Obviously it depends on the application, generalities are dangerous.

But one advantage of DBs are that you automatically get all the
mechanics of failover, distribution, backup and recovery, atomicity,
consistency, integrity, security, etc. that come with the DB
essentially for "free".

There is a tendency that one starts with this idea of keeping it
simple, such as text files, and then proceeds to build all these
mechanisms themselves, usually poorly.

Look at how many different formats of configuration files we have on a
typical *ix system, nearly one per application/daemon that needs a
config file. Why do I have to know how to properly modify a passwd
file, named config, logrotate, tcp wrappers, mail daemon configs,
anti-spam configs, etc etc etc (usually in /etc!) down to what they
will each take for a comment or separator or stanza syntax.
