（ 摘 要 牌号系统是为解决一些服务业营业大厅排队问题而设计的，它能够有效地提高工作人员的工作效率，也能够使顾客合理的安排等待时间，让顾客感到服务的公平公正。 论文首先讨论了牌号系统的背景、意义、应用现状以及研究与开发现状。本文在对C/S架构、Socket网络编程技术、Java线程编程等相关技术理论做了简单的论述。结合工程项目，具体论述了牌号系统的需求分析、整体设计以及系统数据库的设计，其中包括业务流程图、系统用例图、功能结构图、数据流程图、以及系统数据库的E-R图的分析和描述。 其次，论文着重讨论了C/S架构的牌号系统的设计和实现。在论文中详细地论述了牌号系统的数据库设计与系统实现的各个步骤，并对原型系统作了简要介绍。 最后，论文对主要完成的工作进行了总结，并提出了研究的不足之处以及对今后研究的展望。 关键词：C/S架构；Java多线程；牌号系统；Socket网络编程；开发 Abstract Grade system is designed to solve problems of queuing in Hall of bussiness services. It can effectively improve the staffs efficiency, and make the customers reasonably arrange the waiting time, then supply fair and just service for the customers. Firstly, background, significance, development and application of grades system were discussed in this paper. The C/S structure, Socket network programming technology, Java-thread programming, and other related technologies were also simply dissertated. The requirements of the trademark system analysis, system design and database design were well-documented, which included the operational flow chart, the system use case plans, functional structure, data flow chart, and the ER system database analysis and description of the plan. Secondly, the design and implementation of C/S structure was discussed in this paper, which mainly concerned the design of database system, the various steps of the Grade system, and the introduction of prototype system. Finally, the main conclusion was summarized in this paper. Moreover, the inadequacy of this study was suggested as well as the prospects for the future research. Keywords: C/S structure; Java multi-threaded; grade system; Socket network programming; development目 录 引 言 1 第一章 系统分析 2 1.1 系统初步调查 2 1.2 系统可行性分析 2 1.2.1 经济可行性 2 1.2.2 操作可行性 2 1.2.3 技术可行性 2 1.3 系统开发环境概述 3 1.3.1 硬件环境 3 1.3.2 软件环境 3 1.4 系统需求分析 3 1.4.1 业务流程分析 3 1.4.2 系统体系结构设计 4 1.4.3 系统逻辑模型 4 1.5 系统需求定义 5 1.5.1 客户用例图 5 1.5.2 业务员用例图 5 第二章 系统总体设计 7 2.1 系统设计目的与任务 7 2.2 开发设
