Business Model
The Business Model sample is a conceptual design: a set of core business entities — Customer, Order, Product, Invoice, Payment, Shipment, Supplier, Warehouse, and more — with the relationships between them.
It contains metadata only (no templates): data objects for the business entities and mappings that express how they relate, such as Order to Customer and Shipment to Warehouse. This makes it a good starting point for conceptual or business modeling, and a quick way to explore the Design screen with a recognizable model.
