The service/daemon process is very simple. Call daemon() then do_something() and sleep(). You could create a very simple program/script (any language will serve that purpose) that starts by calling daemon() then sleeps until 4am and then parses the file and sleeps again. Alternatively you could just create a simple script that strictly parses the file and updates info on the database and add that script to crond/crontab.
Search google for "perl oracle" and come back when you have a script that does what you want so we can help you put it on crontab.
