Performance Evaluation of Adaptive Disk Scheduler for Real Time Database System
The design and implementation of real-time database presents many new challenging problems. Compared with conventional database, real-time database have distinct features: they must maintain the coherent data while satisfy the timing constraints associated with transaction. With evolution of Earliest Deadline First (EDF) by the researchers, laid the path for development of RTDB, it is very inefficient in overloaded workload conditions. Adaptive Earliest Deadline (AED) improves the performance which uses feedback control mechanism to detect overloaded condition and tries to attain HIT ratio 1.0.
