Introduction1.1 The preparation of purposeThe preparation of this requirement is to develop ways of LMS software research using large database foundation and application method. At the same time, it is also the foundation of project planning, preliminary design and detailed design, is the maintenance personnel perform internal maintenance, update, acceptance and test basis.Provided the development basis for software developers, since the directivity function in the process of software development.The main readers for software designers, programmers, and teacher.1.2Scope of projectThe project name is Library Management System. The main functions of the system include: the ability to store a certain amount of book information, and convenient and effective for books data management and operation, corresponding to a certain number of readers information storage and management of the corresponding; to provide a security mechanism, to provide data access. 1.3 DefinitionsData dictionary: It is a collection of data information, which is defined for all elements in the data flow graph contains a collection of. Its role is to provide data on the description information for designers.The data dictionary should be composed of the following definition four elements: data flow, data flow components (i.e., data elements, data storage, processing).1.4 ReferencesIEEE Standard 830-1998 IEEE Recommended Practice for Software Requirements Specifications. IEEE Computer Society, 1998.Software Engineering (Second Edition) Deng Liang song, Liu Haiyan2. Overall Description2.1 RequirementThis system should have the books information, readers information storage and management, and can save the book information, readers information, loan information, account information, and has the function of user management. The system can greatly reduce the librarians daily work, and provides library report, provide auxiliary decision function for library management librarian.2.1.1 FunctionThe function requirement analysis:(1) ManagerThe personnel information management:The reader information management, including readers category, gender, number, time limit for library books input, modify, delete, display.Library information management, including the administrator rights, gender, note, input, modify, delete, display.Library information management:Books basic information management, including the book number, categories, keywords, note and so on input, modify, delete, display.Library management system:Library information management, including the book number, number, date, readers borrow books borrowing limit, note and so on input, modify, delete, display.Return the books information management:Including books, readers, the book number number date, book period, note the input, modify, delete, display.(2) ReaderLibrary operation:Including books, book information, book operations, renewals, reservation. Lift the reservation operation.Personal information:Personal information query, modify password.Process flow Simplify:Reader ManagementRMLibrary ManagemenLMBorrow ManagementBMPersonnel InformationPILibrary InformationLIBorrow InformationBI LMSManagerReaderLIRMLLMBMPIBISystem model:2.1.2 PerformanceThe librarian management, performance requirements are not very strict, but the need to facilitate the storage of books and other operations. For readers, borrow, return the general order, for high performance requirements, the general need to achieve concurrent number more than 200.四、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
