Federated Audience Composition - Data Source

@michael_soprano this from AI Assistant:

Data Storage: The Default Campaign database serves as a central repository for storing audience compositions, segment definitions, and other campaign-related data. It provides a unified environment for managing and accessing campaign data without the need to import all of the data from the enterprise data warehouse into Adobe Experience Platform.

I think we are missing some documentation on that specific option from a FAC perspective.
