it might be useful if you have a bunch of unknown properties (e.g. configuration
parameters for some external parameters), and no need to access the properties
as individual parameters via the database.

some database drivers have API:s for this, but if you're using a generic
DB-API driver, it's pretty straightforward to generate an appropriate SQL
statement on the fly; e.g.
d = {"spam": "1", "egg": "2"}
cols = d.keys()
vals = d.values()
stmt = "INSERT INTO table (%s) VALUES(%s)" % (
",".join(cols), ",".join(["?"]*len(vals))
)
cursor.execute(stmt, tuple(vals))
