摘要
该文提出一种适用于实时数据库的新可推测并发控制(New Speculative Concurrency Control,NSCC)协议。该协议在传统的SCC协议基础之上,进行一系列改进,避免了大量不必要的事务重启,提高了并发度。最后,通过Petri网理论验证其可行性和正确性。
A new Speculative Concurrency Control Protocol（NSCC） for real-time database is proposed.The protocol is based on the traditional SCC.Mang restartings are advoided,and the concurrency of transaction is enhanced.Finally,using theory of Petri net,it proves that the protocol is feasible and effective.
