ServiceNow intentionally abstracts from the database layer, so that admins and developers never have to touch the database.
All your design and configuration should take place at a higher level. The benefit of the ServiceNow platform is that you do not have to think about databases and other technical artifacts and can concentrate on your business processes and data model
Therefore, direct access to the database layer is not possible. If there are any issues with the database, these will be handled by ServiceNow technical support and cloud administrators, so you don't have to worry about that.
