Mobile Library Service System Design And Implementation Of The Application Side

Mobile application developed rapidly because of the Combination of MobileCommunication and Internet. The service of mobile application offers the informationfrom internet for us. The paper applies the mobile application technique to search bookin the library and designs the Mobile Library System. It can bring convenience foruniversity students to searching and borrowing book.Above all, the paper analyzes the advantages and disadvantages of existing in themobile application. Then, the Mobile Library System based on Java2ME and Java2EEis proposed in the paper. With consideration of maintaining, reusing and extending ofthe system, Java2EE3-Tier architecture is adopted in the system. According to thecharacteristic of the Mobile Library System, on the designing of mobile clientapplication, interface and data model achieve separation because that MVC designingmodel are adopted, using scale method achieve picture zoom function in the Canvasclass, using Push registration mechanism achieve regularly reminded of the bookfeatures, developing a generic Table UI components to show results.In this platform, library service of mobile application terminal system based onAndroid system has the following innovative points:(1) compared to the current modeof library service system design and implementation, the mobile application system onthe platform for Android, the client program more diversified forms and rich in content.(2) using the three layer architecture structure of the whole system, three layersarchitecture can fully guarantee the system reusability, maintainability and scalability,the system realized in this way can fast and convenient for application deployment.
