A rule-based approach to the construction and evolution of business information systems

The authors demonstrate an approach to software development known as RUBRIC, which recognizes that a particular class of system, namely, business information systems, contain a large element of information processing which is dictated by business needs and that these needs will inevitably change. Consequently, RUBRIC separates data from procedure and business policy from operational procedure, and presents explicit models for all of these. This approach thereby maintains the visibility of those parts of a system which are most volatile and subject to change and thereby reduces system maintenance costs
