How recurring physical commerce is modelled: plans and subscriptions, one row per billing cycle, preferences that drive curation, per-cycle box contents, shipments, skips and pauses, churn reasons and referral credit.
How a marketplace models many sellers listing the same product: a shared catalogue, competing offers, the buy box decision as a log, orders split into per-seller sub-orders, fulfilment, payouts and product-level reviews.
A production-shaped e-commerce schema: products with variants, inventory per location, carts, orders with snapshotted line items, payments and shipments. Open it in the editor or export SQL for six dialects.
How a handmade marketplace models its data: shops and sections, made-to-order listings with variations and personalisation, cross-shop carts, orders split per shop, shipping profiles and photo reviews.
How an in-store point of sale is modelled: stores and registers, cashier shifts with opening float and closing count, sales with discounted lines, multi-tender payment, returns against the original sale, drawer movements and approved price overrides.
