In this paper we propose a system supporting the semi-automatic definition of inter-attribute mappings and transformation functions used as ETL tool in a data warehouse project. The tool supports both schema level analysis, exploited for the mapping definitions amongst the data sources and the data warehouse, and instance level operations, exploited for defining transformationfunctions that integrate in a common representation data coming from multiple sources.Our proposal couples and extends the functionalities of two previously developed systems: the MOMIS integration system and the RELEVANT data analysis system
