摘要： 本文首先简述了三个较典型的DDBMS(Distributed DataBase Management System)-SDD-1、SIRIUS-DELTA和POLYPHEME主要侧重于系统开发现状、体系结构及主要技术;并在附表中列出较有影响的十多个DDBMS系统。最后通过实例较客观地分析了该领域所面临的主要问题:系统构成方式、数据模式及分布、并发控制等技术。其目的在于:通过扼要介绍三个典型系统及附表中给出的技术特性,可以全面了解当前DDBMS的发展水平及其设计、实现DDBMS方法,另外,通过分析讨论其典型技术之利弊,把握住DDBMS的现状与发展方向。

Abstract: Three typical distributed database management systems (DDBMSs), SDD-1、 SIRI-US-DELTA、and POLYPHEME, are briefly analysed with emphasis on their developing state, architecture and primary technical properties Some fundamental problems in the area of DDBMS、 such as method of construction, concurrence control、 and data model and data distribution, are discussed. The main characteristics of more than ten DDBMSs that have Played a more or less important role in the development of DDBMS are listed in the appendix.
