 The Data Graph is a semantic layer that represents a subset of relevant business data that you'll use for audience targeting and personalization in downstream tools. Use the configuration language spec below to add models to build your Data Graph. The Data Graph currently supports 4 layers of depth, including the Profile entity. Warehouse schemas are case sensitive, so you'll need to reflect the schema, table, and column names based on how you case them in the warehouse.
