事件驱动体系结构在GIS中的设计实现

Design and Implementation in GIS of Event-driven Architecture

随着地理信息系统的发展和应用,其规模和复杂度日益增加,难以并行开发、方便测试发布、良好扩展等问题日益突出.本文依据实际系统开发,提出了基于事件驱动风格的体系结构,针对该体系结构创建了虚拟窗口的概念,并给出了系统具体实现的方法.通过该体系结构,可以降低类似系统的开发难度,提高软件开发速度、方便软件测试以及发布工作.

With development and application of Geographic Information System (GIS),its scale and complexity increase quickly and the problems of developing concurrently,test and deploy,extendibility become to be more protruded.According to the development of real system,the present paper brings forward event-driven soft architecture.Aiming at this architecture,the concept of virtual windows was created and the concrete implementation method was displayed.This method can reduces the difficulty of soft development and increases development speed,make soft testing and deploy conveniently.
