When relationships are defined during the customization step, Forest Admin Collections act as if the 2 Collections were natively linked at the data source level.
You may have noticed that relationships within a data source are configured out of the box, so you won't need to define those.
However, you may want to create additional intra and cross data source relationships to:
- help users navigate within your admin panel,
- create charts that use data from multiple data sources,
- let users filter, use scopes, or segment with conditions that cross data source boundaries.
