摘　　要：提出了多版本乐观并发控制协议(MVOCC),缩短了只读事务的响应时间,减少了通信开销,避免了不必要的事务重启动。实验结果表明该协议优于OCC协议和TO协议。Multiple version optimistic concurrency control protocol (MVOCC) is presented. The protocol can eliminate conflicts between read-only and update transactions and resolve data conflicts flexibly using dynamic adjustment of serialization order to avoid unnecessary transactions restarts. The results of experiment show that the protocol performs better than optimistic concurrency control protocol (OCC) and timestamp order protocol (TO).
