timing constraint

Abstract : the theory and technology of database is developing very rapidly , in today ' s information society , it ' s omnipresent , but the application of database is extending from traditional fields to new fields , especially , in process control field , the application is very different to traditional application , their facility and character , both database and real - time handling must be different , it not only need database to support sharing of large data for maintaining accordance but also need real - time handling to support it ' s transactions and data ' s timer bound . so real - time database technology now become a spickandspan direction , through rtdb we can well bring data management , data exchange and data sharing of process control supervise system into effect
数据库理论与技术的发展极其迅速，其应用日益广泛，在当今的信息社会中，它几乎无所不在，但数据库的应用正从传统领域向新的领域扩展，尤其在过程控制领域，有着与传统应用不同的特征，这种应用对数据库和实时处理两者的功能及特性均有需求，既需要数据库来支持大量数据的共享，维护其数据的一致性，又需要实时处理来支持其任务(事务)与数据的定时限制。实时数据库技术成为数据库技术发展的一个崭新方向，通过实时数据库系统能够很好的实现对过程控制监控系统中的数据管理、交换和共享。
