文档介绍：某小型公司内部管理系统的设计
摘要
网络通讯在当今已经不算新鲜事物,上的服务器,这就给那些具有大规模内部网络的用户造成了许多问题,如浪费网络资源、遭遇到网络攻击、传播的病毒、破坏防御系统等等。由于互连网上的网络通讯工具给企业内部信息交流带来了不便,所以为了方便内部网络的用户之间的沟通,需要开发一个基于局域网的信息收发系统的即时通讯工具,实现在内部网络中进行信息的交流。本课题设计主要针对局域网通讯而开发设计的,采用的是C/S构架,利用Delphi编程工具来实现单播、广播以及在线用户显示和查看历史记录的功能,并借助一些网络通讯组件,成功的实现了在局域网上的即时通讯。本论文共分为六部分。第一部分是课题的背景及研究意义;第二部分是所运用的理论基础知识;第三部分是本系统的需求分析;第四部分是系统结构和模块设计;第五部是实施和测试情况;最后是本设计的结论总结及部分参考文献。

The Design and Implementation of Receiving and Sending Information System Based On LAN
Abstract
munication in already did not calculate the new things now, but the munication all needed to draw support from on the server, this gave these to have the large-scale work user to create many problems, like work resources, bitter experience work attack, dissemination virus, destruction defense system and so on. Because on the munication facilities the munication have brought inconveniently for the enterprise, therefore in order to facilitate work between user'munication, needs to develop one based on the local work information receiving and dispatching system instant message facilities, realizes carries on the information in the work the exchange. This topic design mainly aims at the local munication to develop the design, uses is the C/S structure, realizes the unicast, the broadcast as well as the online user demonstration and the examination historic record function using the Delphi programming tool, and drew support from munication module, the ess realization on the local work instant message. The present paper altogether divides into six parts. The first part is the topic background and the research significance; the second part is the rationale knowledge which utilizes; the third part is this system demand analysis; the fourth part is the system structure and the module design; fifth is the implementation and the test situation; finally is this design conclusion summary and the part reference.
