Stitching is a process that creates relations between database columns that are Column assets in Collibra Data Intelligence Cloud and BI assets representing the same database, specifically between:
- The assets that are created when you ingest Power BI.
- The assets that are created when you register a data source.
The Power BI Harvester collects the Power BI source code and sends it to Collibra for analyzing. The lineage harvester then pushes it to the Data Catalog and creates the relation between Power BI assets in Data Catalog.
At the same time, Collibra analyzes other metadata of data sources that you registered in Data Catalog and creates new relations of the type "Data Element targets / sources Data Element" between Power BI Column assets and Column assets in Data Catalog. It also creates a data flow between data objects, which is visualized in a technical lineage.
Note When you ingest Power BI, you automatically create a technical lineage for Power BI Column assets.
Stitching issues
To stitch assets in Data Catalog to data object collected by the lineage harvester, the Collibra Data Lineage server looks at the full path of the assets in Data Catalog and the full path of Power BI assets. If the full paths match (including for case-sensitivity), the Collibra Data Lineage automatically stitches them.
Tip You can use the Stitching tab page to easily find the full path of assets in Data Catalog and data objects that were collected by the Power BI harvester and the lineage harvester.
