CRB-Tree: An Efficient Indexing Scheme for Range-Aggregate Queriesllows: Given a set of weighted points in R., compute the aggregate of weights of points that lie inside a .-dimensional query rectangle. In this paper we focus on range-COUNT, SUM, AVG aggregates. First, we develop an indexing scheme for answering two-dimensional range-COUNT queries that uses. disk

Optimal Range Max Datacube for Fixed Dimensionse . ≤ .. log log ./ log(log* .), our structure requires .(...) query time and .((..n).) storage where .., .. and .. are constants independent of . and .; and log* . is the minimum number of repeated logarithms it takes to reduce the value . to at most 2. Hence our data structure is asymptotically op
