Recently, the school’s database theory course has ended, and a big homework needs to be done, and a graphical interface is also required. Now I share my source code. There are many deficiencies, and I am too lazy to change it. I will give you a reference.
The specific functions to be realized are books, adding, deleting, checking and modifying reader information, changing real-time inventory by triggering borrowing and returning books, paying overtime fines, etc. The following are my sql code and python code
Book information (book_information): book number (book_id), book name (book_name), author (author), category (book_category), publisher (publisher), total number of books (book_total) reader information table (reader_information): reader number (
reader_id ), name (reader_name), class (reader_class), reader category (reader_category), number of books that readers of this category can borrow (reader_borrowednumber),
book inventory table (book_inventory): book number (book_id), remaining inventory number (book_surplus)
readers Payment table (reader_payment): reader ID (reader_id), fine to be paid (reader_fine)
reader borrowing table (reader_borrow): reader ID (borrow_id), borrowed book name (borrow_bookname) borrowing time (borrow_date)
reader return table ( reader_back): reader number (back_id), book name (back_bookname), book return time (back_date)
CREATE TABLE book_information (
book_id INT PRIMARY KEY,
book_name NVARCHAR(50) 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
