Short answer: use a Rollup.
Here’s how to make a property from a related database show up in your current database:
- Open your database → + Add property → choose Rollup.
- In the rollup settings:
- Relation: pick the relation property (the link to the other database).
- Property: choose the specific property from the related database you want to surface (e.g., Status, Due date, Owner).
- Calculate: pick how to display it (e.g., Show original / Earliest date / Checked / Count / Show unique etc., depending on the property type and number of related pages).
- Make sure that new rollup column is toggled on in your view (⋯ → Properties).
Tips & gotchas
- If the relation links to multiple pages, choose an aggregation that makes sense (e.g., Show unique, Earliest/Latest, Percent checked).
- Want to massage the rollup value (e.g., combine text or format dates)? Add a Formula property that references the rollup.
- On boards/gallery, choose what shows on cards via … → Layout → Card preview / Card properties.
- If you need the property to appear on the other database’s side of the relation automatically, open that property’s settings and look for the option to mirror/show it on the related database (Notion calls these “shown on relation”/mirrored properties). Availability varies by property type.
