Real-Time Concurrency Control Protocol Based on Accessing Temporal Data
基于数据时态特性的实时事务并发控制

After analyzing the temporal data characteristics and the effects on scheduling transaction, a real-time concurrency control protocol is proposed, which improves the performance of real-time systems by evaluating data-deadline and transactions execution time, improving transactions validation rules, and adjusting transactions committing order. Theoretical analysis and experimental results demonstrate that the new protocol reduces the transaction restarts numbers and the miss deadline percentage, and outperforms the previous ones.
