This paper presents methods used to develop a conceptual model for a patient database forming the centerpiece of a clinical information system under development. Various modeling techniques are discussed using a simplified fragment of the model. A method for mapping the model onto a relational design optimized for single patient retrievals is described. The results section discusses a number of issues pertaining to the flexibility and usability of this architecture.
