5.7 Bibliographic Notes
Efficient computation of multidimensional aggregates in data cubes has been studied by many researchers. Gray, Chaudhuri, Bosworth, et al. [GCB+97] proposed cube-by as a relational aggregation operator generalizing group-by, crosstabs, and subtotals, and categorized data cube measures into three categories: distributive, algebraic, and holistic. Harinarayan, Rajaraman, and Ullman [HRU96] proposed a greedy algorithm for the partial materialization of cuboids in the computation of a data cube. Sarawagi and Stonebraker [SS94] developed a chunk-based computation technique for the efficient organization of large multidimensional arrays. Agarwal, Agrawal, Deshpande, et al. [AAD+96] proposed several guidelines for efficient computation ...
