摘　　要：针对目前Native XML数据库中事务处理机制的不足,介绍了一种新的事务处理系统OBSA-TPS,实现了一种基于语义路径的多粒度封锁机制(Schem a Path Lock),提高了非结构化信息存储系统事务处理的并发能力,避免了在Native XML数据库中使用常规方法时产生的幻像问题。The distributed transaction process model of relational database is insufficient for the native XML database management system （NXD）. A novel transaction processing model named OBSA-TPS is introduced in this paper to overcome the problem. It implements a new granularity lock model named Schema Path Lock, which is based on the DTD/Schema of XML documents and the uniform semantic environment supplied by OBSA system, improves the ability of parallel transaction processing.
