Extensible Storage Structure Based on Multidimensional Hierarchical Cube
Zhao Qing-jian · 2007
As a multidimensional index structure,the multidimensional hierarchical B~+ tree is introduced,on which an expandable multidimensional hierarchical cube(MH_-cube) is set up.With the hierarchical semantics,MH_-cube may perform quick query,data updates and schema update with high efficiency.A theoretical analysis shows that the MH_-cube is superior to other kinds of cubes.
