【摘要】 复制作为一个重要的技术,为分布式数据的存储和处理提供了有力支持。在实际应用中,数据复制已经成为各数据库保障数据安全一致、均衡数据库负载的重要手段之一。在介绍数据库复制技术的基础上,讨论了ORACLE9i的多种复制机制。结合一卡通工程项目开发,系统采用Client/Server结构,在WindowsNT环境下,讨论了基于ORACLE9i的复制技术的具体应用,描述了一个数据库复制技术的实现方案。更多还原

【Abstract】 As an important technique, replication provides powerfulsupport to the storage and process of distributed system. In practice,data replication becomes an important means to ensure unanimity and security of data, and to realize balanced loading of database.Together with the project of "all in one card", a scheme of realizing the database replication based on oracle9i is described, which adoptsclient/server structure under the environment of windows NT.更多还原
