【摘要】 本系统的主要思路是利用Oracle的触发器、Flash Recovery Area等技术,结合J2EE技术,实现一套基于B/S架构的Oracle数据保护和恢复系统,包括权限管理、数据恢复、系统管理三大模块,旨在解决以下问题:(1)建立新的权限控制。Oracle自带的权限控制不够安全,本系统拟创建一套新的权限体系,作为对Oracle的权限的补充,使业务系统的数据使用起来更加安全;(2)建立新的数据恢复。用软件实现Oracle的数据实时恢复,在真正执行危险操作以后,对数据进行针对性地、迅速恢复;(3)实现互触发保护,避免"通过人为的方式直接去drop触发器"之类操作的实现。更多还原

【Abstract】 The system’s main idea is to use the Oracle Flash Recovery triggers,Area technology,combined with the technology of J2EE,realizes a set based on the B/S structure of the Oracle data protection and recovery systems,including rights management,data recovery,system of management of the three modules,aiming to solve the following problems:1,to establish a new access control.Oracle’s own authority control is not safe enough,the system was to create a new set of permissions system,as access to Oracle complement,make business system data is used more safely;2,the establishment of new data recovery.Software implementation of Oracle real time data recovery,in implementation of the real dangerous operations on data,targeted,rapid recovery;3,achieve mutual trigger protection,avoid" through artificial means to go directly to the drop flip-flop" operations to achieve.更多还原
