Please add support for Neodatis ODB as database too (or instead of db4o).
Since the two are very similar, it wouldn't mean too much work, but it would bring several advantages:
- increased speed. The Poleposition test shows some of the numbers: https://sourceforge.net/projects/neodatis-odb/files/NeoDatis%20ODB%20Performance/NeoDatis%201.9/PolePosition_NeoDatis-1.9.pdf/download
(in my personal tests it was 3 times faster for many operations)
- better project structure, since the code would need a little refactoring to make the code persistence independent. I think this would greatly help other users understand you code (and maybe help with patches)
