Aiming at the rehearsal demand in military information system, an efficient and integrated mission rehearsal method based on Spatiotemporal Event Series (SES) is proposed. First the mission expression based on hiberarchy decompounding and materialization strategy by capability was put forward, and then a mission-oriented data application model was advanced for data customization, which minimized the integrative spatiotemporal dataset according to the least demand of battle mission. After that, the event definition model of SES and its data driving pattern were illustrated. Finally the application method was discussed with specific emulation example. The experimental prototype system proved their validity and feasibility. 
