Can information from survey be merged into a database?

It is possible to send the form submission to your own MySQL database using PHP. Please refer to this guide: How-to-send-Submissions-to-Your-MySQL-Database-Using-PHP.

You might also want to check JotForm Webhooks. Here's a guide: How-to-Setup-a-Webhook-with-JotForm.

If you are looking for exporting the submissions and then importing them into a database, then you can use these apps: http://apps.jotform.com/search/database.

Hope that helps. If you have any questions, let us know. Thank you.
