CubiST++: Evaluating Ad-Hoc CUBE Queries Using Statistics Trees |
2003 |
2276 |
We report on a new, efficient encoding for the data cube, which results in a drastic speed-up of OLAP queries that aggregate along any combination of dimensions over numerical and categorical attributes. We are focusing on a class of queries called <... |
CubiST: A New Algorithm for Improving the Performance of Ad-hoc OLAP Queries |
2000 |
2291 |
Being able to efficiently answer arbitrary OLAP queries that aggregate along any combination of dimensions over numerical and categorical attributes has been a continued, major concern in data warehousing. In this paper, we introduce a new data struc... |
Efficient Evaluation of Sparse Data Cubes |
2004 |
3857 |
Computing data cubes requires the aggregation of measures over arbitrary combinations of dimensions in a data set. Efficient data cube evaluation remains challenging because of the potentially very large sizes of input datasets (e.g., in the data war... |
Evaluating holistic aggregators efficiently for very large datasets |
2004 |
2251 |
In data warehousing applications, numerous OLAP queries involve the processing of holistic aggregators such as computing the “top n,” median, quantiles, etc. In this paper, we present a novel approach called dynamic bucketing to efficiently evaluate ... |
