This article presents a logical data model which is going to be implemented in a physical environment. We started off by gathering the system’s requirements from the user and presenting them with the use of UML notation. In connection with requirements, the Entity-Relationship (ER) Model for Market Basket Database was elaborated. Next, the model was evaluated in scope of user satisfaction. At the end of this paper, conclusions point out further research plans for developing the decentralized expert system for market basket analysis}, title={Logical database design for market basket analysis}, type={artykuł}, keywords={knowledge discovery, expert system, association rules, market basket analysis}, }
