摘　　要：为了提升内存数据库从各种故障中恢复的速度,提出了基于影子页面技术、混合日志策略以及模糊检查点思想的内存数据库恢复方法。在分析内存数据库运行过程中主要的时间消耗点的基础上建立了内存数据库的系统模型,通过分析事务过程和检查点过程,讨论了该恢复策略的执行过程以及优点,讲述了内存数据库在此系统模型和恢复策略下的事务故障和系统故障的恢复过程以及系统的性能分析。To improve the recovery speed of main memory database systems from malfunctions, a main memory database recovery method based on shadow paging, hybrid logging and fuzzy checkpointing is presented. Firstly, after analyzing the main points of time consume of the main memory database, a system model of main memory database is constructed. Then the implementation processes and advantages of the recovery method are discussed by analyzing the processing of transactions and checkpointing of the main memory database system. At last, the recovery processes are described under the system model and the recovery method, and the performance of the system is analyzed.
