Overview: Defining a Data Model for Customer Data US Tokyo EU01

In Master 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.

Master Segments provides an interface that professionals, who are not database designers or developers, can use to define a data model for customer data. You can use Master Segments to manage, unify, consolidate, organize, and link data from all your Treasure Data tables.

1. Navigate to Data Workbench.
2. Select Master Segments.
3. Click Add a New Master Segment. 

Master Segments gives you an ability to build a single view of a customer, that includes capturing all interactions associated with your brand. 

Within Master Segments, you create a Data Model for your customer data. When the data model is defined, Treasure Data automatically generates a series of logic to unify customer data into one huge flat table.
