Query: The Language of Databases.

Abstract Query languages have become increasingly important as comprehensive medical databases have become a part of the available knowledge base for patient care. As the user community expands and the need for bedside query arises, the requirement for a fast, easy-to-use, interactive query system must be met. This paper describes the evolution of a query language for the TMR database, discusses problems and limitations of the system, and proposes new approaches to the problem.
