Use cases
Perfect Use Cases
Inventory Control Across Warehouses
Model Products→Inventory→Warehouses to track on‑hand units and updates in real time, preventing stockouts and overstock.
Order Lifecycle and Revenue Reporting

Customize
How to Customize
Add or rename entities
Tailor table names for your platform (e.g., add Promotions, Returns, or PaymentTransactions).
Edit attributes and constraints
Adjust columns, data types, and keys—set PKs, FKs, and unique indexes (e.g., SKU, email).
Map relationships and refine cardinalities
Connect entities with FK→PK links, define 1:N or identifying relationships, and document nullability.
Key Benefits
- Save hours of modeling with a battle‑tested ecommerce ERD
- Reduce stock and order errors through clear FK relationships
- Speed up analytics with a normalized, join‑friendly schema
- Scale confidently with multi‑warehouse and category hierarchy support
Pro Tips
- Use surrogate integer PKs; keep natural keys (SKU, email) unique for data quality.
- Document cascade behaviors (delete/update) to prevent orphaned inventory or order items.
- Version changes to entities and constraints so engineering and BI stay in sync.
