After having introduced health information systems in general we will at first turn our attention to hospital information systems (HIS). According to our previous definition of health information systems a HIS is the socio-technical subsystem of a hospital which comprises all information processing as well as the associated human or technical actors in their respective information processing roles. We now take a closer look at what HIS look like. We will do that rather synthetically. This means that we will first look at all the detailed components a HIS consists of and afterwards we will explain step by step how these components can be synthesized, that is, assembled in order to achieve what users nowadays experience as the HIS.
