This paper presents a structured approach for describing business applications and a programming language that embodies the approach. This language provides business oriented building blocks for formally specifying the applications. The language is the nucleus of a Business Definition System in which users define their problems by interacting with application models in a question-answer mode. © 1974, ACM. All rights reserved.
