Tutorial: Export published reference data to a database
This tutorial shows how to maintain reference data in ONE and export it to external databases for downstream applications.
Scenario overview
You maintain a reference table of US states in ONE and need to export the published data to a database that feeds multiple applications. This ensures all systems use the same standardized state codes and names.
What you’ll learn
- 
How to manage reference data records.
 - 
How to publish reference data changes.
 - 
How to create transformations that export reference data.
 - 
How to update source catalog items with published reference data.
 
What you’ll need
For this tutorial, prepare:
- 
Source catalog item: Any catalog item containing reference-type data (for example, product codes, country lists, or status values).
 - 
Reference data table: A corresponding reference table where you’ll manage the authoritative version of this data.
 - 
Database connection: Access to write data back to your source system or data warehouse.
 
Prerequisites
Before starting this tutorial, ensure you have:
- 
Appropriate role on reference data tables:
- 
Owner or Editor role to create and modify reference data tables.
 - 
Approver role to publish changes (if using approval workflows).
 - 
At minimum Viewer role to access table data.
 
 - 
 - 
Working knowledge of data transformations plans.
 - 
Sample data or catalog items to work with.

Step-by-step instructions
- 
Review your source catalog item
- 
Go to your source catalog item that contains the reference data.
 - 
Display the record preview to see the current data structure.
 - 
Note the existing codes, names, or values that need to be managed as reference data.
 
 - 
 - 
Modify the reference data table
- 
Go to Manage reference data > Reference Data.
 - 
Open your reference data table (or create one if it doesn’t exist).
 - 
Add new records, modify existing ones, or delete outdated entries as needed.
 - 
Review your changes in the draft state.
 
 - 
 - 
Publish your changes
- 
Select the records you want to publish.
 - 
Select Publish to make the changes available for downstream use.
 - 
Verify the published status of your records.
 
 - 
 - 
Create a transformation plan
- 
Go to Manage reference data > Transformation plans.
 - 
Create a new transformation plan.
 - 
Configure the input to use the published reference table.
 - 
Add a Database Writer output step.
 - 
Configure the Database Writer to target the original catalog item.
 - 
Set the write mode to Replace to overwrite existing data.
 
 - 
 - 
Execute the transformation
- 
Validate the transformation plan configuration.
 - 
Run the transformation plan.
 - 
Monitor the execution progress.
 
 - 
 - 
Verify the results
- 
Return to your source catalog item.
 - 
Display the record preview again.
 - 
Confirm that the data now reflects your published reference data changes.
 - 
Verify that your added, modified, or removed records appear correctly.
 
 - 
 
Expected outcome
The catalog item now contains the exact data from your published reference table, ensuring consistency across all systems that consume this data.
