1. 问题分析

1.1 问题描述

1.题目《人员信息管理系统》设计

2.设计说明与要求

（1）    公司主要有4类人员：经理、技术人员、销售员、销售经理，要求存储这些人的姓名、年龄、工资信息。

（2）    工资的计算方法

A、              经理：固定为8000元；

B、技术员：工作时间*每小时酬金（100RMB）；

C、销售员：4%提成；

D、              销售经理：1%提成+固定工资（5000RMB）；

（3）    实现功能

①  录入：输入各种数据，并录入TXT文件保存；

②    显示：显示员工的数据信息；

③    查找：查找员工的数据信息；

④    修改：修改员工的数据信息；

⑤    删除：删除员工的数据信息；

⑥    退出：退出本系统；

⑦    清理存储文件：清理系统产生的TXT文件；

2. 总体设计

2.1 功能分析

使用面向对象的程序设计思想进行分析，整个系统涉及两大类信息和操作，公司，人员。所以系统主要涉及两个大类：公司类business、人员类person。系统的总体框架就是公司类，人员类的定义；主函数中定义一个公司对象，循环显示主菜单并根据用户选择调用公司类的相应方法(成员函数)。

3. 详细设计

3.1 程序结构图

3.2 程序类结构图

3.3 程序类结构图

4. 功能测试

4.1 本系统的主界面

4.2 录入功能的主界面

4.3 显示功能的主界面

4.4 查找功能的主界面

4.5 修改功能的主界面

4.6 删除功能的主界面

4.7 清理功能的主界面

4.8 退出功能的主界面

5. 课设小结

根据课程设计的要求，我思考出了自己的课题，我用本学期所学的C++面向对象的知识来编写程序。我利用面向对象的方法以及C++的编程思想来完成系统的设计，在设计的过程中，建立清晰的层次，当然在调试过程中我也遇到了许多问题。

本程序由雇员这个基类派生出多个派生类，并且调用多个函数。主函数主要运用选择结构。派生类中的保护类数据要通过定义公有类型的函数来从类外调用。和一些相当复杂的算法，自己看了都乱，头都晕。不过，我相信，不经历风雨怎么能见彩虹。在解决了这一切后，我有一种：天将降大任于斯人也，必先劳其筋骨，饿其体肤的感觉！
