In response to the actual needs of data exchange with large scale and high frequency, combining with the characteristics of weapon equipment test data, a data cube model of the equipment test system is established. This paper firstly introduces the fundamental concepts of data cubes and basic models, and then analyzes the actual requirements of the equipment test system, and realizes the overall design with the three-level data model conceptual model, logical model and physical model. The data cube provides multidimensional observation angles for equipment test data, meets the requirements of high efficiency data exchange for actual tasks, and provides a good data foundation platform for subsequent data analysis applications.
