Database Reference

The Digital Product Passport model is deliberately small: a passport belongs to a Magento product and a Store View.

Relationship Why it matters
dpp_passport belongs to one catalog_product_entity Connects passport content and identifiers to the product they describe.
dpp_passport belongs to one store Allows passport content and publication state to vary by Store View.

Use the passport management UI or service contracts for changes so validation and publication behavior remain intact.
