【摘要】 在一个分布式多层应用系统中 ,如果不注重数据处理的效率 ,将会严重影响系统性能 ,甚至导致系统崩溃。在移动公司研发的“用户离网分析与业务流处理系统”中 ,从优化 SQL语句、采用中间件技术、数据的并行分割等三个层次实现了海量信息集成的优化策略 ,有效提高了系统的时间和空间性能。可见只有研究海量信息系统的特点及规律 ,设计高效的算法 ,才能实现具有可扩展性的系统。更多还原

【Abstract】 In a multi-layer distributed application,the efficiency of the data process should be paid attention to,otherwise the system would run badly,and even breakdown.In the MIS of mobile company named “Analysis of Customer Churn and Supervision of Business Process”,the method of improving the software efficiency with massive information in three degrees is introduced.The method is to optimize SQL,to use Middle-Component and to adopt the Parallel Process.Only when we research the character and rule of the software with massive information,and give a highly-efficient arithmetic,could a flexible management information system be realized.更多还原
