Many current approaches for constructing data warehouses rely on graph based visual languages to simplify the ETL programming task. In this paper we propose a new visual language for ETL production, which enhances graph based languages with the spreadsheet metaphor. The latter naturally lends itself to the data manipulation and data transformation task, giving immediate feedbacks on the effects of the planned data transformation processes. We also provide a grammar for the proposed language.

Abstract
Many current approaches for constructing data warehouses rely on graph based visual languages to simplify the ETL programming task. In this paper we propose a new visual language for ETL production, which enhances graph based languages with the spreadsheet metaphor. The latter naturally lends itself to the data manipulation and data transformation task, giving immediate feedbacks on the effects of the planned data transformation processes. We also provide a grammar for the proposed language.File in questo prodotto:
