Data Warehousing and Data Mining

notes international expansion
Based on the success of InSight in the US and Canada, FedEx extended the service to other
countries simply by adding global modules. With geographic validation for every country
on the globe and in-depth support for more than 60 countries in Europe, Asia-Pacific, and
the Americas, the Trillium Software System kept up with FedEx InSight.

14.5 summary

l z We have presented a comprehensive approach how to improve the quality of data
warehouses through the enrichment of metadata based on explicit modeling of the
relationships between enterprise models, source models, and client interest models.
l z Our algorithms, prototypical implementations, and partial validations in a number of
real-world applications demonstrate that an almost seamless handling of conceptual,
logical, and physical perspectives to data warehousing is feasible, considering a broad
range of quality criteria ranging from business-oriented accuracy and actuality to technical
systems performance and scalability.
