Data warehouse architectures rely on extraction, transformation and loading (ETL) processes for the creation of anupdated, consistent and materialized view of a set of data sources. In this paper, we aim to support these processes byproposing a tool for the semi-automatic definition of inter-attribute semantic mappings and transformation functions.The tool is based on semantic analysis of the schemas for the mapping definitions amongst the data sources and thedata warehouse, and on a set of clustering techniques for defining transformation functions homogenizing data comingfrom multiple sources. Our proposal couples and extends the functionalities of two previously developed systems: theMOMIS integration system and the RELEVANT data analysis system.

Abstract

Data warehouse architectures rely on extraction, transformation and loading (ETL) processes for the creation of anupdated, consistent and materialized view of a set of data sources. In this paper, we aim to support these processes byproposing a tool for the semi-automatic definition of inter-attribute semantic mappings and transformation functions.The tool is based on semantic analysis of the schemas for the mapping definitions amongst the data sources and thedata warehouse, and on a set of clustering techniques for defining transformation functions homogenizing data comingfrom multiple sources. Our proposal couples and extends the functionalities of two previously developed systems: theMOMIS integration system and the RELEVANT data analysis system.
