/**该函数为内部数据维护，不提供输入数据服务。实体完整性，参照完整性，用户自定义完整性

出现错误则将错误输出到doc文档。

错误范围暂时定义如下：

1.同一房间的客户房间号不同(同房搜索！)

2.实缴费用大于应缴费用。(同房搜索！)

3.同一个客户在同一天两次住进宾馆(全表搜索！身份z号和入住日期相同)

4.同一身份z号，姓名和性别不同(全表搜索！)

另外，应该完成的任务有：

5.计算客户的应缴费用->对cost *** 作，需要用到：time,unit_price

6.计算客房的总住户人数（包括当前住户）->对totalclient *** 作，需要用到：没有

7.重新修订当前住户数->对currentclient进行 *** 作，需要用到：time

8.计算客房的总计收入->对income进行 *** 作，需要用到：fee

9.当前住户的实缴费用清零->对fee进行 *** 作，需要用到：time

完成这些 *** 作的先后顺序为：7->6->5->9->8->2->1->3->4*/
