Now organizations want to expand the use of the internet to real data-processing such as order-entry, transaction registration and account inquiries. In doing so they find that HTML is not a tool for creating applications, while the traditional character based Telnet sessions do not appeal to the user or do not confirm the image and style that organizations have built by using the world wide web.
Major benefits can be achieved when existing data-processing applications can be integrated with the World Wide Web. An important aspect will be that such applications can be enhanced with windows features such as buttons, icons, drag-listings, radio-buttons and hypertext-help and can be presented with a style reflecting what an organization already uses on the world wide web.
In general this lecture will deal with providing access to applications through the internet, allowing real data-processing with a graphical user interface and client-server capability, independent of the used operating system or application design environment.
