| 摘 要： | 介绍了几种用于RTDBS(实时数据库系统)中的并发控制模型以及它们在分布式环境下(DRTDBS)的拓展。根据DHP-2PL提出一种改进的并发控制模型。在该模型中，引入优先级分配机制和加锁检测机制。通过这两种机制可更好地协调DRTDBS中一致性与截止期的关系，同时也解决了DHP-2PL中事务高重启率的问题。 |

| Abstract: | Some concurrency control models used for RTDBS were introduced, and how to use them on the distributed environment (DRTDBS) was discussed. At the same time an improved concurrency control model based on DHP-2PL was presented. At this model, priority allocation scheme and locking checking scheme were added to DHP-2PL. By these schemes, the problems between consistence and deadlines could be deal with harmoniously. And the high ratio of transactions restart in DHP-2PL was also decreased. |
