The library store a large number of books, the books information and effective classification and management will greatly improve the operation efficiency, reduce the labor intensity of library staff, and the operation process of the library to do detailed, transparent, to provide protection for the work everything in good order and well arranged.1.2 The design goalThis design aims to analyze the feasibility of library management system development research, and provide a feasible plan for software development and summarized below.1.3 Software informationSoftware name: Library Management SystemDevelopment platform: Turbo C 2.0User: the library staff2.Overall DescriptionThis is a system for various independent library management software, the main function is to simplify the past manual management costs, the use of modern technology to achieve large-scale book from the book by the end of book circulation life cycle of the full range of convenient management.2.1Main functionThrough the computer to complete library in the library books management, complete with computer efficient, safe for Library and information processing, the liberation of the workers from the heavy data processing.The main function of the system of book information management, books information query, user management and so on, are divided into blocks, focus, relevance, optimization of the can, in accordance with the structured program design requirement, design of function module as shown in fig.The login module:.Library management module:The reader management module:The borrowing books module:Remarks:(1).The user does not exist.The book does not exist.Users report.User arrears.The existing capacity of 0.Renew module:The returning book module:2.2Performance requirementsa. Book information input, will book name, inventory number input system, establish the system database.b. Book information query, enter a title, display information about this book, including inventory, the number of loans, the remaining number.c. Book lending and return, input lent or return the books title and number, corresponding modification of inventory information.d. Book information insertion and deletion, the book to the library or to clear inventory, add or delete the corresponding information in the database.e. The books information, the existing database file, to prepare for possible period of want or need.f. Book information input, input the file name, file the information read from the database.g. Permissions problems, into the system before the input password, the password is not correct, exit the system.2.3The design strategyIn order to ensure the system scalability, in the design process adopted the following strategies:1, ensure the high cohesion and low coupling between modules and each functional module.2, the incremental model, good system scalability3, the design of appropriate space, support future extensionsIn order to guarantee the good reusability, in the design process adopted the following strategies:1, the interface oriented programming, support code reuse good2, component oriented programming system, further improve the reusability of code3, the design process using a variety of design patterns, to ensure the system reasonable and concise四、实验结果与分析The present era is the era of information, as the information collection, storage, processing, transmission center library should adapt to the changes of the times, must adopt new management system to realize the automatic and scientific management. Management information system with the management idea and design system from the introduction of the first, the work of library management to the library to meet the new era with a new look. Although the books management system management system in China in recent years has made great development. However, the foundation is weak, the imbalance of development; the overall level of the modern information technology of library is not high. Therefore, the development of Chinas Library under the network environment, according to the development situation of Chinas actual level of socio-economic development and information technology, the implement of management system in line with its own actual situation to seek truth from facts.This design makes me realize the library management in a scientific, efficient, and contains a lot of information and data management. In the face of such a huge amount of information, the library management system can improve the efficiency of management books. Through such a system, we can standardize information management, scientific statistics and fast query, thereby reducing the workload management.Through this design, I developed a comprehensive ability to use the knowledge of computer, especially has made great progress in the program design of database, programming technology, has a deep understanding of the development process, software system. In the future I will continue to learn, in later practice to summarize and accumulate, makes the library management system more perfect.
