# Create a data domain

A data domain is a collection of information objects. Relate an information object to the database catalog of a database instance to collect the physical data. ServiceNow
Discovery finds the database catalog that lists all the catalog objects, or databases, discovered for an instance of a database.

## Before you begin

Important:  
Starting with the Xanadu release, the data domains module is moved to the Enterprise Architecture Workspace. To learn more, see [Manage data domains](https://www.servicenow.com/docs/928tWbjfNIbIrgvebd3DLQ "A data domain is a collection of information objects. A data domain categorizes information objects.").

Role required: sn_apm.apm_user

Although an Enterprise Architecture user (sn_apm.apm_user) can create a data domain, the access control on the Data Domain \[sn_apm_data_domain\] table is limited to its different users.

* The Application Portfolio Analyst and Application Portfolio Administrator with sn_apm.apm_admin role have create, write, and delete privileges.
* The Application Portfolio User with sn_apm.apm_user role has read access only.
