With the development of networking technology, XML has become a very important data model used for data exchange. But in current XML data cube model, the aggregation query efficiency is a big problem and can only be improved by reducing the join operations between dimension and fact data. This paper proposes a novel data cube model pXCube, which avoids join operation between dimension and fact data by determining unity path with dimension computation, and it can the reduce query cost greatly.
