This research combines information technology in the Standard of Exchange P
roduct model data (STEP) and Internet communication by constructing a user
interface for object-oriented database management system on a world wide we
b (WWW) server. To construct the user interface, we chose an enterprise as
our case system. Then, we analysed the workflow of the case company and the
interface of its database. The database interface was then transferred fro
m a DOS system to a Web system. Finally, the new system was tested and eval
uated. It is shown that the regular business processes can be integrated th
rough Internet communications, but some limitations still exist. In additio
n, some comments and the guidelines for designing the user WWW interface ar
e documented for designers to refer to.
