摘　　要：在系统集成环境中,各异构系统之间数据同步交互频繁且数据量大的背景下,针对如何在多源异构系统之间实现增量同步的问题,提出通过设计一种结合数据库日志分析与Web Service技术来实现。重点研究如何在面向对象Caché数据库大日志文件中下载相应日志,结合Caché数据库与正则表达式解析日志,捕获变化数据。选用Ensemble平台集成各异构系统,使用Web Service+XML的方式推送增量数据到各目标系统,实现主库到各异构分库同步增量数据的目的。该方法应用到某医疗环境的信息系统中,实现了多源异构系统的增量同步,在增量数据不含大对象情况下,增量同步获得较好效果。Under the background of system integration environment,the data synchronization between heterogeneous systems is frequent and the amount of data is huge. This paper designed a combination of database log analysis and Web Service technology to solve the problem of how to achieve incremental data synchronization in multi-source heterogeneous systems. This paper focused on the issues of how to download the corresponding log from the large log file of the object oriented Caché database, and analyzed log to capture the changes data combining Caché database and regular expression. Using the Ensemble platform to integrate heterogeneous systems,it push the incremental data to each target system using Web Service ＋ XML,and realized the purpose of the incremental data synchronization from the main system to all subsystem. The proposed solution was applied to the information system of a medical environment. The results show that this solution realizes the incremental synchronization of multi-source heterogeneous systems. The incremental synchronization achieves better results,and the experiment obtains a better effect of incremental synchronization under the condition of excluding large objects.
