In this paper, a new method of mobile data synchronization is proposed to achieve the consistency of data, the storage of the difference in log, and the optimistic copy method of C/s structure. This method effectively reduces the communication overhead and effectively solves the problem of synchronization and consistency of terminal data in mobile environment. The system design takes into account the usability, efficiency, comprehensiveness, extensibility and accessibility, ensuring the robustness of the system and the efficient use of data. The system can be divided into platform side and mobile terminal side, the platform side receives each client's synchronization request, carries on the synchronization processing, interacts with each client, maintains the data synchronization with each client; The mobile terminal maintains a local mirror database consistent with the cloud data locally, and when the user updates the data synchronously, The local data is compared with the mirrored data, synchronized to the mirror database, and then synchronized by the mirror database to the Cloud Master synchronization module. When the client receives a synchronization request from the cloud, it also updates the mirrored database, and then updates the data in the mirrored database to the local record data. Mobile terminals via HTTP POST (?) Interaction with the platform side main synchronization module, the interactive content exists in XML form and placed in the message body of the HTTP post. Finally, a series of tests are carried out to ensure the complete function, excellent performance and good user experience.
