About Notion database
The part of Notion that behaves like a database.
Notion is a workspace product from Notion Labs, started in San Francisco in 2013 by Ivan Zhao and Simon Last, with the current version live since 2016. Inside that workspace, a Notion database is a typed table: every row is a page, every column is a property with a type. Properties cover the obvious ones (title, number, select, multi-select, date, person, files, checkbox, URL, email) and the relational ones that make Notion punch above a spreadsheet (relation, rollup, formula, status, unique ID, last-edited-by, last-edited-time).
That property layer is what makes Notion databases interesting to land in a warehouse. A team's CRM-lite, hiring funnel, OKR board or project tracker is structured data with foreign keys, computed fields and a query API behind it. Pulling it through the official Notion REST API gives you the raw rows, the property schema and the relations between databases, so the side-system that started as 'we'll do this in Notion for now' can be reported on, joined to the CRM, and audited like any other operational source.
