A Web-based and integrated hospital information system

A Web-based and integrated hospital information system (WIHIS), is presented in this paper. WIHIS is a three-tier Web-based system and focuses on medical information instead of financial affairs. It is integrated with workflow engine to automatize the management and supervising of medical business process as well as rule engine to separate business rules from program code. It could use XML as integration media and adopt a top-down integration strategy to integrate heterogeneous electronic medical records distributed in different sources.
