Research On The Consistency Of Shared Data In Mobile Social Content Management System

Mobile social software, as the main way of people’s social activities, is the main entrance and exit of data source and content displays. Cloud server for data organization and management, which sends the content organized to the mobile terminal presented to user, according to the request of the user. This whole constitutes the mobile social content management system. The content can be divided into two categories:one is private data; the other is shared data. There is no consistency for the maintenance of private data, because of involving a single user. But for shared data related to more than one user, it may cause inconsistencies when we operate these.According to the characteristics of data in mobile environment, this paper analyzes the process of shared data in detail and finds out the reasons that cause the shared data inconsistency of user. Studying deeply the consistency of shared data in the mobile social content management system, and exploring the solution to this problem of shared data inconsistency. The main research work and contributions in the paper are as follows:First of all, I find out the cause of shared data inconsistency through analyzing the process of shared data operations in the mobile computing environment. For this reason, this method is put forward based on the two phase message consistency control strategy in order to solve the problem of shared data inconsistency.Second, a consistency model is designed, which is two-phase message-consistency-control strategy and the mobile social content management system. This model, which controls the process that users modify the shared data, is implemented in the mobile social content management system.Third, I not only verify the correctness and performance of consistency model through experiments but also analyze the results of the experiments.
