One could also mention failover: if one computer with Data.fs goes down,
you're down, period; whereas many RDBMSes support keeping slave copies
of the database, which are then available.
Also, there are ACID transactions (see
http://en.wikipedia.org/wiki/ACID) in a good RDBMS. I don't know how
zodb ensures consistency if there are multiple concurrent users, and can
we rollback gracefully?
