协同数据库中异构数据的集成技术

Heterogeneous Data Integration Technology for Cooperative Database

探讨分析协同环境下各协作方交互过程中存在的数据异构问题,针对协同数据库的特点及设计方法,提出一种计算机支持的协同工作(Computer Supported Cooperative Work,CSCW)环境下异构数据的集成结构模型,并对模块查询过程的算法进行描述,阐述可扩展标记语言(Extensible Markup Language,XML)文档与数据库数据的映射这一异构数据集成的关键技术,解决协同数据库环境下信息的共享问题。

The problems of heterogeneous data which exist in the interactive process of all collaborations under the coordinative environment are analyzed. Aiming at the characteristics and design method of cooperative database, a heterogeneous data integration model in CSCW environment is proposed and the algorithm of module query process is described. The key technologies in the process of heterogeneous data integration that is the mapping between XML documents and databases are described. All of these efforts can efficiently solve the information sharing problems in cooperative database environment.
