Hi,

Thank you for contacting us. Yes this is possible from Jotform directly to your database if that is what you were trying to do. Please see this guide on how to setup your form to send to your database http://www.jotform.com/help/126-Form-to-MySQL. We also have webhook were you can use to send data please see this guidehttp://www.jotform.com/help/245-How-to-Setup-Webhook-with-JotForm.  Please let us know if there is anything else we can help you with or if this is not what you were looking for and we will be happy to help.
