[uml-devel] Example databases to keep humfs metadata

[Piotr Neuman]

gdbm: http://www.gnu.org/software/gdbm/gdbm.html

Simple file database, using hashing. Should be relatively easy to include with 
UML sources. It's pretty standard in all Linux distributions.

qdbm: http://qdbm.sourceforge.net/

More up to date than gdbm. Also has B+tree algorithms, so it may be more 
apriopriate for filesystem data. Disadvantage is it's larger size but I 
believe it could be trimmed down for UML.

API similiarity between gdbm and qbdm should allow for easy transition if 
needed.

Berkeley DB: http://www.sleepycat.com/

Very powerfull (logging for example) but it's features are rather overkill. 
Advantage is that it's available on all major distributions (UML could link 
to it dynamically).

Those are just a few possibilities, I'm sure there are other options (like 
open source SQL databases ;).
