摘要
基于多数据库面向用户交互操作的特点，分析了ＣＳＣＷ环境下多数据库的多态性、自治性及分布性，提出了ＣＳＣＷ环境下对多个数据库的操作模型，以及用户对多数据库操作的语句模型及其实现策略，并进行了计算机模拟实现．结果表明，ＣＳＣＷ环境下对多个数据库的操作语言模型具有较好的性能．
Based on the characteristic of oriented user's interactive operations of multidatabase, the paper analyzed the heterogeneity, autonomy and distribution of multidatabase under CSCW environment. The operation model on multidatabase in CSCW environment was put forward,and a kind of operating language model for interoperability in multidatabase system and its implemental schema were proposed. The computer simulation implementation was carried out,which shows that the operation language model on multidatabase in CSCW environment has better performances.
