| 摘 要： | 随着数据库技术的广泛应用和发展,产生了数据仓库、联机分析处理等一系列新技术,并且在实践中得以逐步应用.对于不同类型的联机分析处理技术的研究应用,以关系型的居多,而多维型的研究应用相对较少.通过对多维联机分析处理进行的研究可知,维聚集的实现是一个重点,而带层次的维聚集的实现是一个难点.探讨了多维联机分析处理带层次的维聚集的实现,在进行了分析的基础上,给出了类的设计,之后根据算法用代码予以实现,通过实例进行了验证.

| Abstract: | With the extensive application and development of database technology,some new technologies such as data warehouse and online analytical processing are employed in practice gradually.However,most research and applications focus on relational online analytical processing,whereas little work on multidimensional online analytical processing is done.The dimension aggregation is an important issue but it is difficult to address due to the hierarchies.It is introduced the methods and steps of the aggregation implementation on multidimensional online analytical processing's dimensions with hierarchies.Based on the analysis,the design of the algorithms and classes is presented.The algorithms are validated using real cases. |
