I have checked some tutorials to create custom shipping module in user panel where sellers can update carrier information and tracking information. However, all are available for admin panel. I need to create in user panel. I know, how to create module for Magento. However, I am not able getting starting point where to start and which module I look through.
In Admin dashboard, admin can update the shipment information like which carrier is used for shipment and what is the tracking number. Is this module is using flat table in database?
