Data modeling is how builders represent a product domain so the system can answer questions, enforce rules, and evolve without collapsing. AI can generate tables, but product-minded engineers know which entities matter, which access patterns dominate, and where denormalization is worth it.
These are the capabilities the app grades and coaches while you work through scenarios.
The same four moves apply across every discipline, but the evidence changes by track.
Frame the product domain, actors, rules, and access patterns.
List entities, relationships, events, and invariants.
Optimize normalization, denormalization, history, and tenant boundaries.
Win by explaining how the model answers future product questions.
Model a multi-tenant SaaS product with billing, usage metering, and audit logs.
Design the event taxonomy for an AI assistant product.
Model listings, bookings, payments, and disputes for a marketplace.

Open directoryYes. SQL asks how to retrieve or transform data. Data modeling asks what data should exist, how it relates, and which constraints the system should enforce.
A strong data model determines which product questions can be answered later: retention, monetization, fraud, usage, and customer health.
Public previews show the map. The app gives you reps, Hatch follow-ups, FLOW feedback, weak-move drills, and saved proof of progress.
