Star-Cubing: An Integrating Method

  • D. Xin, J. Han, X. Li, B. W. Wah, Star-Cubing: Computing Iceberg Cubes by Top-Down and Bottom-Up Integration, VLDB'03
  • Explore shared dimensions
    • E.g., dimension A is the shared dimension of ACD and AD
    • ABD/AB means cuboid ABD has shared dimensions AB
  • Allows for shared computations
    • e.g., cuboid AB is computed simultaneously as ABD
  • Aggregate in a top-down manner but with the bottom-up sub-layer underneath which will allow Apriori pruning
  • Shared dimensions grow in bottom-up fashion
