摘要 要在数据仓库中导入档案数据必须考虑导入的速度问题,因此提出了基于客户机/服务器模式的档案数据并行导入的方案。在整个处理流程中,数据整合是实现并行导入的关键步骤,详细描述了历史数据并行整合的方法。最后,通过模拟实验对并行性的性能进行了分析讨论。 When importing archive data into data warehouse,the problem of importing speed is needed to think about. So this paper presents an archive data parallel importing method based on Client/Server mode.In the whole process flow,data aggregation is the key stage to realize parallel importing.The aggregation method of temporal data is described in detail.Finally ,the performance of parallelism is analyzed and discussed via simulation experiment.
