Data analysis and aid decision-making system

The invention discloses a data analysis and auxiliary decision-making system, which comprises a data port module, a background management module, a decision-making analysis module, a transmission port module and an analysis platform module, and is characterized in that the output end of the data port module is in control connection with the input end of the background management module. The data cleaning module is used for cleaning original data before data analysis, the data volume needing to be analyzed by the system is reduced, the data analysis efficiency of the system is improved, and before data transmission, the transmitted data is subjected to integration processing, subpackage processing and encryption processing, so that the data analysis efficiency of the system is improved. Data are changed into ordered data transmission packets, data leakage in the transmission process is avoided, the safety performance of the system is further improved, a decision analysis module is used for combining a data ana
