CASE ANALYSIS
Scenario
A multi-branch computer retail chain needs a centralized inventory and sales model to track stock per branch, customers, orders, payments, and supplier relationships.
Key decisions
- Model inventory as a separate entity linked to both branch and product to capture per-branch stock
- Use composition for SalesOrder to SalesLineItem to enforce order line ownership
- Include enumerations for order and payment status to standardize workflow states
