一 系统的背景
从事商业活动的公司迫切需要这样一个系统：它能高效的管理公司内部所有员工的个人信息，并能正确快速的对系统的使用者的操作做出回应，以提高效率，降低成本。
该系统能够满足以上的要求，使用户可以快速准确的管理公司员工的信息。
二 系统的编译环境和语言
该系统是采用C++语言在Turbo c下编译而成,。
因为在该系统中有明显的对象，即是公司的员工，且C++语言是一个非常强大的面向对象的语言，因此该系统使用C++编写将会简单，快速而有效。
Turbo C是一个经典且功能强大的编译器，是编译用C++语言写成的程序的首要工具。
三 系统类的设计
3.1 类的对象：
系统有两个类:
Employee ：对象是公司里的每一个员工，是系统中最重要的类。
DBOperate ：对象是系统的数据文件，完成对员工信息的保存和读取。
3.2 类的属性列表：
Employee ：
员工的编号：EmployeeNum (long)
员工的姓名：EmployName (string)
员工所属部门：EmployeeDepart (string)
员工级别：EmployeeGrade (string)
员工工资：EmployeePay (float)
员工工龄：EmpoyeeWorkTime (long)
3.3 类的行为：
Employee ：
添加新员工信息：NewInfo();
员工信息浏览：ShowInfo();
员工信息变更：RefreshInfo();
发放工资：    Pay(int EG);//EG为员工级别
解聘员工：  DeleteInfo();
DBOperate ：
保存员工信息：WriteIn(int iflag);
读取员工信息：ReadOut();
更新员工总人数：RefreshMaxNum(int iflag);
注释：当iflag 为1时，人数增大；为零时，人数不变，即是修改；为 -1时，人数减少。
3.4 具体代码如下：
long Employee::EmployeeMaxNum = 1000;
float Employee::EmployeeBasePay = 1500;

 int Employee::MaxNum()
 {
  int MN = 0;

  ofstream myof("c://EmployeeMaxNum.txt");
  myof<<MaxNum;
  myof.close();
 }
 

四 系统运行入口的设计
提供一个操作界面入图：

 
 
注意：系统中有全局变量用于存储从数据文件中读出的员工信息
char *EN[50];
long   ENum[50];
char *ED[50];
int EG[50];
long   EWT[50];
float  EP[50];
该系统的操作就是围绕这些全局变量展开。

代码如下：
void main()
{
 int c2 = 0;
 while(c2!=5)
 { 
  cout<<"Employee Information Manage System"<<endl;
  cout<<"******************************************"<<endl;
  cout<<"* Employee                List-----------1"<<endl;
  cout<<"* Add New Employee Information-----------2"<<endl;
  cout<<"* Refresh Employee Information-----------3"<<endl;
  cout<<"* Delete  Employee Information-----------4"<<endl;
  cout<<"******************************************"<<endl;
  cout<<"* Exit EIMS------------5"<<endl;
  cout<<"******************************************"<<endl;
  cout<<"Input your choice on here > ";
  cin>>c2;

  Employee e;
  DBOperate dbo;
  switch(c2)
   {
    case 1:
     dbo.ReadOut(); e.ShowInfo(); break;
    case 2:
     e.NewInfo(); break;
    case 3:
     e.RefreshInfo(); break;
    case 4:
     e.DeleteInfo(); break;
    case 5:
     break;
    default:
     cout<<"Error! Your Choice doesn't Exit"<<endl;
   }

  if(c2 == 5)
   break;
 }
}
 

五 运行步骤
运行主界面：

【步骤1】：选择1，系统将已有的员工信息依次显示在屏幕上。

【步骤2】：选择2，系统将添加新的员工信息。
【步骤3】：选择3，系统将更新指定的员工信息。
 
【步骤4】：选择4，系统将删除指定的员工信息。

【步骤5】：选择5，退出系统。
 

六 数据文件
Employee.txt 存储员工的基本信息
EmployeeMaxNum.txt 存储员工的人数
数据文件都存放在C盘根目录下。
该系统对数据文件的操作在系统运行过程中非常重要，是使整个系统正常运行的关键。
