Electronic forms (e-forms) provide a user interface to data and services, typically through a browser-based interface. E-forms enable users to interact with enterprise applications and the back-end systems linked to them. Web applications, e-government and e-commerce solutions have sparked the demand for better Web forms that support richer and more dynamic interactions than are possible with HTML forms. New e-form applications include XML content identification, multiple data callouts, field-level validation and embedded process logic contained within a secure format that’s often portable.
