Best python module for Oracle, but portable to other RDBMSes

[dananrg at yahoo.com]

What would be the next best Oracle database module for Python next to
cx_oracle? I'd like to compare two and choose one, just for the sake of
seeing how two modules doing the same thing operate.

Also, does installing cx_oracle create registry entries or require
admin privs on a Windows XP machine? I see that cx_oracle is
distributed as an EXE.

Thanks.
