Interactive HTML:


Users can provide feedback or use HTML to access databases through forms. Forms can be constructed from five level 2 HTML tags: They provide a user with the ability to enter information which can then be processed on the server as survey information, search information for a database, information request, etc.

Forms by themselves only allow data entry. They require software commonly referred to as gateways, which receive the data, process it, and return a response to the WWW client. Gateways are custom applications written in an available programming language on the server (such as Perl or C). Some gateways are available on the Internet for Z39.50, WAIS, and mail forwarding. Some authors use Javascript to implement client-side form processing.
