Relations
Real data is connected — posts have authors, products have categories. Relations let a record reference other records.
Plan availability
Pro.

Reference fields
Add a reference field to a model to point at records in another dataset (or the same
one). For example, a post can reference its author.
Many-to-many
Relations support many-to-many, so a record can link to several others and vice versa —
a product in many categories, each category holding many products.
Using relations
The dataset query layer resolves related records for both the editor and screen bindings, so you can render a record together with the things it links to.
Tips
- Point references at a stable model — renaming fields is safe, but restructuring a related model affects everything that references it.
