Medical Data Management in Time-Sharing: Findings of the DIRAC Project.
Ludwig, Herbert; Vallee, Jacques
In terms of examples drawn from clinical and research data files, one of the objectives of this study is to illustrate several factors that have combined to delay the implementation of medical data bases. A primary factor has been inherent in the design of computer software. The languages currently on the market are procedural in nature: they demand the complete definition of a problem before a program can be run on the machine. This is a serious difficulty because medical information -- as opposed to mathematical quantities -- cannot be cast in a definite format, and questions of interest to a potential investigator cannot always be enumerated before the data is acquired. The constraints placed on data retrieval in the environment of a Blood Bank, for example, are such that on-line interaction with short response time is the basic design objective. In order to clarify the problems of interactive data handling in time-sharing under such constraints, a series of five experiments using the Direct Access Project (DIRAC) language prototype is explained.
