摘　　要：应急指挥系统需要一种针对性的技术架构来实现其特有的对实时变化事件的及时响应和高速数据处理。事件驱动的面向服务的框架(SOA)将面向服务的架构和事件驱动相结合,形成一种改进型的集模块化、松耦合、可伸缩、即时响应和适应性等特性为一体的软件架构设计,克服了传统的面向服务的框架所缺乏的实时动态处理缺陷,能有效的应对应急指挥系统的运行特点。基于事件驱动的SOA设计的系统对比传统SOA设计的系统,响应时间缩短44%,事务处理量提升50%。Emergency command system requires a special technical architecture to respond to changed events in real-time and handle data faster. The combination of Service Oriented Architecture （SOA） and event-driven mechanism invocates a new kind of improved architecture, event driven SOA, which has modularization, loose coupling, scalability, instant response and adaptability as a whole, and overcomes the defect of the traditional SOA which lacks real-time processing. In the comparison experiments with the traditional SOA, event driven SOA decreases response time by 44% and increases transaction processing by 50%.
