Data Warehousing Beyond Tools and Data: Justification, Organization, and Structured Development of Data Warehousing Applications

摘要

Based on a short recapitulation of the Data Warehousing state of the art in large companies, three important non-technical issues of Data Warehousing are discussed. Analyses show that mostly intangible as-stes are being produced, so that justification must concentrate on incremental "quick win" projects and acquisition of sponsors. Organizational roles and responsibilities emerge that are partially contrary to the traditional, transaction oriented organization. Methodological support for some novel systems development tasks is necessary, and some traditional development methods have to be redefined.
