Relationship between Unified Catalog and Data Map

The Data Map is the technical layer of Microsoft Purview that stores the data about the assets. Data sources are scanned to create the inventory of what assets are available in the different data sources across your organization's data estate.

The Unified Catalog is the business-friendly layer where data stewards curate data, and data consumers find the right data to use. The Unified Catalog is powered by the asset inventory in the Data Map to create a marketplace of data products, ensuring consumers can find the right data and use it responsibly.

Quan trọng

As you work with Data Map and Unified Catalog, keep these points in mind:

• All data in Data Map and Unified Catalog is metadata, not the underlying data itself.
• None of the permissions or roles in Data Map or Unified Catalog provide access to underlying data itself.

Who to involve in data governance

When you start your data governance planning with data owners, data stewards, and other business users with expertise, you'll ensure that the Unified Catalog has all of the information needed to build new value with data. IT teams are critical organizational partners in their data use, and help to ensure the right data sources are prioritized for onboarding to the Data Map.

Your organization's data office will oversee the creation of the catalog with company-wide standards, and help build bridges between teams to provide the best governance framework. Having both the data publishing teams and the data consumers included in the process of building out the catalog will provide the most value from the data, and build the collaboration to include all of the experts across your organization.

For the best success, it's critical to involve all parties early. This is because the practice of data governance isn't done by a single person, and no one knows everything about the data, the business, and what it means to use that data responsibly.

The sequence in which you perform your initial setup tasks might depend on your business strategy and who's doing the work.

Permissions hierarchy

Before you start assigning roles and permissions to users in your organization, it's helpful to understand the relationship between the primary data governance solutions, Unified Catalog and Data Map, and the permissions granted by the roles for each solution.

• Tenant, or organization: Users who own the Microsoft Purview instance and need access to maintain its permissions and information.
• Data Map: Grants permissions to create and administrate technical domains and collections.
• Unified Catalog: Grants users permission to create governance domains or access data estate health.
• Governance domain: Grants permissions for objects within a governance domain, such as glossary terms or data products.

When you're ready to start assigning roles and permissions, Data governance roles and permissions gives detailed instructions. To guide you through the process, we recommend beginng with Getting started with data governance.
