| 摘 要： | 并发控制是改善数据库系统事务性能的最重要机制，也是Native XML数据库研究领域的一个难点。通过简化XPath数据模型，定义基于该模型的几种Native XML数据库操作，提出一种新的基于XPath的加锁协议，分析该协议下的调度是可串行化调度，并针对其性能问题进行探讨。

| Abstract: | Concurrency control is the most important mechanism of improving the transaction capability of database system.And it is also a difficulty in the field of Native XML database.Some kinds of Native XML database operations based on the simplified Xpath data model are proposed.On the basis of this,an Xpath-based locking protocol is put forward and the schedule within the locking protocol mentioned above is proved to be serializability.Some detailed discussion is given to analyze the capability of concurrency fo... |
