I'm curious about the principle of Daas Lead / Account Enrichment.
I have checked the doc below related to Daas.

Before sending out the Eloqua email campaign, I understood that the Daas Enrichment feature enriches the customer's information.
I wonder how this Daas Enrichment works.
If so, it means that the information that fits the customer data in Eloqua is in Daas, so do I have to upload and manage the data that I have in Daas myself?
Or, is there a lot of account information in Daas like Salesforce and can be used in Eloqua using that information?
Also, when Daas Enrichment is working, what is the key value of the enrich target? Is it an email address or something else?
