Explanation
To map the data sources to ingest in Adobe Experience Platform, the developer should use the correct Schema type for each data source. A Schema type defines the structure and semantics of a data set. There are two main Schema types that are relevant for this use case: XDM Individual Profile and XDM Experience Event. XDM Individual Profile is a Schema type that describes a customer entity and their attributes, such as name, email, or loyalty level. XDM Experience Event is a Schema type that describes an interaction or occurrence that involves a customer entity, such as product view, purchase, or browse-abandonment. Therefore, the correct mapping is as follows:
* CRM system - XDM Individual Profile. This is because CRM system data contains customer attributes that can be used to create or update customer profiles in Adobe Experience Platform.
* Purchase data from offline store - XDM Experience Event. This is because purchase data contains interactions that involve customers buying products from an offline store, which can be used to enrich customer profiles or trigger journey activities in Adobe Journey Optimizer.
* Website analytics data - XDM Experience Event. This is because website analytics data contains interactions that involve customers visiting or browsing web pages, which can be used to enrich customer profiles or trigger journey activities in Adobe Journey Optimizer. References:
