Abstract

Transactions processed in a real-time database system (RTDBS) are associated with real-time constraints typically in the form of deadlines. Computer-integrated manufacturing, the stock market, banking, and command and control systems are several examples of RTDBS applications where the timeliness of transaction response is as important as the consistency of data. Design of a RTDBS requires the integration of concepts from both real-time systems and database systems to handle the timing and consistency requirements together; i.e., to execute transactions so as to both meet the deadlines and maintain the database consistency.
