Multidimensional data mining association rules is an important research direction.In this paper
we propose an efficient algorithm for mining multidimensial association rules
which combine data cube technique with FP-Growth efficiently by constructing a MDPI-tree
the algorithm can explores both inter-dimension and hybrid-dimension association rules.Lastly this algorithm is applied to cross-selling model of mobile communication
and we can verificate the practicality and effectiveness of the algorithm by experiment.
