In order to solve the problems such as poor integration and application of the data in spacecraft AIT process, this manuscript analyzes the evolution of AIT process data in three dimensions: product structure, time period and development stage from the aspects of data model construction and data integration. We built a multidimensional data model and developed a multidimensional data management system based on product structure. This system takes the product structure as the core, organizes the AIT process data, defines the correlation relationship between different systems and different dimensions, realizes the structured integration of the whole data of AIT process, and generates the AIT process packet.
