In response to the problems of decentralized management and insufficient utilization of launch data for rocket testing,a data warehouse technology is proposed to organize and store the test and launch data of rockets,achieving the deep exploration of the rocket data.According to the characteristics of the carrier rocket data,it proposes six levels of framework design such as the data warehouse foundation layer,source data layer,data interaction layer,data architecture layer,application layer,and display layer;The different sources and format data are cleaned and loaded by the data cleaning rule design for the rocket data analysis and fault di-agnosis;The direction of rocket data application is explored,which designs data analysis modules such as the envelope analysis,cor-relation analysis,and fault diagnosis.The validation is conducted using launch data from a certain type of rocket,and the results show that the data warehouse solution is feasible,and it provides a foundation for the continuous management and analysis of the rocket da-ta in the future.
