| Nowadays, in everybody’s daily life, mobile device has taken over a very important position. With the rapid development of mobile internet industry, the smart mobile platform will become a leading member of the next generation of communication area. Smart mobile device has been used to do business anywhere and anytime. Because of the disconnection characteristic of mobile device, in order to access the application for off-line mode, application data can be generally downloaded from the application database to the mobile device. And then it synchronizes with the remote database system from time to time when the connection is available. Therefore, the technique of data synchronization has become a hot research topic in recent years to make the mobile application realm developing more rapidly.The thesis is chosen from a module named data synchronization of a mobile application project. At the beginning, the current development and research status of the mobile computing has been given. Then a common used data synchronization protocol named SyncML, HTML5and netfilter architecture is introduced. And next, several existing mobile transaction processing and models of replicated mobile database have been analyzed. The implementation of the system is divided into two parts:Application Adapt module and Data Sync Control module. The analysis of the whole function, architecture design and implementation are focused. The final result indicates that the system can add the data synchronization function to the Web application, and data synchronization can be executed effectively. |
