Eh? I'm not talking about ACIDity. I'm talking about the horse people love to beat about loosing your data due to vendor lock-in, completely ignoring that there's no rational difference with your average RDBMS. On the subject of ACIDity though, here's a developer press-release on an older version, along with benchmarks and tests for crash simulations: http://developer.db4o.com/blogs/product_news/archive/2006/06/02/25420.aspx Now, could be that you just don't trust them. Ok, but since it's unlikely you've vetted your RDBMS of choice in the same manner, is that really fair? (Just an idea, not accusing you of anything; you very may well have written a suite of tests to verify your RDBMS acidity. :)
