Databases & Data
Learn PostgreSQL
PostgreSQL is an open-source relational database known for standards compliance and a rich set of built-in data types.
Why teams use it
- No licence cost, which matters for smaller products and many-environment setups.
- Strong JSON support lets you mix relational and document-style data when that genuinely helps.
- Available as a managed service on every major cloud.
Where you will meet it
A product that needs relational integrity plus some flexible document-shaped fields often lands on PostgreSQL.
