A data transformation method based on schema mapping

You Li , Dongbo Liu and Wwiming Zhang

Abstract


Schema mapping is an important approach to solve the problem of data integration. This paper introduces a research prototype called SDE, which is a system for managing and facilitating the complex tasks of heterogeneous data transformation and integration. We also present a data transformation method based on schema mapping techniques. By analyzing the mappings and schemas it can automatically fulfill the task of data transformation and guarantee that the target result satisfies the target structure and constraints. It allows users to view the other participants' information as an extension of its own information system, without concerning for heterogeneity.
