Towards data warehouse quality through integrated requirements analysis

Few researches have been carried out to provide means of requirements analysis in the novel field of data warehousing. This paper proposes a methodology for requirements analysis in the context of data warehouse systems denoted by: integrated requirement analysis for designing data warehouse (IRADAH), as a way to accomplish the peculiar aspects inherent to such systems. Focus of this paper is quality integration (business quality, technical quality, and information quality) into the requirements analysis to reduce the risk of failure in data warehouse project. The paper aims to tackle four research questions: how to integrate the four existing approaches to warehouse design; how to identify warehouse elements from operational data sources; how to embody corporate strategy and business objectives; and how to translate user requirements into appropriate design elements.
