【摘要】 <正>传统数据库恢复本身就是一个复杂的问题,而实时数据库(Real-time Database,RTDB)的恢复由于其数据和事务的定时约束显得更为复杂。这是因为:第一,除需恢复其内部一致性外,实时数据库还需恢复其时间一致性及还原已改变物理世界的外部状态。第二,不同于传统数据库(数据总是永久的、一更多还原

【Abstract】 Recovery processing is vital for guaranteeing the consistency of databases in the presence of failures. The recovery schemes of traditional databases are not suitable to recover real-time databases due to time consistency and real-time requirements such as timing,preemption and predictability.It is necessary to study advance recovery schemes meeting these requirements.In this paper,previous approaches recovering real-time databases are surveyed and classified,and further researches on the recovery of real-time databases are pointed.更多还原
