摘要
针对目前企业内部业务系统众多,数据共享性差的现状,利用云计算在海量数据存储和分析方面的优势,提出了一种基于MapReduce的新的数据交换共享的方案。此方案首先描述了MapReduce编程模型;然后再根据云计算平台设计出了一种新的数据交换架构,并在此基础上分析了新系统的业务流程图、时序图和数据存储以及利用MapReduce进行并行的数据处理,讨论了该系统的安全性;最后用实际应用证明了该方案的可行性,对于基于云计算的数据交换具有一定的借鉴意义。
According to the present situation that in enterprises there are many business systems and they are lack of data sharing, a novel MapReduce based data exchange scheme is proposed by using the advantage of clouding computing in massive data storage and analysis. The scheme first describes the MapReduce program- ming model. Then, a novel data-exchange architecture based on the cloud computing platform is designed. Based on the architecture, business flow chart, sequence diagram, data storage and parallel data processing are analyzed and the system security is discussed. Finally the scheme is validated by a practical application and has some reference value in data exchange based on cloud computing.
