Viewing Lineage and Impact Analysis
The Lineage and Impact Analysis view shows how data flows from data sources to data destinations and through Spectrum™ Technology Platform flows. Lineage and impact analysis are similar concepts that describe different ways of tracing the flow of data.
Lineage shows where data comes from. You can use it to trace the path of data back to its source, showing all the systems that process and store the data along the way, such as Spectrum™ Technology Platform flows, databases, and files.
Impact analysis shows where data goes and the systems that depend on data from a selected data resource. You can use it to view the flows, databases, and files that use a data resource directly or indirectly. Looking at impact analysis is useful if you want to understand how a modification to a database, file, or flow will affect the processes and systems that use the data.
Metadata Insights can show lineage and impact analysis in a single diagram that shows the complete flow of data from source to destination. You can also choose to view lineage only or impact only. By viewing data lineage and impact analysis together you can pinpoint issues in your data processes and plan for upgrades and modifications to your data processes.
The resulting diagram shows the flow of data into and out of the entity you selected. The entity's lineage is to the left of the entity. The entity's impact is to the right. You can change the diagram to show only the entity's lineage or only the entity's impact .
