Object-oriented modeling of hospital information systems.

We have chosen an object-oriented approach for the modeling of a hospital information system; this avoids some disadvantages of the classic methods (i.e., a combination of Structured Analysis and Entity-Relationship-Model). The primary goal of this procedure was to find and represent the needs of communication in the computer-based part of the information system and, with that, to configure an information server that handles all the interactions. Furthermore, we wanted to develop communication interfaces for the application programs on an object-oriented level.
