学校图书借阅管理系统（python + sql serve）数据库大作业
最近学校数据库原理结课，需要做一个大作业，还要求写图形化界面，现在分享我的源码，有很多不足之处我也懒的改了，给大家参考一下
具体要实现的功能为图书，读者信息的增删查改，借书还书触发器更改实时库存，超时罚款缴纳等下面是我的sql代码和python代码
图书信息（book_information）：图书编号(book_id)，图书名(book_name)，作者(author)，类别(book_category)，出版社(publisher)，图书总数 （ book_total）
读者信息表(reader_information)：读者编号(reader_id)，姓名(reader_name)，所在班级(reader_class)，读者类别(reader_category)，该类别读者可借阅册数(reader_borrowednumber)，
图书库存表(book_inventory)：图书编号(book_id)，剩余库存数(book_surplus)
读者缴费表(reader_payment)：读者编号(reader_id)，待缴罚款(reader_fine)
读者借书表(reader_borrow)：读者编号(borrow_id)，所借书籍名称(borrow_bookname)借书时间（borrow_date）
读者还书表（reader_back）：读者编号（back_id），所还书籍名称(back_bookname)，还书时间（back_date）
CREATE TABLE book_information (
book_id INT PRIMARY KEY,
book_name NVARCHAR(50) NOT NULL,
author NVARCHAR(100) NOT NULL,

create table reader_back(
back_id NVARCHAR(50), --为了比较成功运行触发器，borrow_id为借书人的名字
back_bookname NVARCHAR(50) NOT NULL,

)--读者还书表
create view book_select(书号,书名,总数,在馆册数)--图书信息查看视图

--借书还书存储过程返回借书日期和还书日期，返回值用列表的两个值相减得出超时天数计算罚款值，交罚款的时候先插入还书记录。获取还书时间，还书表和借书表连接创建视图，如果还书时间减借书日期大于7，选中这个人，

end
--连接借书还书表创建视图
