The demonstration application shows the use and programming of the Natural Web Interface. The functionality includes simple file maintenance with various selection functions as shown in the graphic below.
The demonstration is platform independent and is based on the Adabas files EMPLOYEES and VEHICLES.
The HTML-GUI has some restrictions for application design:
a unique layout is not possible for different browsers.
the HTML-GUI elements have restricted functionality. For example, no input in selection box, only predefined fonts or buttons for submit (no default button).
So in the demonstration application we use:
forms with submit buttons.
global data exchange with hidden fields on the forms.
usage of the form send back method GET (URL plus visible parameters for bookmarks).
no usage of VB / JAVA Scripts for implementation of processing rules.
a command dispatcher module (D3CHOOSE) for navigation.
standard pictures for group/male/female persons because of copyright reasons.
The demonstration contains one module (see also the installation of the Natural Web Server Extension):

| T3 | HTML text for online documentation |
| E3 | Examples for online documentation |
