integrate form to a database

I need a different kind of advance features like auto-post to a database... (excel or sheets is fine) and then I need the ability to pull from that database the data I need to repost it elsewhere (online or e-mail. website)

Mean can it be possible to attach my form to the website database that automatically updates to the website once someone fills the form. It changes the data appearing on my site based on results

I hope i am able to convey my message.

There are two ways on how you can achieve the said requirement.

The easiest way is to integrate your form to Google Sheets. So every time a new submission is received, a copy of the data will also be sent to the integrated sheets.

Or if you are using a MySQL database, you may refer to this guide on How-to-send-Submissions-to-Your-MySQL-Database-Using-PHP. Note that this will require you to create a custom page to post the form data to. Then do some PHP/MySQL programming to do a form to MySQL.
