Abstract
Real-Time Database Systems (RTDBSs)must meet time constraints in addition to the integrity constraints present in most other database systems. From the late 1980s a significant amount of research work has been performed on the design and performance evaluation of Concurrency Control Mechanisms (CCMs) for RTDBSs [5, 4,7, 8, 11]. Given the spate of papers on (firm) real-time CCMs of the late 80s and early 90s, there appears to have been a reduction in the number of papers in recent years. More recent works (e.g., [6]) study non-traditional real-time scenarios. We have not been able to discover papers reporting significant performance gains from CC strategies designed for traditional firm RTDBS in the past few years. One plausible explanation is that performance gains are harder to achieve. One way in which higher performances can potentially be reached is by utilizing priority information in conflict-resolution. Indeed, the authors of [5] ask the question “How can the priorities be used to improve the performance of the optimistic algorithm?”.
