What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
You can create an auto-responder and insert an edit link, so that when your customers submit the form, they receive a copy of the form with an edit link that allows them later to edit the information of the form:
For the database it depends on your needs and the degree of complexity you want. You can simply choose a Google Spreadsheet integration that will store all the submitted data or you can choose more complex solutions, like the ones here.
But please share more details on your needs so we can find the best solution for you.
Let us know if further support is needed.
