# Relational Database

A type of database that stores its data organized into tables, made up of
columns and rows. Commonly, multiple tables are involved, each containing data
of a specific category (e.g., a table of users and a table of books), with
primary and foreign keys for each entry being used to describe the relationship
between entries (which books a user owns, for example). An example of a
relational database is PostgreSQL.
