View data lineage
Data lineage views are available for technical assets in the catalog source. You can view lineage at the source, target, data set, or data element level.
Data lineage is a visual representation of the flow of data across the systems in your organization. Lineage depicts how the data flows from the system of its origin to the system of its destination.
View source lineage
The lineage diagram at the source or target level shows how data assets refer to and use sources.
To view data lineage at the source or target level, search for and open a technical asset, and then click the Lineage tab.
The following image shows how the MATTER target table of the Google BigQuery source system gets data from the COMPANY source table of the Google BigQuery source system using the Statement at line 10.0 statement after connection assignment:
View lineage at data set level and data element level
The lineage at the data set level and the data element level shows how other technical assets such as files or tables contribute to the selected asset.
Data sets are technical assets that contain sets of data. Data elements are objects downstream of a data set, and are accessible when you expand a data set to the data element level.
View lineage at the data set level
The data set level displays individual sets of data in the data flow.
To view lineage at the data set level, open a technical asset, click the Lineage tab, and then verify that the level is set to Data Set Level.
The following image shows data set level lineage where the MATTER target reference data set gets data from the COMPANY source reference data set before connection assignment:
The following image shows data set level lineage where the MATTER target table gets data from the COMPANY source table after connection assignment:
After connection assignment, the referenced object icons change to specific object icons.
View lineage at the data element level
The data element level displays details of the data set level. At the data element level, you can see the input sources for expressions or commands and calculations or transformations on the data.
To view data lineage at the data element level, open a technical asset, click the Lineage tab, and then verify that the level is set to Data Element Level.
The following image shows data element level lineage where the STATE reference data element of the MATTER reference data set gets data from the HEADERS reference data element of the COMPANY reference data set using the STATE calculation before connection assignment:
The following image shows data element level lineage where the STATE column of the MATTER table gets data from the HEADERS column of the COMPANY table using the STATE calculation after connection assignment:
After connection assignment, the referenced object icons change to specific object icons.
