See
http://www.python.org/doc/current/lib/module-bsddb.html
and
http://www.python.org/doc/current/lib/module-anydbm.html

In brief you use it as a python dictionary. You have to
use a special constructor where you supply the file name
and maybe some other parameters, instead of just doing
db = {} as you would with a dict. After that you basically
treat it as a dictionary, and your data will magically persist.

The database will be created when you open it the first
time. There is nothing like a database schema or anything
like that. A simple db[key] = value will create/update a
record.

I have a little warning, although it might not be an issue
with recent versions: If you open a database and don't store
any data, an empty file will be created. Next time you try
to open it, you will get an error, since it's not recognized
as a database file. But maybe that's fixed by now. It's been
some time since I used it.
