摘要
实时数据库是实时系统中极其重要的一个系统软件 ,时间相关特性决定了系统能否满足实时应用需求 文中通过对实时数据库时序一致性的讨论 ,说明了实时数据库绝对时序一致性和相对时序一致性的概念和定义 并提出了在实时数据库系统开发中用优先级解决绝对时序一致性和用数据视图解决相对时序一致性的方法 通过解决系统的时序一致性 。
Real-time database management system is an important system software of the real time application system, the time character is related with the application desire. The paper discusses the time sequence consistency in real time database and introduces the concept of absolute time sequence consistency and relative time sequence consistency. This paper suggests that in real time database,priority levels be used to slove the problem of absolute time sequence consistency and data view be used to solve the problem of relative time sequence consistency.Real time data consistency in practical application is guaranteed by solving time sequence consistency in real-time database management system.
