Abstract: This paper introduces the designing method of the distributed database based on Oracle, besides the long-distance accessing technology of Oracle database and the mechanism of distributed transaction are discussed deeply, expatiates the realizing process of distributed database technique in large appliance enterprise’s employee wage-system construction design and businesses handle with search. By introducing the distributed technology, it puts the databases on different points as a logical whole, data consistency, integrity and safety all can be realized, which will increase the governing efficiency of the information, and designs a safe, reliable, efficient distributed database application system according to its actual requirement.

Key words: Distributed database, Oracle, Database links, Distributed transaction

摘要： 介绍了基于Oracle的分布式数据库设计方法，并对Oracle数据库远程访问技术及其分布式事务实现机制进行了深入探讨，阐述了分布式数据库技术在大型家电企业商流直销员工资系统结构设计及事务处理和查询中的实现过程。.通过引入分布式技术，将多个站点上的数据库作为一个逻辑上的整体，数据一致性、完整性及安全性都得以实现，使信息资料的管理效率得以提高，并按实际需求设计一个安全、可靠、高效的分布式数据库应用系统。
