Research On Mobile Database Synchronization Technology Based On Mobilink

These years, along with the emergence of smart mobile devices, mobile database technology development and application, but there has also been a lot of problems, such as mobile data replication process is how consistent that it does not conflict resolve these issues can well provide convenience to people’s lives.In order to study the efficiency of mobile database replication, Firstly, the paper starts from the replication of the third level---client cache in the three-tiers replication strategy, studies and analysis the client caching mechanism and offers two confliction reduction methods---Relate Transaction Scheme and Time Limit Scheme. Based on that the paper also improves the client upload algorithm and download algorithm. Then, the paper introduces the MobiLink synchronization technology and set up the synchronization achieve model. Last, propose a mobile database synchronous replication model based on MobiLink with the three-tiers replication system. Besides, the paper gives a detailed devise and research on that model and makes a simple performance analysis.
