Orthogonal Range Queries in OLAP
2001We study the problem of pre-computing auxillary information to support on-line range queries for the sum and max functions on a datacube. For a d-dimensional datacube with size n in each dimension, we propose a data structure for range max queries with O((4L)d) query time and O((12L2n1/Lγ(n))d) update time where L ∈ {1,..., log n} is a user-controlled ...

Inverse Range Selection Queries
2016On a given sequence \(X=\langle x_1x_2\ldots x_n \rangle \), the range selection queries denoted by Q(i, j, k) return the \(k^{th}\)-smallest element on \(\langle x_ix_{i+1}\ldots x_j \rangle \). The problem has received significant attention in recent years and many solutions aiming to achieve this task with a cost lower than dynamically sorting the ...
