      Description

      There're several disadvantages to create partial cubes only based on static rules:

      • To learn the concept of these rules will bring extra burden to cube admins
      • To achieve a goal cuboid set may need a very complicated set of static rules
      • Cube designers may be not familiar with business related query patterns, resulting in few static rules able to applied
      • Static rules created at first may not correct or user query patterns are changing dynamically

      The goal of cube planner is to reduce effort for cube admins to design an effective partial cube. It owns the following advantages:

      • No sophisticated combination of static rules is needed
      • Allow more dimensions to be included with few static rules
      • Able to adjust a non-cost-effective cuboid set to a cost-effective one based on historical queries
