The meteorological telecommunication system is the hub of transmitting national and international data, in order to grasp the situation of data transmission in the meteorological telecommunication 〖JP〗system, manage the data effectively, optimize and combine the operational service processes, according to the characteristics of the data, a multi dimensional model is constructed with the data of the telecommunication system, and a solution to long time series data is proposed, which uses the SQL Server Analysis Service to launch a pilot run with the data in the real operational environment, and implement the OLAP application, and verify the advantages of the multi dimensional model in data analysis and display.
