Salesforce Commerce Cloud is a collection of objects that support complex storefronts. The Salesforce Commerce Cloud ERD have natural grouping that make it easier to understand how they support building out your businesses storefronts.
The following are the grouping i've put together:
Store
Product
Buyer
Cart
Promotion
Order
Payment
Shipping (The latest edition!)
In these two videos I break down these groupings and explain each object and how they're connected to the larger picture.
