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.
