A Marketing Cloud admin is configuring the Marketing Cloud data model for the first time. Journey Builder will be used to personalize the type of messages being sent to customers, based on if there has been an order or not. There are two existing data extensions: Customers and Orders.
‘Customers’ contains information about subscribers including Email Address, First Name, Last Name, Address, and Customer ID.
‘Orders’ contains information about the orders and includes the unique identifier of the customer.
How should Data Designer be configured to allow this data to be used within a Journey decision split?
