Relational Database
A database model that organizes data into relations, usually represented as tables.
Motivation
A relational database stores data in related tables. It solves the problem of querying structured data consistently and safely.
Mental model
Relations, keys, constraints, and SQL make data explicit and queryable.
Where it fits
Relational Database belongs to the Software track, inside Databases. It connects to nearby concepts through the graph relationships on this page and in the graph explorer.
Common mistakes
- Treating tables like arbitrary files.
- Ignoring indexes until performance collapses.
- Assuming every schema change is easy at scale.
