Imagine your data has 3 identifiers - Customer ID, Basket ID and Product ID.
These fields can either be Segments or Unique Values when you upload your data to Anna. The easiest way to figure out whether a field should be a segment or a unique identifier is by thinking about how you want to action Anna's answers to your questions.
Where the field should be a Segment
Action: Do you want to be able to trace back to a particular customer, basket or product?
Question to Anna: What are the top 10 Customers/Products/Baskets (Segment) for Sales (Measure)?
Where the field should be a Unique ID
Action: Do you want to count the number of customers/baskets/products?
Question to Anna: How many Customers (Unique ID) purchased a particular Commodity (Segment)?
What if I want to ask both of those questions?
No problem. You can simply duplicate the columns in your data so you can have one column as segment and one as a unique ID. In this example, Customers = Unique Value and Customer Name = Segment.

Where do I find Unique Values in Search?
