ABSTRACT This paper describes the framework of knowledge discovery process in sales data and how the active mining system is applied to the data in the real business world by using the domain knowledge. First the framework of the knowledge discovery process in database is reviewed. It is not clear how users construct actual data mining process and use the domain knowledge in the existing model. We propose two-dimensional matrix of knowledge for sales data analysis to understand knowledge discovery process from purchase history. We distinguish data mining process from creation of business action. We point out that efficient knowledge discovery can be achieved by intensively introducing domain knowledge of experts to the creation of business action.
