In this paper, we implement a large-scale data cube computation based on distributed parallel computing using the MapReduce (MR) computational framework. For this purpose, we developed a new algorithm, MRDataCube, which incorporates the MR mechanism into data cube computations such that effective ...
For a data cube there are always constraints between dimensions or between attributes in a dimension, such as functional dependencies. We introduce the problem that when there are functional dependencies, how to use them to speed up the computation of sparse data cubes. A new algorithm CFD is ...
Data cube computation is an important problem in the field of data warehousing and OLAP (online analytical processing). Although it has been studied extensively in the past, most of its algorithms are designed without considering CPU and cache behavior. In this paper, we first propose a cache-...
