# DataModelViewDoesNotExist validation rule

> Validates that all views referenced in the data model actually exist either locally or in CDF. Ensures deployment success.

This rule checks that all views referenced in the data model actually exist either locally or in CDF.

## Why it matters

If a view referenced in the data model does not exist, the data model cannot be deployed to CDF.

## Example

If the `WindTurbine` view is referenced in the data model, but does not exist in the data model or in CDF,
the data model cannot be deployed to CDF.
