摘要： 提出一种新的适用于嵌入实时数据库系统(ERTDBS)的并发控制协议VB-SCC,该协议将事务的价值函数和SCC协议相结合。其目标是提高并发事务带给系统的价值收益。另外,该协议建立在基于功能替代的实时事务模型上,适用于嵌入式实时数据库系统。最后通过模拟试验证实VB-SCC比现有的VOSP、VPSP协议具有更好的稳定性。

Abstract: This paper presents a new concurrency control protocol VB-SCC in real-time embedded database.The main idea of VB-SCC is try to improve the total value of concurrency transactions in embedded database.VB-SCC associates with the real-time transaction model based on function alternative.At last,the performance is compared with VOSP,VPSP through a simulation system.It proves that VB-SCC protocol has better stability than VOSP & VPSP protocols.
