Database schema questions (CS-Cart Ultimate)

Storefronts (SF) vs Companies (C):
What is the difference between and Are they kept in sync via admin when editing using Administration > Storefronts?
Are C.storefront and C.secure_storefront still used or is SF.url the only URL that matters?

I answered part of my questions. After updating the Storefront URL via Administration > Storefronts > select storefront to edit, I found that the all three columns were updated in the database: cscart_storefronts.url, cscart_companies.storefront and cscart_companies.secure_storefront


Yes, the cscart_companies and the cscart_storefronts tables are linked between each other in CS-Cart Store-Builder.
