摘要：The paper discusses business systems modelling and information systems development from business
rules perspective. The way business rules influence different system models is analysed in the paper. The paper
presents a method to create a whole business rules system model without separating business rules from models
representing other aspects of the system: system structure, behaviour, actor¡¯s roles etc. The paper briefly discusses
business rules represented in UML use case diagrams. A software system implementing the proposed method is
presented in the paper. The paper shortly presents the results of the experiment performed on a use case model of a
textile factory.
