The library management system is designed and implemented using the most popular SSM framework in JSP, Eclipse editor, and MySQL database. The website functions include system user management, book management, user management, borrowing management, renewal management, illegal payment management and other modules. The design framework of the entire system is outlined, the construction of the system software development and compilation environment is introduced, and the function of each module and the design process of the program call relationship are explained. The library management is established to facilitate the user's inquiry of the book information he needs through the administrator's entry and release of book information. Once the book information he needs is inquired, the user can obtain the book information information from the system , In order to facilitate online and timely release. If the user does not find the book information information he needs, he can also remind the administrator to add it online. In this way, the system aims to establish a bridge relationship between users and managers, so that users can obtain information from managers in a timely and effective manner. Therefore, we think it is very necessary to establish an online library management, and its convenient, efficient, simple and fast management mode is very useful.
The system mainly includes multiple functional modules such as book management, user management, and renewal. The following is a brief description of these functional module requirements. Different permissions correspond to the requirements of the corresponding functional modules. The administrator has the highest level of permissions, so the corresponding requirements are the most. The following briefly explains the requirements of each permission according to different permissions.
The corresponding functional requirements of the
administrator are as follows: the administrator has the highest authority and can manage the system's books, user information, renewal and other information in a unified manner.
Administrators can add administrators, add more administrators, and can modify and delete administrator information.
Regarding books, administrators can add books, add related books’ publishers, borrowing times, inventory, categories, pictures, book numbers, book descriptions, book names, authors, and other information. The added books will be displayed in the system, and they can also be passed Keyword search query, administrators can also modify and delete related books.
Regarding renewal management, the administrator can add renewal, add information about the renewal publisher, borrowing list number, borrower, borrowing date, inventory, category, book number, book name, renewal days, author, etc. , The added renewals will be displayed in the system, and search queries can be made by keywords, and the administrator can also modify and delete related renewals.
Regarding the management of illegal payment, the administrator adds the illegal payment, the amount of the fine, the type of the fine, the details of the fine, the number of the borrower, the borrowing date, the category, the serial number, whether to pay the payment, Books and other information, added illegal payment will be displayed in the system, you can also search and query by keywords, and the administrator can also modify and delete related users.
Regarding the borrowing management module, the administrator can add borrowed books, such as the publisher, borrower number, borrower, borrowing date, inventory, category, book number, book name, author, etc. The added borrowed books will be displayed in the system, and you can search and query by keywords, and the administrator can also modify and delete related borrowed books.
The user's corresponding functional requirements are as follows:
Users can register through the system, and users who have completed the registration and passed the system audit can query and modify their basic information, such as modifying the login password.
Users can browse online through the website, check users of the website, borrow books, books, and renew online on the website.
