How to delete the local database of my app

Hello Mendix users,   I would like to know how I can delete the local database of my programm. The background story is that i am calling a webservice to write data to an attribute. So every time the user presses a button, the webservice writes data to the attribute. That leads to many entries with the same value. How can I delete the database of my programm?   Cheers

For this, I don’t think you need to delete the database. i believe you are missing a validation check or else a processing microflow.
