Abstract:

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 programming 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.
