Optimal Histograms for Hierarchical Range Queries (Extended Abstract)

Summary: Shows equality-optimized histograms are suboptimal for hierarchical range queries in OLAP and casts histogram design as expected-error minimization under a space budget. Presents polynomial-time DP algorithms for one-sided (V-Optimal runtime), balanced-tree, and general hierarchies with provable optimality and empirical error reductions.
