Range Sum Queries in Dynamic OLAP Data Cubes

  title={Range Sum Queries in Dynamic OLAP Data Cubes},
  author={Hua-Gang Li and Tok Wang Ling and Sin Yeung Lee and Zheng Xuan Loh},
The data cube is frequently adopted to implement On-Line Analytical Processing (OLAP) and provides aggregate information to support the analysis of contents of databases and data warehouses. Range-sum queries require accessing large data cubes and adding the contents of massive cells immediately. Techniques have thus been proposed to accelerate range-sum queries by applying pre-aggregated specified cells of data cubes. However, this faster response leads to higher update cost and possible need… CONTINUE READING
