【摘要】 论文以母子公司型医院集团[1]为代表,介绍了运用ORACLE高级复制技术实现集团化医院数据交换的方案。文中提出基于增量数据的异步复制方案是现实可行的,尤其是多级物化视图[2]的引入,增强了该方案的灵活性。此外,论文还讨论本方案引发的数据冲突问题,提出对主体表的分片复制可以更大可能的避免数据冲突。更多还原

【Abstract】 In this paper, we introduce a solution applying oracle advanced repli cation to the implement of hospitals’ data exchange on the background of star-mo del hospital group. The solution based on asynchronous replication about data in crement is feasible. Especially, the application of multitier materialized views is useful. In addition, the data conflict is discussed in detail, We propose a fragmentation measure to avoid data conflicts.更多还原
