【题目】便利店管理系统
【目的】
通过设计一个小型的便利店管理系统,训练综合运用所学知识处理实际问题的能力,强化面向对象的程序设计理念,使自己的程序设计与调试水平有一个明显的提高。
【要求】
1、每个学生必须独立完成;
2、课程设计时间为1周;
3、设计语言采用C++;
4、学生有事离校必须请假。课程设计期间,无故缺席按旷课处理;缺席时间达四分之一以上者,未按规定上交实验报告的学生,其成绩按不及格处理。
【内容简介】
有一家小芳便利店,现在需要你为这个便利店开发一个简单的便利店管理系统,方便顾客自己购买商品,并提供对便利店销售情况的统计和管理功能。
【考核标准】
该系统为两种角色的用户提供服务,一种是便利店管理员,一种是顾客。便利店管理员根据账号、密码登录系统,顾客无需登录即可使用系统。
1、 顾客通过该系统购买商品,可实现多次购买一次性结账, 商品信息包括商品编号、商品名称、商品价格,商品包括普通商品和进口商品,进口同类商品价格是普通商品的1.2倍, 系统能够根据顾客的要求正确打印订单,订单内容包括订单编号、商品名称、商品的价格、商品数量、折扣等,显示进口商品名称时,在名称后加;管理员可以查看当天以及当月的所有订单,成绩≥60;
2、 系统退出后能保存当天的销售信息,要求每天一个文档,文档名按照日期命名。管理员可以根据订单编号查找删除修改某个订单,订单可以按照下单时间先后排序,成绩≥70;
3、 能够实现管理员对商品名称和价格的管理,包括对商品和对应价格的增加、修改、删除、查找,成绩≥80;
4、 系统可根据历史记录对销售情况进行统计,根据管理员的输入日期统计某天的销售情况并显示(包括一共销售多少单,销售额是多少,各种商品的销售情况),成绩≥90.
5、 有能力的话,可以考虑会员和非会员的情况.
要求:
用面向对象的程序设计方法设计该系统。本系统涉及的基本对象有订单对象、订单管理对象、商品对象、进口商品对象、购物篮对象、商店对象。实现对这些对象的合理抽象和封装,正确定义类之间的关系。界面合理,代码文件组织清晰,命名符合规范,代码注释清楚,课设报告书质量高。
【工作内容及工作计划】
一、 题目
便利店管理系统
二、 需求分析
1、 用户分析
管理员:
- 商品名称和价格的管理,包括对商品和对应价格的增加、修改、删除、查找;
- 输入日期统计某天的销售情况并显示;
- 管理员可以根据订单编号查找删除修改某个订单,订单可以按照下单时间先后排序;
- 查看当天以及当月的所有订单。
顾客: - 非会员和会员不同权限;
- 查看、选择、购买商品;
- 修改、删除、查找顾客购物车订单;
- 结账付款。
2、 文件系统分析 - 每天一个文档,文档名按照日期命名;
- 管理员账号、密码;
- 会员信息;
- 单个订单信息。
3、 对象分析 - 商店对象、列表对象、订单对象、订单管理对象、商品对象、购物篮对象、用户对象、管理员用户对象、顾客用户对象、时间日期对象、菜单对象、商品目录对象。
- 对象的合理抽象和封装,正确定义类之间的关系;
三、 系统结构图
四、 类的设计
五、 程序代码与说明

六、 运行结果与分析
七、 心得与体会
- 掌握类的概念、类的定义格式、类与结构的关系、类的成员属性和类的封装性;
