What is business lineage?

πŸ€“ Who can do this? Before you can explore business lineage, you will need your Atlan admin to enable the products module in your Atlan workspace.

Business lineage is a representation of relationships between your data products in Atlan. This simplified view of product lineage can help you quickly grasp the provenance and relationships of your data products and draw links in the chain of your asset universe.

As a map to your data estate, business lineage can help:

  • Data producers understand how their data products are used within the organization.
  • Data consumers gain visibility into the provenance of the data products they use.
  • Both producers and consumers better understand the business relevance and impact of data.

Output ports determine the relationships between your data products. For example, if your data product includes assets that are designated as output ports in another data product:

  • within the same domain or subdomain,
  • across different subdomains within the same domain,
  • or across entirely different domains,

...this relationship will be visualized as business lineage.

The assets designated as output ports in other data products serve as input ports for your data product, automatically linking them based on your asset selection.

Note that you cannot set input ports manually. You can, however, designate output ports while creating a data product or updating the asset selection.

 

To view product lineage:

  1. From the left menu of any screen in Atlan, click Products.
  2. To select a data product, you can either:
    • From the left navigation menu on the Products homepage, use the search bar or select the relevant domain and then select a data product.
    • In the Explore products section on the Products homepage, select a recently viewed, starred, or new data product.
  3. From the tabs along the top of your product page, click the Lineage tab.
  4. On the lineage graph, the home icon indicates the base product. (Optional) Hover over any data product to view a metadata popover for more context β€” including domain name, criticality and sensitivity levels, owner, and product score. You can also open lineage in a new tab.
  5. (Optional) For any applicable product, click the view output port menu to view output ports:
    • The default view shows 10 output ports. Click Show more to view the full list of output ports.
    • Hover over an output port in the list and then click the upward arrow to view lineage for that output port asset in a new tab.
  6. (Optional) To collapse the sidebar, to the left of the sidebar, click the rightward arrow.
  7. (Optional) From the top right of the lineage graph:
    • Click the Find in canvas search bar to search for any specific products on the lineage graph.
    • Click the downward arrow to download product lineage as an image.
    • Click the eye icon to set preferences for the lineage graph:
      • For Additional metadata, show or hide the following context for your assets β€” domain name, announcements, or sensitivity and criticality levels.
      • For Line arrows, show or hide the arrows that indicate data flows on the lineage graph.
    • Click the question mark icon to share feedback.
  8. (Optional) From the bottom right of the lineage graph:
    • Click the minimap icon to view an abridged version of the lineage graph.
    • Click the refocus icon to refocus your view of the lineage graph to reset to the default view, selected node, or back to the base product.
