摘要 针对Data Cube的模式变动造成的多版本问题,对时态聚集关系与时态层次链进行了形式化描述,并基于这些关系实现了多个版本的Data Cube的统一生成算法,不仅可以高效地进行Data Cube多个版本的维护,而且在OLAP查询也可以基于时态层次链来执行,从而提高系统的整体效率。 This article first gives formalization definitions of temporal aggregation relation and temporal hierarchy chain for solving the data cube＇s multi-version problem caused by pattern＇s changes.Then a uniform algorithm for generating the multi-version data cube is proposed.It cannot only maintain the multi-version data cube effectively but also optimize the OLAP queries based on temporal hierarchy chains and thus the efficiency of system is improved.
