| 摘 要： | 在分析了分布式数据仓库数据一致性维护的重要性,以及目前分布式ETL(Extract,transform and load)中存在问题的基础上,针对传统ETL体系结构对分布式数据仓库一致性维护的不足,提出一种新的分布式ETL的体系结构ETLM,并详细描述了数据一致性维护模块(M模块)的设计与实现。ETLM的体系结构免去了分布式数据仓库需要专门进行一致性维护的额外负担,可以更加正确、快捷、高效地支持OLAP。

| Abstract: | In this paper we analysed the importance of data consistency maintenance in distributed data warehouse and the problems in current distributed ETL.Based on that,in order to overcome the deficiencies of consistency maintenance in distributed data warehouse,we presented a new distributed ETL architecture ETLM,and described the design and implement of the module M in detail.The ETLM architecture relieved the extra burden of consistency maintenance the distributed data warehouse had to do,so it was able to supp... |
