  • Real‑world fields (emails, ratings, prices, stock, snapshots)
  • Analytics‑ready structure for revenue, ratings, and inventory
  • Easy to extend for payments, promotions, or shipping

Perfect Use Cases

Launch an MVP marketplace quickly

Start with a complete, normalized ERD so engineering can implement models and migrations without ambiguity.

Compare your current tables to this structure to spot gaps, streamline joins, and plan safe migrations.

Build an analytics warehouse

Compliance and audit readiness

Snapshot fields (unit_price, shipping_address) preserve history for disputes, refunds, and reporting.

Add or edit entities and fields

Insert new tables (e.g., Payments, Coupons) or extend attributes like tax_rate, currency, or fulfillment timestamps.

2

Adjust relationships and constraints
