Research And Implement Of Mobile Services System Of Cluster Library Based On J2EE Architecture

With the rapid development of our country’s libraries, regional cluster libraries, this new innovative system also was born in order to achieve resource sharing and collaboration and mutual assistance.At the same time, the application of mobile services in the library industry are increasingly popular.In order to meet a number of libraries’s demand for mobile services, this paper studies how to build the mobile service system in the environment of clustered libraries.The system can be logically divided into SMS platform,WAP platform, the reader’s Web platform and the background management platform of four major sections.Firstly,the paper uses the Unified Modeling Language UML for system analysis and design,and the system is described from a static and dynamic view of two different view angles.Then,using the widely used J2EE platform and the MVC design pattern construct system,and this allows the system to have good stability and maintainability.At the same time,system uses the open-source Struts framework of today’s mainstream to reduce the coupling between the system’s layers and also reduce the development complexity.Finally,system achieve some important functional blocks,including the service of mobile binding,the due reminder of borrowed books,the query and statistics of SMS’s logs,the release announcement,etc.This first chapter of this paper introduces the concept of mobile service system in cluster library,the significance of the research,as well as the domestic and foreign research.The second chapter describes the relevant technologies which the system has used,for example, J2EE platform architecture, the Unified Modeling Language UML, MVC design patterns and Web Service technology.The third chapter is about the systems analysis and design,First,requirements analysis of the system is done, and describe the system’s requirements through the use case model,and a detailed analysis and modeling of some important use cases of the system has been done;Then, the overall design of the system is done,mainly introduces the system architecture, functional architecture, the deployment architecture and interface design,at the same time, the system logically has been divided into multiple subsystems,and various subsystems are in detail designed respectively.and the sequence diagram and state diagram of some modules are drawn; finally, a brief description of the database’s conceptual design and logical design is done.The fourth chapter describes the system’s implementation, first, a brief introduction of the system’s deployment configuration is achieved,then has introduced the implementation of the various subsystems,and gives the program flow chart, the detailed implementation’s class diagram as well as some critical code of some important module.The five chapter briefly summarizes the main tasks of this paper, as well as the problems which is existed in the paper,and further research work has been prospected.
