Duodata Snowflake Native App

Deploy and maintain semantics.

Bring business meaning, physical schemas and open models into one engineering workflow. Deploy native semantic views in Snowflake and metric views in Databricks.

The Snowflake Native App produces Snowflake semantic views used by Cortex Analyst, inside your Snowflake account.

Workflow

Observe, connect, refine, deploy, maintain.

  1. 01

    Observe

    Inspect physical tables, columns and relationships in your platform.

  2. 02

    Connect meaning

    Map business definitions to their physical implementation.

  3. 03

    Refine

    Resolve the platform details that make a semantic model usable.

  4. 04

    Deploy

    Produce the native semantic artifact for your selected platform.

  5. 05

    Maintain

    Review changes to definitions, schemas and their mappings together.

Already have Ossie models? Start with the Native App in your platform, then connect Duodata's business definitions when your team needs shared ownership and meaning.

Maintain

A schema change, reviewed

Rename the physical gross column and see the one affected mapping. Only Update mapping changes the native output; the business definition and totals stay the same.

Mapping and native output match the observed schema.
