题目：《图书管理软件设计报告》

一、基本介绍

二、需求分析

2.1

该软件主要面向图书管理员和学生用户

2.2

管理员可进行图书的添加删除，也可以对书籍借出和库存情况进行统计，还可以添加新的管理员，学生用户可以查询图书的相关信息，然后进行借阅，但借阅时需要再次输入用户名和密码进行确认，归还时也需输入用户名和密码进行确认。

2.3

管理员在登陆时输入账号密码选择管理员登陆即可使用统计、添加、删除和添加管理员功能，学生选择用户登录，登陆后即可使用查询借阅归还功能。

三、概要设计

3.1软件功能：

3.2软件操作流程：

学生可借阅图书、归还图书以及查询图书信息，管理员可以添加图书、删除图书以及查询图书库存信息，还可以注册管理员。

3.3软件界面设计：

登陆界面

注册界面

还书界面

借书界面

查询界面

添加界面

删除界面

四、详细设计

4.1登陆界面

五、软件测试

软件测试无异常，可正常执行。

六、用户使用说明

管理员账号：admir 密码：123

用户账号：gu 密码：1111（还有部分管理员账号、用户账号，此处仅给出两个范例，其他账号可打开text文件自行注册）

管理员账号和用户账号可以自行注册，所有添加的图书、注册的账号等都会保存在text文件中，运用了文件处理的数据处理的方法，使用tkinter第三方库完成编程。Login-true文件中存储用户账号及密码，login-admir中存储管理员账号及密码，books文件中存储书籍信息，book-lend中存储借出的书籍信息。

login Page为登录界面，register Page为注册界面，user-main page为用户登陆后的主界面，admir main page为管理员登陆后主界面，view user为用户操作的界面，view admir 为管理员操作的界面，打开main.py文件即可运行程序。

七、大作业总结与体会
