Add products along with logged in user id

hello,

i have a website with 2 roles - retailer and customer. the retailer adds, deletes, updates records. different retailers can add the same product. is it possible to add the records by retailer? i mean if the same product is added, it should be linked to the retailer that added it so that i can later query and retrieve records by retailer. i have a retailer table in my database.

any tutorials that i can go through?

any ideas how to do that?
