It is most often embedded in a Python program, but you can also connect 
ZODB to a ZEO server.

Both ZODB and ZEO are free and open source software.

Only if you design the object system to allow queries.  ZODB is not a 
relational database, it's an object database.  ZODB does not contain 
tables and rows, but rather one large collection of pickled Python objects.

I hope my answers helped.  If you tell us (the subscribers of the ZODB 
development mailing list) what you're trying to accomplish, we may be 
able to provide better answers.
