摘　　要：为提高和优化测控信息数据库实时性能,设计了一种基于内存数据库与关系数据库的两级实时存储模型,文章详细阐述了两级数据库的存储机制及其生命周期,分析归纳了实时测控信息的特征及存储策略,提出了内存数据库基于"T树"+"哈希"索引相结合的自适应索引算法和两级数据库实时数据同步机制等关键技术,从而提升和优化了数据库的实时性、可靠性和安全性,为今后实时的扩展应用提供了可靠数据保证.In order to make up the real-time performance of tracking and control information database, this paper design a kind of two-layer＇s real-time data storage model based on memory database and relational database. In this article, the two-layer＇s real-time data storage mechanism and life cycle are expounded in detail, analyzing and inducing the real-time data characteristic and storage strategy, providing the memory database＇s self-adaption index algorithm of T-tree index and hash index, and introducing the database synchronization mechanism between the memory database and relational database and so on. In this way, so as to improve and optimize the real-time, reliability and security of database, for future expansion of the real-time application data provides a reliable guarantee.
