Online form
A web page that collects structured answers from respondents.
An online form is a digital document that gathers information through fields - text, choices, ratings, uploads - and stores each submission as a structured response. Unlike a paper form or a flat document, every answer lands in a database row keyed to a stable question id, which makes the data queryable, exportable, and safe to analyse over time.
Modern online forms add logic, theming and analytics so they behave less like static documents and more like small applications. A registration form might branch based on a job title, pipe the respondent's name into a confirmation screen, and fire a webhook to a CRM the moment it is submitted.
The quality of an online form is mostly invisible: how it validates input, how it handles partial submissions, whether it is accessible to keyboard and screen-reader users, and whether you can get your data back out cleanly. Those properties matter far more than the visible styling once a form is collecting real responses.
