Stitch the Tableau logical data layer and the Data Catalog physical data layer
You can stitch Tableau's logical data layer and Data Catalog's physical data layer to represent the lineage from the data source to the Tableau reports.
Prerequisites
- You have prepared Tableau's logical data layer.
- You have prepared Data Catalog's physical data layer.
Steps
- Open the Tableau Data Model asset page.Tip You can use the Search to quickly find the relevant asset.
- In the upper-right corner, click Stitch.
The Stitch with data source dialog box appears. - Enter the required information.
Field Description Data Source The Database asset that you want to stitch to this Data Model asset. Filter suggested assets by organization
Option to filter the suggestions based on selected communities and domains.
If this option is selected, the organization tree appears. You can then filter and select domains and communities.
- Click Stitch.
If a relation exists between the Tableau Data Model and the corresponding Database asset, of the "Technology Asset source system for / source system Data Asset" type, stitching happens immediately after clicking Stitch, without showing the dialog box.
This occurs if you created the relation manually, or if you restitch.
What's next?
Stitching is performed, creating relations between assets of Data Catalog's physical data layer and those of Tableau's logical data layer.
More precisely, these relations are created:
- A relation of the type "Technology Asset source system for / source system Data Asset" type between the Database asset and the Tableau Data Model asset.
- Relations of the type "Data Element targets / sources Data Element" type between the Column assets and the Data Attribute assets, based on the full names of the assets.
Tip You can view the stitching result as a diagram.
