聚集查询
Examples
- User - defined aggregate queries
用户定义的聚合查询 - Experiments showed that the sketch - based approaches could efficiently provide approximate answers for aggregate queries
合成数据的查询实验表明草图技术能有效地降低估算误差。 - Based on randomizing techniques , this paper discussed how the sketch - based approach estimates approximate answers to aggregate queries
摘要讨论了基于草图的复杂聚集查询的近似处理算法。 - Hierprefixcube retains advantages on computation and organization of prefixcube , and it can directly support aggregate queries on levels of the dimension hierarchy
它不仅保留了前缀立方在计算和组织结构上的优点，又能直接和充分支持维层次级的聚集查询。 - In sigmod , philadelphia , pennsylvania , usa , 1999 , pp . 359 - 370 . 21 shanmugasundaram j , fayyad u , bradley p . compressed data cubes for olap aggregate query approximation on continuous dimensions
此外， pmc还能保证数据立方体中所有数据在查询性能上的均衡性，这是传统的视图级别的部分物化所无法做到的。
