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 of management system in line with its own actual situation to seek truth from facts.实验项目名称： System design 实验学时： 4 同组学生姓名： 实验地点： 实验日期： 实验成绩： 批改教师： 批改时间： 一、实验目的和要求Use case modeling, Class modeling, and dynamic modeling.二、实验仪器和设备硬件：PC 软件：Office 2010 Astah三、实验过程Library Management System（LMS）-Software Design1.Introduction1.1 In front of the management systemIn recent years, with the rapid development of Chinese book market, the librarys collection is rich, and there are many libraries still using artificial way to carry on the management of books, heavy workload, long working time, a serious waste of manpower, material and financial resources, not conducive to the circulation and management, the books so, the development of the library management system to become a problem that needs urgent solutions.The library is to provide service for our study and work. 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.
