Link of Product and Model

Hi Christopher, Thank you for the info about the null relationship concept. But when I query the Model table I dont see any column where the related product information is stored. I see there is one column 'Related_Id' but the is also null. Am I missing something? :(   ----------------------------------------------------------------------------------------- Please also tell me the concept of 'config_id' in Innovator db, I mean there is this other column called 'id' right? then why config_id is used? I have noticed that, when I create one record in Innovator, a row gets added in DB with same 'config_id' and 'id'. And when I modify that record again, a new row gets added into db with a new 'id' but same 'config_id'.   Thank you.
