The system brings convenience for librarians and readers to borrow and return books through powerful computer technology. In addition to the general functions of library management, the system also includes the functions of online book information inquiry, personal borrowing and renewal. The objectives also include:

Reduce manpower and management costs;

Improve the accuracy of information;

Improve management and services;

Establish an efficient information transmission and service platform to improve the speed and utilization of information processing;

Excellent system design, exquisite, friendly, fast and humanized interface design, powerful and efficient background management function;

Simpler and richer book management process;

2 characteristics of users

The end users of this software are administrators (librarians and other managers) and readers (teachers and classmates, etc.). ). They all have a certain computer application foundation and can operate computers skillfully. Administrators and readers are ordinary users.

System maintainers are computer professionals who are familiar with database, operating system and network maintenance. Maintenance personnel are interval users.

3. Demand adjustment

In the book management system, the administrator should establish a borrowing account for each reader and issue different types of borrowing cards to readers (borrowing cards can provide card numbers and readers' names), and the personal information and borrowing record information of readers are stored in the account. Readers with a library card can borrow and return books through the administrator (as a reader's agent to interact with the system). Different types of readers can borrow books in different scope, quantity and time limit, can inquire about book information and personal borrowing through the internet or the inquiry terminal in the library, and can also renew books (the system audit meets the conditions for renewal).

When borrowing books, first enter the reader's borrowing card number, and the system will verify the validity of the borrowing card and whether the reader can continue to borrow books. If it is invalid, the reason will be prompted. If it is valid, the basic information of the reader (including photos) will be displayed for the administrator to view manually. Then enter the book number to be borrowed, and the system consults the book information database to display the basic information of the book for the administrator to manually query. Finally, submit the borrowing request. If it is accepted by the system, save the borrowing record and modify the number of books that can be borrowed. When returning a book, enter the reader's borrowing card number and book number (or lost tag number), and the system will verify whether there is such a borrowing record and whether it has expired. If not, you will be prompted. If there is, the basic information of readers and books will be displayed for the administrator to review manually. If there are overdue loans or losses, they will be transferred to overdue fines or book losses first. Then submit the book return request, delete the borrowing record after the system accepts it, and register and modify the number of books that can be borrowed.

Librarians regularly or irregularly manage book information such as warehousing, modification and deletion, and cancellation (not borrowing), including book category and publishing house management.

Provide general functions such as authority management and data backup for system maintenance personnel.
