At present, we have proceeded to extend SQL into a new language called dmFSQL (data mining Fuzzy Structured Query Language) which can be used to solve real problems of Data Mining. In this paper, we present an architecture that permits us to use this language dmFSQL for Oracle© Database. This enables us to evaluate the process of Data Mining at both a theoretical and a practical level. Thus, we use the proposed system to solve a real problem of Direct Marketing Management. We consider that this model satisfies the requirements of Data Mining systems.
