Research on Embedded Mobile Database Synchronization Model Based On Cache and Timestamp

摘要：

　　Traditional way for data synchronization is to create data transforming model through two-tier or three-tier replication based on features of the mobile client data model.This paper researches cache mechanism and analyze data synchronization via timestamps to establish synchronization model consists of primary server database,embedded mobile database,synchronization server and cache management.Blockade and database priority algorithm are combined in synchronization model and synchronization algorithm based caching and timestamps is illustrated.Experiments compare timestamp synchronization model with traditional ones from four aspects: communication throughput,transaction volume conflict,the algorithm running time and amount of mistaken update.Results indicate that data synchronization model used in this paper is more efficient and convenient.
