Schema Design AEP email addresses from different sources
As a user might have multiple email addresses. And I have two different source databases in each of those the same user might have signed up with a different email address. I have another CRM user identifier that tell me those two emails are the same person.
- Is it better to use a Schema for each source. So I have two separate email fields, with different structure, that do not get merged in the union profile if they are different.
- Or have two separate email address fields in the same schema that then might have the same address. with two imported datasets.
- Or is it possible to import them into an array field into the same schema from two datasets with the array being filled correctly? So 1 email -> array length = 1. Two different emails -> array length = 2
