Which permission level would allow the user to view their data without having access to make changes to the data store object?

The Viewer permission level is specifically designed to allow users to access and view data without granting them any capability to make modifications. This permission is critical when you want to ensure data integrity while allowing certain users to access information for reporting or analysis purposes. By having Viewer permissions, users can see the data they are authorized to access but are restricted from editing it, thus maintaining the security and stability of the underlying data store.

This is particularly vital in environments where data is sensitive or critical to operations, and it's essential to limit change capabilities to only trusted roles. Viewer permissions strike the right balance between access and control, making it the ideal choice for situations where viewing is needed without any risk of unintended alterations to the data.
