title: How does Magento save ordered products in database?
body: <p>After I send an order , how does Magento save the order products (in sales_flat_order_item table). I need the files, because I want to save  the regular price in database also; if you have special price Magento only saves the special price in database when somebody make an order. 
  Or does anyone have any idea how can I save the regular price in database for each ordered product?</p>
