# Add an Entity View Action Mapper data resource to a page

Add an Entity View Action Mapper \(EVAM\) data resource to your page in UI Builder so that you can standardize how the data sources in your components are displayed in your cards and lists.

3.  Open or create a page.

    For more information, see [Manage UI Builder pages and page variants](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/application-development/ui-builder/work-pages.md).

4.  If you do not have any components on your page, add a **Data set** component to your page.
