| 摘 要： | 原生XML数据库(NXD)的事务处理机制是保障数据库正常运行的核心机制,是当前研究的一个重点.在分析了现事务处理机制的基础上,结合关系数据库中成熟的封锁理论,提出基于XPath的XPL四种锁封锁机制,对数据库的操作和事务做出了明确的定义,并给出了实例进行验证说明.

| Abstract: | Transaction processing mechanism of NXD database is the core mechanism to ensure database to run steadily,that is high light of research currently.This paper analyzed the current transaction mechanism,together with approved locking rules of relational database,proposeed XPL four-lock protocols based on XPath.It also gave the clear definitioin to database operation and transaction,test and expound with practical cases offered inside. |
