摘要：
Schema mapping is an important approach to solve the problem of data integration. This paper introduces a query discovery algorithm based on schema mapping. By analyzing the mappings and schemas it can automatically construct target query and guarantee that the target result satisfies the target structure and constraints. This allows users to view the other participants' information as an extension of its own information system, without concerning for heterogeneity.
