摘要：A real-time database system (RTDBS) is a database system providing all features on traditional databasesystem such as data independence and concurrency control, while at the same time enforces real-time constraints thatapplications may have. Like a traditional database system, a RTDBS functions as a repository of data, providesefficient storage, and performs retrieval and manipulation of information. However, as a part of a real-time system,tasks have time constraints; a RTDBS has the added requirement to ensure some degree of confidence in meeting thesystem’s timing requirements. A real-time database is a database in which transactions have deadlines or timingconstraints. Real-time databases are commonly used in real-time computing applications that require timely access todata. And, usually, the definition of timeliness is not quantified; for some applications it is milliseconds, and for othersit is minutes. In this paper we have discussed the issues related with timing constraint for distributed real timeapplication.
