Using relation & rollup properties
Notion databases become even more powerful when you link them together. Link to a row from another database with a relation, or show a specific property from a related table with a rollup.
Notion allows you to connect items across multiple databases using Relations and Rollups.
Relations allow you to connect pages from one database to another.
Rollups allow you to pull specific properties from a database into another database.
As an example, you could connect the Tasks and Projects databases of an Engineering team.
Create a Relation property in the Tasks database to link each task to its corresponding project. The changes made through Relations are reflected in both databases.
Rollups can be used to aggregate data from one database to another, such as calculating the total estimated dev time for a project from individual task times.
As your workspace grows, Relations and Rollups offer more opportunities to make sense of your data.
