C语言课程设计-网吧管理系统

《通信工程专业C语言课程设计》报告专业：通信工程班级：0802姓名：赵松指导教师：丁雄二00九年十二月二十五日目录一、课程设计题目及所涉及知识点 (1)二、课程设计思路及设计流程图 (1)三、课程设计中遇到的难点及解决办法 (4)四、小结 (4)参考书目 (6)附录原程序 (7)一．课程设计题目及所涉及知识点(一).课程设计题目：网吧管理系统(1).基本内容网吧管理系统管理信息包括会员的会员名、性别、年龄、积分等。

试设计一网吧管理系统，使之能提供以下功能：系统以菜单方式工作，密码登陆。

1．会员信息的录入（增加数据）。

用数组数据类型赋初值的方法把会员信息送到各个数组中（但要注意是合法数据），然后把它们保存起来。

2．会员信息的删除（删除数据）。

任意输入一位会员号，将它所有的信息从组数中删除。

3．会员信息的浏览（查找数据）。

任意输入一位会员号，打印出他的所有数据。

要求能多次查找。

4．会员积分的计算（积分数据）。

任意输入一位会员号，打印出会员的积分。

要求能多次积分计算。

5．会员管理系统登陆。

输入密码登陆系统。

(2). 课程设计的要求与数据1．编程时，设计函数来完成每个功能，通过main函数调用各函数。

2．程序中的输入输出要加提示说明。

3．输出的结果要准确、清晰、美观。

(二).所涉及知识点：结构体数组的定义与引用;函数的定义与调用;局部变量和全局变量; for循环语句;指针；if语句;switch语句;break语句;格式输入与输出；字符串处理函数;函数的定义;数组作为函数参数.二、课程设计思路及设计流程图1、课程设计思路根据题目的要求，需要一个主程序main()和12个子程序，分别为quit（）、loading（）、menu（）、input（）、save（）、load（）、list（）、window（）、add（）、del（）、search（）、point（）；可以实现退出、登陆、菜单、输入、保存、导入、列表、界面、增加、删除、查找、积分。

网吧计费系统数据库设计

网吧计费系统设计文档1、oracle数据库设计fee int not null --费用--)--为records表创建主键--alter table records add constraint PK_tb_records primary key(id)--为tb_record表创建外键--alter table records add constraint FK_caIds foreign key (cardId) references cards (id)alter table records add constraint FK_coIds foreign key (computerId) references computers (id)--为records表创建序列--create sequence re_seqstart with 1 --设置序列的初始值--increment by 1 --每次增长1--maxvalue 10000 --设置序列的最大值为10000--minvalue 1 --设置序列的最小值为1----为records表创建触发器，让主键id自动增长--create or replace trigger re_tribefore insert on records --触发条件：当向表执行插入操作时触发此触发器--for each row --对每一行都检测是否触发--begin --触发器开始--select re_seq.nextval into:new.id from dual; --触发器主题内容，即触发后执行的动作，在此是取得序列dectuser_tb_seq的下一个值插入到表中的id字段中--end;四、用Java分别编写三个DAO：CardsDAO.java、ComputerDAO.java、RecordDAO.java（增删查改这四个方法）。

五、整合相关代码六、调试程序，看是否有错。

网吧计费系统附完整源代码

简易的网吧计费系统设计设计一个简易的网吧计费系统，要求上网人输入卡号和密码上机，卡号或密码不正确，不能上机，卡余额不足不能上机；正在使用的机器不能被再使用；上机需要记录卡号、机器号、上机时间；下机时需要记录下机时间、发生费用和自动从卡里扣款，该机器能再被使用；下机时，需要向用户显示本次上机的详细信息。

1) 上机业务流程卡号和密码的校验；卡的余额的检验；获取当前系统时间作为上机开始时间；记录上机操作；修改该机器的使用标志2) 下机业务流程选择被使用的机器号；获取系统当前时间作为下机时间；计算费用；扣费；记录下机时间和此次费用；修改该机器的状态为可用结构图效果截图如下********************face类********************* package

20世纪50年代，西蒙提出管理依赖于信息和决策的思想。

同时期的维纳发表了控制论，他认为管理是一个控制过程。

1958年，盖尔写到：“管理将以较低的成本得到及时准确的信息，做到较好的控制”。

这个时期，计算机开始用于会计工作。

数据处理一词已经出现。

管理信息系统起初应用于最基础的工作，如打印报表、计算工资、人事管理等，进而发展到企业财务管理、库存管理等单项业务管理，这属于电子数据处理（EDP，Electronic Data Processing）系统。

简易的网吧计费系统设计
设计一个简易的网吧计费系统，要求上网人输入卡号和密码上机，卡号或密码不正确，不能上机，卡余额不足不能上机；正在使用的机器不能被再使用；上机需要记录卡号、机器号、上机时间；下机时需要记录下机时间、发生费用和自动从卡里扣款，该机器能再被使用；下机时，需要向用户显示本次上机的详细信息。
