In order to solve a series of current problems, such as army exercise training data accumulating, conformity and operation, research on army exercise-training data analysis system construction. Based on analyzing current situation of exercise-training data construction, aiming at requirements of source, application orientation and process in exercise-training, establish army exercise-training data analysis system, design system function module, analyze key technology in system researching, and realize exercise-training knowledge accumulating. Analysis results show that the research can provide the foundation for subsequent system design, and has practical guiding significance for improving the informationization level of army military training.
