Research of data cubes computation based on joint relation set

摘要

Data cubes is the base of OLAP and OLAM. The traditional algorithms can transfer only one relation table to data cubes at the same time and have no choice but compute the data cubes one by one for relation set composed of several tables. A new algorithm of data cubes computation based on joint relation set is raised in this paper to save the construction time and storage spaces, which is more efficient than the traditional algorithms under the verification of experiments.
