基于构件技术的信息管理系统的设计与实现

摘要

The available information management systems have simple working mode,low working efficiency and low sys-tem functional requirement of users. To solve the above problems,an information management system based on component tech-nology was designed. The system is composed of two foreground components(task log processing module and login administra-tion module)and three background components(information resource monitoring module,user task management module and in-formation overload management module). The background components receive the information of the foreground components to configure the components. The sub-modules of the five functional modules and their working contents are introduced. The working principle of the foreground components was designed. The JGroups group communication tool is used to define the information structure standard format of the background components. The code of the information management program is given to manage the information effectively. The experimental results show that the designed system has good resource allocation effect,and satisfies the high system functional requirement of the Internet users.%现有的信息管理系统工作方式较为单一,工作效率低且用户对系统的功能需求度不高.为了解决该问题,设计基于构件技术的信息管理系统.该系统由任务日志处理、登录管理两个前台构件主功能模块和信息资源监控、用户任务管理、信息超负荷管理三个后台构件主功能模块组成,其中后台构件对前台构件的信息进行接收,完成构件配置,并介绍了五大功能模块的子模块及其工作内容,设计出前台构件的工作原理,并使用JGroups群组通信工具定义后台构件的信息结构标准格式,给出信息管理程序代码,实现了有效的信息管理.实验结果表明,设计的系统资源分配效果好,满足了网络用户对系统功能的高度需求.
