After a user has created a semantic model, you, as an administrator, can review, approve/reject, and deploy it. Only after deploying the semantic model is a materialized view created.

​
Prerequisites

  • Appropriate permission: nx1_semantic_admin
  • An existing semantic model having a draft status

​
Review and deploy a semantic model

Perform these steps to review and deploy a semantic model.
  1. Log in to NexusOne.
  2. On the top navigation bar, hover your mouse over Catalog & Models and then select Semantic Models.
  3. Scroll through the table and click the three dots, ..., at the right on your selected semantic model.
  4. Click Submit for Review.
  5. At the top of the table, click Pending Reviews.
  6. Scroll through the table and click Review on your selected semantic model.
  7. To approve or reject the semantic model, do one of the following:
    • Enter a review note stating the reason for rejecting the semantic model and click Reject.
    • Click Approve to approve the semantic model.
  8. Click All Models.
  9. Scroll through the table and click your selected semantic model.
  10. Click Deploy, then do one or more of the following:
    • Toggle the Register in DataHub button to register the deployed view for discovery.
    • Toggle the Add Lineage button to track data lineage from source tables in DataHub.
    • Toggle the Create Dashboard button to create a Superset dashboard.
    • Toggle the Schedule Refresh button and then enter a cron schedule to create an Airflow DAG for periodic refresh.
  11. Click Deploy.
After deploying the semantic model, NexusOne creates a materialized view. Depending on your preferred selection in step 10, visit DataHub to see the data lineage of the materialized view, or Superset to view the materialized view’s dashboard.
