Abstract:

For relieving the pressure of mobile communication pivotal power resource, resolving the obsolescence of the hardware equipment, and satisfying the abstraction, transmission and loading of the quantities of business and data, the paper reforms the cloud computing architecture of data marts by the means of distributed computing and virtual technology and ETL（ExtractionTransformationLoading）tools of cloud computing. Through test and application, it showed that the reformed data marts in BASS（Business Analysis Support System）system become finer in data processing and become more balanced,stable,and high eff
icient in data exchange. And the data marts reduce the cost and increase the efficiency of the basic sources.

Key words: cloud computing, distributed computing, virtualization, internet data center(IDC), data mart
