# Domain separation and CMDB Coverage

Domain separation is unsupported for CMDB Coverage. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data.

## Support level: No support

-   The domain field may exist on data tables but there is no business logic to manage the data.
-   This level is not considered domain-separated.

For more information on support levels, see [Application support for domain separation](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-security/domain-separated-apps.md).
