Add relationship to dataset lineage

Manually adding relationships to a dataset lineage visualization involves identifying and linking datasets to reflect their lineage accurately. This process helps in understanding data flow, dependencies, and impact across the datasets.

This functionality helps connect datasets that share common fields or attributes, enabling combined analyses or reports. It only impacts the datasets involved, allowing for relationships that are specific to the context of those datasets.

To add a manual lineage relationship for a dataset:

1. Navigate to Catalog > Datasets and select the specific dataset to which you wish to add manual lineage.
2. Go to the Lineage tab to view the origin card containing information about the selected dataset.
3. Enable Edit-Mode to start building lineage relationships manually.
4. You can hover over the card to view the information within the card. The card itself cannot establish a relationship with another card; only the items within the card can form relationships.
5. Two arrows or + (Add) buttons will appear in both directions. Hover over the arrows to select relationship direction, either downstream or upstream.
6. Select the relationship direction to open the Add Lineage Relationships side panel.
7. A list of available datasets will appear. Select the dataset you want to link to the current dataset. After selecting the desired dataset, click Next to proceed.
8. You will be prompted to select the Relationship Type. Choose the appropriate type (for example, upstream or downstream) based on how the datasets interact.
9. Map the columns that correspond to the selected datasets according to the established relationship types and click Add.
10. The selected fields will get added to the canvas in the chosen direction. Review the lineage diagram to ensure that the new relationship is accurately represented.
