Take a look in the db folder within any of the modules under mod to see how code works with the database.
Thank you for your help.
I found the function insert_record($table, $dataObject) in locallib.php, which is used in the function scorm_add_instance($scorm, $mform=null). This one appears in the db folder as you said, but i don't know if that's what i was looking for.

I reccommend installing an IDE such as NetBeans that will allow you to view the structure of the objects in Moodle more easily so you can see what bits of code do. Also take a look at the developer documentation on the database API.
