A schema integration architecture for multidatabase systems
Guoren Wang, Ge Yu, Bin Zhang, Huaiyuan Zheng · 2002
The paper presents a three level schema integration architecture which consists of local schemas, mapped schemas, and a global schema for global multidatabase systems. Schema mapping rules, merging and restructuring rules are also presented for mapping local schemas into mapped schemas and for merging and restructuring the mapped schemas to get a final global schema.
