| 摘 要： | 针对分布式并行数据库系统DPDBS中数据库副本数、数据库分布等信息的动态性，提出全局数据目录的动态管理和维护算法。该算法将数据目录一致性检查嵌入数据库执行过程中，通过改进两阶段提交协议和采用捎带、恢复和并行处理等技术，在低开销的情况下动态地保证了全局数据信息的一致性和实时性。

| Abstract: | Aiming at the dynamic characteristic of the data directory in distributed and parallel database system(DPDBS),the dynamic arithmetic for whole data directory is put forward.The arithmetic is implemented by embedding the consistency check of whole data directory in the course of database executing,improving the two phase commit protocol,and making use of technology such as recovery,parallel handling,and other technology.The application proves its efficiency. |

| Keywords: | Distributed and parallel database system Whole data directory Two phase commit protocols(2PC) Consistency |
