摘要
由于实时数据库应用的特性是满足事务的时限,在多数情况下,可串行化协议不适合实时数据库系统,必须放松标准。本文提出基于相似性的高优先级两段锁协议(H2PL)算法,在系统可以忍受的不一致性范围内,系统的性能提高了。
As real-time database system should meet transaction's deadline as most as possible,the serializability concurrency protocol is not suit to real-time database system at most case.It must be relaxed.The paper proposes an algorithm based on H2PL with comparability.With the strategy,systematic performance is enhanced in a scope of no-consistency.
