摘　　要：传统的同步方法缺乏实时评估和分析机制,同步效果不佳。提出基于在线评测的主从式数据库信息快速同步方法。主数据库负责处理写操作并维护最新的数据,在改动时通知从数据库进行数据同步。引入在线测评工具,对同步的数据进行实时评估。以数据处理加速比作为评估指标,调整数据处理方式,设计数据库信息快速同步流程,通过反馈机制将同步结果返回给主数据库,确保同步的效果和质量。实验结果表明,该方法的CPU使用率在合理范围内,具备更佳的同步效果,累积误差分布概率较小,表明在信息同步过程中能够保持较高的可靠性。The traditional synchronization method lacks real-time evaluation and analysis mechanism,and the synchronization effect is not good.Therefore,this paper proposes a fast synchronization method of master-slave database information based on on-line evaluation.The master database is responsible for handling the write operation and maintaining the latest data,and notifying the slave database to synchronize the data when it changes.The online evaluation tool is introduced to evaluate the synchronized data in real time.Taking the data processing acceleration ratio as the evaluation index,the data processing mode is adjusted,and the rapid synchronization process of database information is designed.The synchronization results are returned to the main data-base through the feedback mechanism to ensure the synchronization effect and quality.The experimental results show that the CPU utilization rate of this method is within a reasonable range,and it has better synchronization effect,and the probability of cumula-tive error distribution is small,which indicates that it can maintain high reliability in the process of information synchronization.
