title: A simple client-server system using a personal computer as the server.
abstract: Hospital information systems have recently grown into huge, complex systems. As a result, the cost of development and maintenance of application programs has increased and become a serious problem. We have constructed an order entry system using server-client architecture as part of a hospital intranet information system in which a personal computer is used as a server. Using a commercial database management system and software development tools, an easily maintained order entry system was developed within only three months by one programmer. Since slow response when the number of clients increased was possible, we measured turn-around times when one or ten clients accessed simultaneously. Turn-around times were 8 and 10 sec, respectively. Because we expect much better performance from personal computers in the near future, application systems using personal computers as Intranet servers will be cost and time effective and easy to develop and maintain.
