Business Rules Approach to Information System Development

Notwithstanding the arguments in favor or against business rules approach to information system development the fact remains that there are certain types of requirements, which can be best captured in the form of business rules. Once this observation is appreciated the implementation of business rules in applications emerges as the next major concern. This study reports work done in this direction. It proposes a framework that begins with business policies and business rules for a given business process and derives use cases based on the business policies and traces the implementation of business rules and consequently the business policies by the use cases. The framework proposes three systems for implementation of business rules approach. Business system that contains business goals, business policies, and business rules. Operational system that contains actors and interactions and finally system-underconstruction, which contains use cases. In doing so it makes a different interpretation of a use case. It decomposes a use case recursively into use cases, scenarios and states. This study contends that there are only business goals. Business goals become user goal only when user adopts it by becoming a stakeholder.
