New dOCL license fosters rapid adoption of db4o in wider range of open source projects SAN MATEO, Calif., Jan. 24, 2007 - db4objects (www.db4o.com), creator of the leading open source object database, today announced the introduction of a third licensing option dubbed dOCL (db4o Opensource Compatibility License).

German, ''db4o is not experimenting in new legal ground here (for example MySQL has the same dual licensing scheme)'' Precisely the reason that I (and others) pick and choose GPLed applications and libraries based upon the organization in control.  As a GPL licensor myself I often prefer to direct people to Creative Commons' published ...

Well, I found the answers to my own questions: http://www.db4o.com/about/company/legalpolicies/gplinterpretation.aspx I'm sorry that there appears to be a disagreement on this issue, but I do feel that db4o's policy as written on the above webpage is a poor choice.  I understand that db4o feels a need to be profitable, but abusing Copyright ...

Actually we can talk with Microsoft about that. But the result will be the same ...

Rogério Weinert:VistaDB costly about 250 USD a royalty-free license and is far more stable and perfomanced than DB4O, but of course, is a relational dababase. I'm not sure that VistaDB far more performanced (haven't seen your tests). Our tests shown that it's sometimes slower, sometimes faster...VistaDB really not so mature as Microsoft SQL ...
