Banking Data Warehouse

Václav Kmoch · Digital Repository (National Repository of Grey Literature) · 2008

Předmětem řešení je porovnání dvou základních metodologií pro návrh a tvorbu datových skladů. Jedná se o multidimenzionální metodologii podle Dr. Ralpha Kimballa (Kimball?s methodology) a metodologii informačně technologického prostředí podle Billa Inmona (Inmon?s methodology). Úvodní část práce je zaměřena na teoretický rámec oblasti datových skladů. Důraz je zejména kladen na objasnění pojmosloví a základních datových vztahů. Praktická část seznamuje s konkrétní architekturou obou přístupů a podává ucelené porovnání zmíněných metodologických přístupů. Cílem práce je poskytnutí nadhledu nad aplikací obou metodologií dle vybraných kritérií praktického použití, která zastupují objektivní hlediska vývoje a správy prostředí datového skladu. Přínosem práce je konkrétní komparace nejpoužívanějších architektur v prostředí datových skladů bankovních institucí, ze kterého vychází praktická zkušenost autora.

Data Warehouse Testing

Matteo Golfarelli, Stefano Rizzi · International Journal of Data Warehousing and Mining · 2011

Testing is an essential part of the design life-cycle of a software product. Although most phases of data warehouse design have received considerable attention in the literature, not much research has been conducted concerning data warehouse testing. In this paper, the authors introduce a number of data mart-specific testing activities, classify them in terms of what is tested and how it is tested, and show how they can be framed within a reference design method to devise a comprehensive and scalable approach. Finally, the authors discuss some practical evidences emerging from a real case study.
