摘　　要：为了防止信息“碎片化问题”的出现,实现对数据文件的稳定跨区域传输,提出面向分布式数据的跨系统数据同步中台构建方法。针对分布式数据库,确定数据分片原则对输入信息分离处理的具体影响效果,完成面向分布式数据的跨系统传输环境搭建。在此基础上,建立同步服务架构,按照已知的传输用例关系,确定关键性的中台运作机制,实现跨系统数据同步中台的应用需求分析,完成面向分布式数据的跨系统数据同步中台构建方法设计。实例分析结果表明,相较于MyCAT分表方法,同步中台构建方法在单位时间内跨区域传输的数据文件总量值更大,且碎片信息的出现几率更低,能够更好地贴合稳定跨区域传输数据文件的应用需求,对于“碎片化问题”的解决也有较强地促进作用。In order to prevent the information"fragmentation problem"and realize the stable cross regional transmission of data files,a distributed data oriented cross system data synchronization center construction method is proposed.For the distributed database,determine the specific effect of the data fragmentation principle on the separation of input information,and complete the construction of a distributed data oriented cross system transmission environment.On this basis,establish the synchronization service architecture,determine the key middle office operation mechanism according to the known transmission case relationship,realize the application requirements analysis of the cross system data synchronization center,and complete the design of the construction method of the cross system data synchronization center for distributed data.The example analysis results show that,compared with MyCAT table splitting method,the total amount of data files transmitted across regions in a unit time by the synchronization center construction method is larger,and the occurrence rate of fragment information is lower,which can better meet the application requirements of stable cross region transmission of data files,and also has a strong role in promoting the resolution of the"fragmentation problem".
