Automatic approach for generating ETL operators (1212.6051v1)

Abstract: This article addresses the generation of the ETL operators(Extract-Transform-Load) for supplying a Data Warehouse from a relational data source. As a first step, we add new rules to those proposed by the authors of [1], these rules deal with the combination of ETL operators. In a second step, we propose an automatic approach based on model transformations to generate the ETL operations needed for loading a data warehouse. This approach offers the possibility to set some designer requirements for loading.
