with the flexibility and reliability of a full-featured database, but without the tedious O/R mapping overhead.


"We were experimenting a long time with relational databases, XML serialization, Castor, and with Hibernate to get the job done, but didn't see the results in response time and flexibility we expected for our native Java environment. We selected db4o because it meets our needs exactly for native persistence of complex objects.
I wish we had discovered db4o 2 years ago, because we would have easily shaved 6 months off our project time.
--Martin Kraus, Altana Pharma

"I am really impressed with db4o. The database is so easy to use - especially for embedded applications. db4o doesn't require any administration. It just works! And db4o's native object support makes it very easy to integrate with my Java applications."
--Marlon Machado, IBM

"db4o is just plain good technology. It is purposeful, cool, fun, impressive, well coded - all sorts of good."
