Research And Implementation Of Heterogeneous Data Synchronization System For Cloud Environment

With the rapid development of technology and mobile Internet in recent years,various intelligent terminals have been widely applied to people's daily life and work.However,due to the unbalanced development of mobile networks in different regions,terminal software,completely depending on network,cannot be used normally when there is no network or the network environment is poor,while offline software cannot support data sharing among multiple devices in cloud environment.The launch of data synchronization technology has solved these problems so that people can easily share address list,calendar and other information to multiple devices without worrying about loss of important information.However,the complexity of data structure is growing with more complex functions of application software,and the increasingly fierce competition has accelerated the frequency of software updates,so data structure will also change with software updates,and traditional data synchronization technology will be difficult to be applied to this environment.On the basis on research and analysis on existing synchronization technology,this paper has proposed a complete heterogeneous data synchronization scheme,developed the synchronization mechanism and planned specific synchronization types.A specific solution is studied and designed in view of the core issues in data synchronization,such as data change determination,data conflict processing and big data synchronization processing.In addition,the specific methods supporting data structure upgrading and heterogeneous data synchronization are studied and designed in combination with the features of constant upgrading and improvement of software in nowadays to release the synchronization system from the synchronization of specific data,and achieve independence from functional services so as to be well applied to more complex business scenarios.At the meantime,a heterogeneous data synchronization system is designed and developed by combining the proposed heterogeneous data synchronization mechanism,which can well deal with the problem of data synchronization of multiple terminals in cloud environment to support the structural upgrade and change of business data,and has been successfully applied in production to achieve the anticipated goal.
