2 — Designing Data Models

Covers data modeling for common system-design domains — user service, e-commerce, banking, messaging, and social networks.

3 — Scaling Databases

Covers the standard database scaling toolkit — sharding, replication, read replicas, caching, and CQRS.

4 — Interview Case Studies

Walks through database design for classic interview case studies — Instagram, WhatsApp, Uber trips, YouTube metadata, and Amazon's catalog.
