Database validation
Database validation checks the validity of the database schema, and whether form attributes match their data type in the database.
The system validates the database when you import, upgrade, and export templates. When you export templates, only forms that are not linked to any template are validated.
When you import and upgrade, you can save templates even if they are invalid. You receive a warning, but you can still save. However, when you add a form, you cannot save the form if validation finds any errors.
