Smart files: a method of managing non-deterministic data for multi-tasking and distributed systems

The development of clinical data base structures frequently presents a situation in which the number and type of data items are highly variable or entire data structures require modification over time. Traditional approaches to handling such non-deterministic data (e.g., leaving space for expansion, redefining items no longer used, etc.) have frequently proven to be restrictive and occasionally counter-productive. Modern multi-tasking computer systems provide an environment in which alternative and flexible data base methodologies are possible. "Smart files" have been developed in our institution to provide a means by which many loosely related computer-assisted functions may access distributed data structures while maintaining independence of the physical implementation of those structures. Secondary benefits of this approach include the ability to distribute data across multiple computer systems and the ability to control access to individual data items being used by multiple functions.
