# Panel Updating

## ✒️ **Panel Updating**

Using panel updating along with the panelist mapping features you can display to the currently [logged in](/form-management/security/security-items/panel-security.md) panelist all the data that you have stored about him in our panel. The respondent can then update that information which will be pushed back to your panel once he submits his survey.

In the case of the [SQL Server connector](/panels/panel-connectors/sql-server-connector.md) you setup ngSurvey to update the linked table with the newly entered information from the survey.

{% hint style="info" %}
Panel updating requires that the [panel security item](/form-management/security/security-items/panel-security.md) is activated on the survey to authenticate the [panelist](/panels/panelists.md) to lookup the data that should be shown to the respondent for update..
{% endhint %}
