ystem. The digital library management system is mainly used for the management of books, readers, and borrowing. It not only simplifies people's work, but also systematically manages books and readers, and timely statistics on all borrowing records. It also has functions such as announcing news, allowing readers to understand the latest developments in the library. Its application is very wide, it can be used in the libraries of various universities, the book collections of corporate groups, and in large bookstores providing lending services etc. The system is developed based on the B/S structure, using JSP programming language and MYSQL database for development; the main work completed includes overall system design and planning, library database design, system page production and beautification, customization of system security levels and system programming, debugging and modification. This paper first analyzes the requirements of the library management system; then it designs and implements the database and various functional modules of the digital library management system in detail, including book search, book borrowing, announcements, messages, and backend management modules; finally, through testing and analysis, it is demonstrated that the system runs stably, reliably, and has certain practical value. Keywords: library; JSP; MYSQL Background and significance The traditional library management methods are unable to keep up with the modernization of library management. With the rapid development of information technology, it has become an urgent need to establish a digital library management system to replace the traditional one. The digital library management system can help to simplify the management of library resources, improve the efficiency of library services, and provide more convenient and advanced services for readers. Therefore, the design and implementation of a digital library management system have very important practical significance and broad application prospects. Structure arrangement of the thesis This thesis is divided into several chapters, including the introduction, development technology introduction, requirements analysis, feasibility analysis, functional analysis, business process analysis, database design, ER diagram, data dictionary, data flow diagram, detailed design, system screenshots, testing, conclusion, acknowledgments, and references. Introduction to development technologies The library management system in this thesis is developed using JSP, servlet and SQL Server. The JSP programming language is used for front-end development, while servlet is used for back-end development. SQL Server is used as the database management system. These technologies are widely used in the development of web-based systems and have the advantages of good scalability and high security. Requirements analysis The requirements analysis of the library management system includes the analysis of functional requirements and non-functional requirements. The functional requirements mainly include user management, book management, borrowing management, announcement management, message management, and backend management. The non-functional requirements mainly include performance, security, and usability requirements. Feasibility analysis The feasibility analysis of the library management system mainly includes technical feasibility, operational feasibility, and economic feasibility. The technical feasibility analysis mainly considers whether the system can be developed and implemented using existing technologies. The operational feasibility analysis mainly considers whether the system can be used effectively by users. The economic feasibility analysis mainly considers whether the development and operation of the system are cost-effective. Functional analysis The functional analysis of the library management system mainly decomposes the system functions into modules, and then analyzes and designs the specific functions of each module. The main modules of the system include user management, book management, borrowing management, announcement management, message management, and backend management. Business process analysis The business process analysis of the library management system mainly analyzes the business processes of book borrowing, book return, announcement publishing, and message exchange. By analyzing and optimizing these business processes, the system can provide more efficient and convenient services to users. Database design The database design of the library management system involves the design of database tables, indexes, and constraints. The ER diagram and data dictionary are used to present the database design in a clear and understandable manner. The data flow diagram is used to describe the flow of data in the system. Detailed design The detailed design of the library management system mainly includes the detailed design of each module, including the design of user interfaces, data processing logic, and data storage structures. The system screenshots are used to illustrate the user interfaces of the system. Testing The testing of the library management system mainly includes unit testing, integration testing, and system testing. The purpose of testing is to ensure that the system runs stably, reliably, and effectively. Conclusion In conclusion, the development of the library management system in this thesis is successful and has practical value. The system runs stably and reliably, and provides efficient and convenient services for users.
