在考生文件夹下完成如下简单应用：

(1)创建一个名称为sview的视图，该视图的SELECT语句用于查询salary_ db数据库中salarys表(雇员工资表)的部门号、雇员号、姓名、工资、补贴、奖励、失业保险、医疗统筹和实发工资，其中实发工资由工资、补贴和奖励3项相加，然后再减去失业保险和医疗统筹得到，结果按“部门号”降序排序，最后将定义视图的命令代码存放到命令文件t1.prp中并执行该程序。

(2)设计一个名称为form1的表单，表单以表格方式(与BROWSE窗口方式相似，表格名称为 grdsalarys)显示salary_db数据库中salarys表的记录，供用户浏览。在该表单的右下方有一个命令按钮，名称为Command1，标题为“退出浏览”，当单击该按钮时退出表单。

Women earn less than men do. For example, in 1998 the hourly wages of women in the U. S. were 26% less than those of men.

The gap between male and female incomes varies with age. The gap between the labor incomes of young women and young men

varies. It's also clear that jobs in which women are concentrated pay less. The larger the number of workers who are women in ran

industry, the lower the average wages.

Why do women earn less than men do? Can the differences be explained by the fact that women are looked

down upon? If so, the government has to intervene(干预), to force the employers to pay equal wages to equal jobs. However, there is no agreement among economists about the causes of

the gap. One view argues that women, on the average, have chosen low-paying jobs in which workers enjoy the freedom of entering and leaving the labor force, which reduces their years of experience relative

to men. Other people say the gap can also be explained by the difference in educational background.

Much of the gap, however, has not been fully explained. It might be the result of some prejudice (偏见) against women. It is this part that has produced calls for government action. What would happen if the government did intervene to

increase the wages paid to women? One possibility is that incomes for women as a group might actually decline (下降). An increase in wage decreases the quantity of labor imput demanded, resulting in decreased employment as the rate of hiring new

workers declines. The result will be a surplus 过剩) of labor. Those who can find jobs might be better off while those who had jobs

might find themselves out of work.
