Abstract

Many modern organizations operate in a dynamic and large-scaled web-based environment that involves critical and frequent interactions with external organizations. Within this context, the associated data warehousing environment is often dynamic and evolutionary, with sometimes frequent changes in the quality of various resources (e.g. source systems, processes, metadata), and also in the users' quality requirements. There is thus the need to not only capture quality changes on-the-fly, but also provide automated quality notifications to relevant end users. Managing data warehousing systems in such environment imposes many new challenges for DW design, management and maintenance. In this paper, we propose an extended data warehousing systems architecture that incorporates and extends the concepts of the Quality Factory (QF) and the Quality Notification Service (QNS) that were previously presented in the Cooperative Information Systems (CIS) literature.
