Insert new order item

[OriyanJ]

I've created some data that being generated at cart view, I would like to insert that data to the order. Assuming I've allocated fields in the database and order object, how can I insert that data to a new order being made?
I'm not looking for the entire solution, just a direction.

What I eventually did was inserting all the data I needed into a custom field plug-in as an array. I still hope anyone would be able to direct me to a better way.
