# Add or edit a data domain from the Portfolio page

Create or edit a data domain to relate an information object to the database catalog of a database instance to collect the physical data.

## Before you begin

Although an Enterprise Architecture user \(sn\_apm.apm\_user\) can view a data domain, the access control on the Data Domain \[sn\_apm\_data\_domain\] table is limited to its different users.

-   -   The Enterprise Architecture analyst and Enterprise Architecture administrator with sn\_apm.apm\_admin role have create, write, and delete privileges.
-   The Enterprise Architecture user with the sn\_apm.apm\_user role has read access only.

Role required: sn\_apm.apm\_admin

## Procedure

1.  Navigate to **Workspace** > **Enterprise Architecture Workspace**.

2.  Open the Portfolio List view by selecting the Portfolio icon \[Omitted image "portfolio-icon.png"\] Alt text: Portfolio icon.

3.  Select the expand row icon \(\[Omitted image "ExpandIcon.png"\] Alt text: Expand Row icon\) next to **Information Portfolio**.

4.  Select **Data Domains**.

5.  Add or edit a data domain.

    -   To add a data domain, select **New**.
    -   To update details of an existing data domain, select the data domain.
6.  On the form, fill in the fields.

    For field information, see [Data Domain form](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-portfolio-management/eaw-data-domain-form.md).
