Data warehouse architecture and quality: Impact and open challenges

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.
