SQL Utility Data

This is a clean relational data set for regions (UN M49), countries (ISO 3166-1, UN M49), languages (ISO 639-1) and currencies (ISO 4217) to be used in your project.

Tested with PostgreSQL 14

Why use this one over other data sets available on GitHub?

• Up to date as of the date of the last commit
• Manually checked for errors
• Relational mappings
• PostgreSQL compatibility
• Supports countries with multiple currencies
