Defining a data model for customer data is done by defining parent segments. Parent segments give you an ability to build a single view of a customer, including capturing all interactions, such as attributes and behaviors associated with your brand. In parent segments, you unify your customer data. When the customer data is unified, you can create customer segments without writing any SQL queries. You can personalize customer communications and conversations of any size and in any channel.
Treasure Data is making an effort to use more inclusive language in its product, content, and customer solutions. As we gradually make the move to replace insensitive language beginning in our UI, you may continue to see parent segments in the UI, for example, referenced as master segment in portions of Treasure Data APIs.
