分布式工程数据库系统中事务提交机制的研究
Research on the Transaction Commit Mechanism for Distributed Engineering Database System

摘要: 分布式工程数据库事务的特性不同于常规的分布式事务，基本的两阶段提交（B2PC）协议已不适用.文中建立了基于嵌套结构的分布式工程数据库事务管理子系统的体系结构，并提出了适用于分布式工程数据库的事务两阶段提交协议，包括该协议的原理、算法以及对故障的处理方法，能够较好地支持分布式工程设计过程的进行.Abstract: Since the ACID properties of transaction in distributed engineering database differ from that in conventional one, the Basic Two-Phases Commit (B2PC) protocol no longer fits it. Based on the nested model we established a structure for transaction management in a distributed engineering database. We also proposed a new Two-Phases Commit protocol with detailed description of its principle， algorithms and ways to handling failures.
