When building the application's user interface, or front end, the first decision is what overall style the application will have: does it need to look like a typical Windows application, with toolbars, fancy onscreen doodads, and sophisticated online help? In our case, probably not, particularly considering our development budget. Does it need to run from the command line? Almost certainly not. Instead, making the front end web-based—that is, accessible from a web browser like Netscape—makes sense for a number of reasons:

  • Almost everyone in the user community is comfortable surfing the Web, so they should be comfortable with an application they can run from a web browser.
