摘要 本文在分析联邦数据库系统成员异构的特点后,论述了一种基于输入/输出模式和概念模式的转换方法,通过该转换处理可以有效地解决模式异构的问题。这种方法已在SU-FDBS原型中实现。 After analysing the features of heterogeneity for a federated database system, this paper presents a mapping approach based on inport/export schema and conceptual schema, through which schema incompatibility problems can be solved effectively. Now the mapping approach has been used to develop a federated database system SU-FDBS.
