Database Management Systems

A book-shaped table of contents for DBMS: relational foundations through SQL mastery, storage internals, transactions, distributed databases, NoSQL, and MAANG interview prep — cross-linking existing system-design/patterns notes instead of duplicating them.

1 — Choosing the Right Database

Covers how to choose a database for a system design — SQL vs NoSQL, read-heavy vs write-heavy workloads, time-series, and graph use cases.

2 — Designing Data Models

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

4 — Interview Case Studies

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