Data Warehouse Architecture and Quality: Impact and Open Challenges

Year 2013
PDF URL view

The CAiSE 98 paper “Architecture and Quality in Data Warehouses” and its expanded journal version [17] was the first to add a Zachman-like [35] explicit conceptual enterprise modeling perspective to the architecture of data warehouses. Until then, data warehouses were just seen as collections of – typically multidimensional and historized – materialized views on relational tables, without consideration of modeling of the (business) concepts underlying their structure. The paper pointed out that this additional conceptual perspective was not just necessary for a truly semantic data integration but also a prerequisite for bringing the then very active data warehouse movement together with another topic of quickly growing importance, that of data quality.
