A Survey on Admission Control Paradigm for Real-Time Database

Transactions travel in a RTDB system through various components until their termination. Our objective is to design an experimental real-time database system which would be suitable enough to study the most important real-time database issues, including CPU scheduling, concurrency control and conflict resolution. Because of the strong interactions among the processed components, proposed system can help us to understand their effect on system performance and to identify the most important factors. A transaction is considered to have finished executing if exactly one of two things occurs: Either its primary task is completed (successful commitment), or its recovery block is completed (safe termination). Committed transactions bring a profit to the system, whereas a terminated transaction brings no profit. The goal of the admission control and scheduling protocols (e.g., concurrency control, I/O scheduling, memory management) employed in the system is to maximize system profit. We describe a number of admission control strategies and contrast (through simulations) their relative performance.
