摘    要：分析了大型分布式冗余数据库的结构、统计与维护应解决的问题,提出了使用大型分布式冗余数据库的应用系统的结构,通过综合运用触发器、存储过程、运行参数与操作系统的任务计划等技术,能使下级及时自动将数据向上维护并自动取回上级变动数据来维护本地数据库;统计对系统其他功能的影响减至最小,并能使用户根据需求变化配置系统.这种采用运行参数的形式由用户自己配置企业规则等技术思想,增大了系统灵活性,降低了维护的费用.

Abstract: This paper mainly analyzes the structure of the large-scale distributed redundant database,the structure of the application system which is based on this kind of database and the problem in statistics and maintaining the system. The system solves the automatic statistics and maintenance problem utilizing the trigger, storage procedure, run-time parameter and the task plan of the operating system on the whole. The system adopts the technique, which is configured by the users themselves in the form of run-time parameters. This makes the system more flexible and decrease the maintenance cost greatly.
