摘要
内存数据库是把外存全部或部分数据加载到内存中,在内存中维持数据的主拷贝。与传统的磁盘数据库相比,内存数据库中的所有事务,都是在内存中完成,它不与磁盘进行I/O交互。内存处理速度快,内存数据库适合于对信息及时性要求较高、信息并发量大的系统。基于此,笔者根据内存数据库的特性,设计出一个内存数据库架构并应用在项目中。
Memory database loads all or part of the data of external memory into memory,and maintains the main copy of data in memory.Compared with the traditional disk database,all transactions in the memory database are completed in memory,and it does not interact with the disk for I/O.The memory processing speed is fast,and the memory database is suitable for the system with high demand for information timeliness and large amount of information concurrency.Based on this,according to the characteristics of memory database,the author designs a memory database architecture and applies it in the project.
