| Abstract: | This paper Introduces the problem of data mining assocaiation rules in relational tables containing quantitative and categorical attributes.We adopt the method to fine-partition the value of quantitative attributes and merge adjacent partitions when necessary and introduce the measures of partial completeness to quantify the information loss due to partitioning.Finally, an algorithm for mining such quantitative association rules is proposed. |

| Keywords: | Data mining Quantitative association rules Partial completeness Partition |
