Yes, but Mnesia has its limits. The paper pointed out by Tee
(http://erlang-consulting.com/thesis/dbms_eval.html) was researched when
we had to track about 200 million chickens a year (please do not laugh,
I am serious :-) ) undergoing about 5 or 6 state/ownership transitions.
That is where postgres, BDB and other hardcore databases come into the
picture. Mnesia is excellent for caching and storing live data, but not
for archiving or large quantities of rarely used data.
