Analysis and Design of Library System

Abstract In this paper, a detailed analysis and design of library system development process is described。 The article is about analysis, design and implementation。 The design of the system is mainly discussing about topics background and significance of analysis; System analysis is mainly on the system requirements analysis, detailed planning for the flow of data, at the same time, also including the details of the data, the data dictionary。 System design is analyzed about from general to specific provisions of the local to the system , including the relationship between the module, the module, such as how to read data from the database and key code。

This paper can supply a feasible solution for the development of the library system design and the paper analyzes the current situation of domestic books management, finally achieved by using J2EE technology and MYSQL database library system development, through unit testing, system testing, reached the goal that the system is strong maneuverability , clear logic, and fully functional design。

This book management system’s main function is releasing announcement,book management,reader management and borrowing book。Managers are responsible for releasing announcement and managing books。As the same time,reader can borrow books and modify password。In generally,the system is strong and simply operating。
