摘　　要：传统的磁盘数据库因为要进行大量的I/O操作,不能很好地满足系统的实时性要求。内存数据库系统将用户数据加载到内存中,使得数据的处理速度大大提高,可满足各种实时应用系统的实时数据处理需求。本文介绍了消防监控系统中内存数据库索引的设计方法,并对比了两种方法下的系统运行效率。Since the traditional disk resident database needs to carry out a large number of I/O operations, the system can not adequately satisfy the real -time requirements. However,main memory database system keep the data of user stored in memory, so that the speed of data processing is greatly improved, which can meet a variety of real - time data processing needs of real - time application system. This paper has introduced the design methodology of main memory, database index in fire monitoring system, and compared the system running efficiency in these two situations.
