"network" could be abbreviated to "net", "inventory" to "inv" (maybe OK
in this context; in another context it could an abbreviation for
"inverse"), and "connection" to "con" (maybe), giving "net_inv_db_con",
or "net_inv_db_connection".

The trick, of course, is to make it clear, but not annoyingly long.
Python itself has "def", "len", and "lstrip", not "define", "length"
and "left_strip".
