Thanks very much for your information
But I would like to know how I'll write and retreive my objets when my 
system will be written in Java. At what time or how I'll switch to Python.
My system is intended to supervise a network and get objects (as processor 
attributes, system attributes ...) and after I would like to save these 
objects in an Object database (I think is more simple). Is for that I would 
prefer to use ZODB. But is it possible?
