Learn about data observability in Unified Catalog (preview)
Note
Data observability (preview) in Unified Catalog is now rolling out and may take time to appear in your Microsoft Purview tenant.
Data observability in Microsoft Purview Unified Catalog provides a bird's eye view into the health of the data estate as data flows between sources. The data stewards, experts, and those accountable for data health can view their data estate in a single screen, providing the ability to view the lineage of data assets all the way up to the structure of the governance domains. This single view helps users understand where data starts and ends, what the issues are, and where there's an effect on reporting obligations.
How data observability works
The visualizations in data observability bring together all of the metadata from Microsoft Purview Data Map, for things like technical data lineage, and from the Unified Catalog, for things like data quality. Data observability provides contextual views and on-demand custom views in a single diagram.
Having the right view of the metadata in a single place allows you to dig into questions about how data quality is changing across your data estate, and how your data's being used and by whom. Viewing the entire data estate at one time enables the central data team or federated data teams to quickly identify improvements in metadata, ownership, data quality, or data architecture.
Note
Data observability doesn't create any of the lineage or metadata used in the visualization. If you haven't added lineage, or haven't yet created governance domains and business concepts, the screen will have a limited amount of the data estate to view.
Where observability shows up in Unified Catalog
You'll see an Observability tab when you look at a details page for a governance domain, a data product, and a glossary term. Also, the Data observability (preview) page under Health management in the left navigation provides a custom view of your entire data estate. See Observability views for details.
Note
Certain roles are required in order to see and work with data observability. See Unified Catalog roles for details.
