（1）设计本次实验所需要的数据库的基本结构，并在数据库中录入部分数据，以便在编写程序时可以调用数据库中的相关内容，从而验证所写程序的正确性。

（2）设计登陆界面，设计label和text控件的相关属性，并且编写模块的相关代码，使得数据库与程序的连接能顺利的完成。

（3）进入主界面的编写,编写常用的工具列表，既美化了界面，同时方便了用户。在界面中更是包含了日历和时间，方便用户查询时间。

(4)其他窗体的编写。在房间调换的窗体中，如果没有相同类型的房间可供调换，text的内容会自动清空，焦点会自动停留在第一个文本框上。至于退房结账窗体的编写，大部分代码是为了实现对数据库的操作，综合利用了SOL语句的查询与数据更新（update方法），同时利用已经编写好的模块的调用，实现这一过程。-(1) The basic structure of the　design of experiments needed, and some of the data entered in the , so that when writing a program can call the relevant content　to verify the correctness of written procedures. (2) landing interface design, design label and text controls related properties, and the preparation of related code modules, makes the connection with the　program can be successfully completed. (3) prepare to enter the main interface, to prepare a list of commonly used tool, not only beautify the interface, while convenient for users. It is contained in the interface of the calendar and time, user-friendly query time. (4) Other forms prepared. In the room exchange form, if there is no room for the same type of exchange, the contents of the text is automatically cleared, the focus will automatically stop at the first text box. As for the check-outs form of written most of the code is to achieve operation of the , the comprehensive utilization of the SOL statement query and upda
