Finally, I could manage some time writing up the follow-up post about other interesting features of db4o, specifically about client-server feature and transaction & concurrency support. You can read the article here: http://www.codeproject.com/KB/cs/oop_db4o_part_2.aspx.
This write-up also gives me a chance to learn about some cool new features of db4o 7.2 (currently development version) such as LINQ integration, transparent activation and transparent persistence. These are really big changes from the previous version I tried (6.3). Hope that I can find some time writing about all these features. But don’t wait for me though, just go ahead and try them yourself…
