 To start seeing unified profiles in your warehouse and build attribution models, you'll need to materialize the tables that Profiles Sync lands into three key views:
 
   * `id_graph`: the current state of relationships between segment ids
-  * `external_id_mapping`: current-state mapping between each external identifier you’ve observed and its corresponding, fully-merged `canonical_segment_id`
+  * `external_id_mapping`: the current-state mapping between each external identifier you’ve observed and its corresponding, fully-merged `canonical_segment_id`
   * `profile_traits`: the last seen value for all custom traits, computed traits, SQL traits, audiences, and journeys associated with a profile in a single row
 
 Please visit [Tables you materialize](/docs/profiles/profiles-sync/tables/#tables-you-materialize) for more on how to materialize these views either on your own, or with [Segment's open source dbt models](https://github.com/segmentio/profiles-sync-dbt){:target="blank"}
