Abstract: Data mining deals with finding hidden knowledge patterns in often huge data sets. The work presented in this paper elaborates on defining data mining tasks in terms of fine-grained composable operators instead of coarse-grained black box algorithms. Data mining tasks in the knowledge discovery process typically need one relational table as input and data preprocessing and integration beforehand. The possible combination of different kind of operators (relational, data mining and data preprocessing operators) represents a novel holistic view on the knowledge discovery process. Initially, as described in this paper, for the low-level execution phase but yielding the potential for rich optimization similar to relational query optimization. We argue that such macro-optimization embracing the overall KDD process leads to improved performance instead of focusing on just a small part of it via micro-optimization.
