| Abstract: | In the Railway Passenger Transport Marketing Aided Decision System（PMDS）, the data transmission was characterized by the real-time acquisition and the great scales. This paper presented a strategy of data transmission, which was based on a variety of methods, such as task configuration, data compression, resume broken transfer and log tables. The presented strategy applied a fast algorithm and a middleware called DBCS（Database Communication Server） to implement data transfer between distributed databases in PMDS. The Application of this strategy could meet the demand of decision making. |
