Managing users and roles (Data Virtualization)
Data Virtualization has four user roles, which are specific to the Data Virtualization environment. You can grant these roles to existing Cloud Pak for Data users.
To avoid double masking when you use preview in Watson™ services, access control in Data Virtualization is not applied when you preview a data asset (table or view) that comes from Data Virtualization. This happens only when data masking applies to the preview in Watson services.
The preview is subject to the data protection rules and catalog or project access control only.
This means that even though a user does not have access to query an object from Data Virtualization, they might still be able to preview it in a catalog or project if they have access to that catalog or project as well as the data asset.

Data Virtualization roles
- Data Virtualization Admin
- The user who provisions the Data Virtualization
service is automatically assigned the Data Virtualization
Admin role. After the service is provisioned, the Data Virtualization Admin can give other users access to the
The Data Virtualization Admin is considered to be the manager of the Data Virtualization instance and assigns appropriate Data Virtualization roles to Cloud Pak for Data users.
- Data Virtualization Engineer
- Configures the data sources, virtualizes data, and manages access to virtual objects. Users with
this role can create a virtual table or view and grant access to it to users with any Data Virtualization role. By default, every virtual object that is
created in Data Virtualization is private. This privacy
means that in order for a virtual object to be accessed by a user other than its creator, access to
the virtual object must be granted.
Data source administrators are expected to provide access to a user with a Data Virtualization Engineer role before that user can add a data source. Users with this role service and fulfill data requests from Data Virtualization users.
- Data Virtualization User
Data Virtualization users can request access to virtualized data or data in general by initiating a data request. Users with this role can create views of virtual tables to which they have access.
- Data Virtualization Steward
Data Virtualization Stewards can access data in all user tables and views. Additionally, Stewards hold the Db2®
DATAACCESSauthority on the database.
