A study of concurrency control in real-time, active database systems
Real-Time, Active Database Systems (RTADBSs) have attracted a considerable amount of research attention in the very recent past and a number of important applications have been identified for such systems, such as telecommunications network management, automated air traffic control, automated financial trading, process control and military command, and control systems. In spite of the recognized importance of this area, very little research has been devoted to exploring the dynamics of transaction processing in RTADBSs. Concurrency Control (CC) constitutes an integral part of any transaction processing strategy and, thus, deserves special attention. In this paper, we study CC strategies in RTADBSs and postulate a number of CC algorithms, These algorithms exploit the special needs and features of RTADBSs and are shown to deliver substantially superior performance to conventional real-time CC algorithms.
