Design And Development Of Information Management System Of The Library Based On C/S Architecture

This paper discusses the present situation of the library information and the existing problems, and puts forward some solutions and suggestions. Detail design and development process of library information management system.Feasibility analysis and requirement demonstration, carries on the demand analysis from four aspects: the system administrator scene, library management, the reader management scene scene and lending management scenarios, use case diagram indicates the relationships between them and the system boundary. Application of activity diagram describes the system pre borrow books, borrow books, renew a book, but also the dynamic behavior of book of business process, the data flow diagram analysis of the flow and processing motion data in the system, obtained the data storage entity, processing method and other design elements. Finally, with the UML deployment diagram, describes the system operation in the actual hardware environment.Design and implementation of system, using class diagram for domain modeling, the use of UML sequence diagrams to business scene as the foundation, analyzes the dynamic interactive relationship between classes of the scene. The establishment of a conceptual data model by the E-R way(CDM), and derived the physical data model(PDM), using the text describes the calling sequence and behavior between the different levels of.The system of C/S three layer architecture and design mode based on.NET technology, realizes the main functions of the system development foundation information maintenance, library books management, reader information management, library information management, reports and statistics module.Finally has carried on the system function testing, performance testing, usability testing. The test results show that the system is safe and reliable, and can fully satisfy the requirements of users.The development and application of this system in improving the information level of library management, standardization of library business process, has the extremely vital significance to improve the quality of service and the service of library processing power, has a good reference for the information construction of library.
