Abstract

Hospitals are increasingly concerned with the construction of computer-based medical order communication system (MOCS), despite the fact that they are financially being pressed. With limited budget, management in hospitals ought to be pursuing both methodologically effective and technically sound way of constructing MOCS. This paper intends to contribute itself toward better design of database for MOCS with reference to a university hospital. Some structural characteristics pertaining to MOCS are identified in ways of systems approach. Based on those findings, construction methodologies are reviewed and put forward with flexibility to differing requirements of hospitals. Suggestions include the followings. (1) Designing step has to be distinguished among conceptual, logical, and physical design while prototyping for user interface is utilized only for the logical design. (2) Many modeling tools including entity life cycle diagram can be effective for system integration with other units. (3) 3 different types of distributed database servers are recommended.
