Databases

Level: L2 | Domain: devops

Databases are the persistence layer for nearly every production system. Choosing the right database requires matching access patterns (key-value, relational, document, time-series, graph) to the strengths of each engine, while accounting for ACID requirements, scale projections, and team expertise.

This topic covers the landscape of database technologies, their operational trade-offs, and the decision frameworks for selecting and running them in production.
