| With the increasing expansion of the mobile phone reading business,the content manage unit, abbreviated as CMU, needs to be reconstructed to meet the business expansion. However, the business of CMU is complex. There are many operations of data synchronization, and the requirement of synchronization is not uniform. It is urgent to build an intelligent and scientific data synchronization system.In this thesis, a design and implementation of mobile reading management platform data synchronization program is proposed based on the reconstruction of mobile reading management platform. It mainly solves the data synchronization problem in coexistence period of new and old systems and synchronization problem of general database and content database during the new CMU independent operation. Data consistency verification, system configuration issues are also considered. On the basis of previous research, the principle of synchronization, synchronization of the old and new systems without invasion, a variety of synchronization trigger modes, synchronization task priority, the flow control and synchronization verification are innovatively studied in this thesis. In this thesis, the function, reliability and performance of the system are tested.The data synchronization system based on this thesis has provided service normally for a long time in current network of China Mobile mobile reading base.The main work of this thesis includes:1. Research the principle of data synchronization for CMU system,and analyze the usage scenarios of each principle and the technical scheme of implementing each principle. Finally, the synchronization system is designed and developed based on the principle of synchronization.2. Determine the synchronization scheme of the new and old system.Completion of the JDBC transformation to realize the data synchronization of the old and new systems without invasion innovatively.3. Propose synchronization task concept. Design and implement the content synchronization module with synchronization task as the basic unit. Combined with CMU business, design and implement task priority queue and SQL priority queue. Implement the asynchronous SQL actuator with flow control to improve the efficiency of task execution.4. In order to ensure the accuracy of the synchronous task, propose content verification scheme. Design and implement the content verification module with verification task as the basic unit.5. A configuration management scheme for timing triggered synchronization tasks and verification tasks is provided. And in order to facilitate effective management of synchronization task and verification task, design and implement management interface. |
