Both guidance simulation experiment and flight test can produce many data,and the data amount may become very large after a long time.Managing these data based on the analysis requirements from the simulation analyzer has great significance.And how to manage the data related to guidance simulation is a problem to be resolved for the domestic simulation realm.Based on the character of data warehouse that managing a large amount of data,focusing on analyses and supportting decision-making,the data warehouse was introduced into the data management field of guidance simulation,and the system framework for the guidance simulation data warehouse(GSDW) was designed.With consideration of the data character of the guidance simulation system,some research has been done on data preprocessing which is a technical difficulty during the construction of the GSDW,and a kind of data preprocessing model for the GSDW was put forward.This model can supervise the data preprocessing related to the building of the GSDW effectively.
