摘要
随着移动计算的广泛应用,数据同步技术在分布式环境下发挥越来越大的作用。针对分布式移动环境的特殊性,研究并提出一种基于双时间戳的数据增量同步机制,为移动数据库复制技术提供一种可行的解决方案。在保证数据一致性的同时,为系统层级扩展提供了新的思路。实验结果表明,设定合理的批量传输单位能有效地提升同步机制的可靠性。最后设计并实现移动执法智能终端系统,辅助现场作业。
Along with the wide use of mobile computing,data synchronisation technique plays an increasing important role in distributed environment. To deal with the specificity of distributed mobile environment,we studied and proposed a double timestamp-based data increment synchronisation mechanism,which provided a viable solution to mobile database replication technology. It presented a new thought to the hierarchical expansion of system while ensuring data consistency. Moreover,it was demonstrated through experimental results that to properly set bulk transfer units could improve the reliability of synchronous mechanism effectively. Finally we designed and implemented the intelligent terminal system of law enforcement to help site operations.
