摘　　要：文章研究和实现了一种分布式的异步事件处理框架(DistributedAsynchronousEventHandlingFramework,DAEHF)。应用开发人员可以基于DAEHF开发异步事件驱动运行的应用程序,DAEHF高效、灵活地为应用开发人员解决了应用程序网络通信的问题,同时还具备通用、易用、任务自动部署等特点,非常适合应用开发人员开发大型分布式应用系统。本文在设计和实现DAEHF的过程中研究使用了设计复用、线程池、异步事件处理、任务自动部署等关键技术。DAEHF已经在中国科学院科学数据库系统平台软件的数据访问中间件中得到初步的应用。In this paper, a Distributed Asynchronous Event Handling Framework(DAEHF) is studied and implemented. Based on DAEHF, application developers can easily construct asynchronous event-driven software. DAEHF provides efficient and flexible network communication solutions for the application software development, and is characteristic of universality, high usability and task automation deployment. DAEHF is very useful especially for the development of large-scale distributed application systems. During the design and implementation of DAEHF, this paper studies and uses such key technologies as design reuse, thread pool, asynchronous event handling, task automation deployment. DAEHF is preliminarily applied in the data access middleware of Scientific Database platform software.
