6. Choose a single universal currency (dollars, pounds, euros, etc.) and store both the local value of a financial transaction together with the universal currency value in every low-level financial transaction record.
7. Don't translate dimensions in your data warehouse. Settle on a single, master language for dimensional content to drive querying, reporting and sorting. Translate final rendered reports, if desired, in place. For hand-held device reporting, be aware that most non-English translations result in longer text than English.

For more information, please consult these additional references, which detail the approaches I use for addressing international data quality. The best reference for understanding international data representation issues is Merriam-Webster's Guide to International Business Communications, Second Edition, by Toby Atkinson. I have written two relevant white papers: Architecture for Data Quality in an Enterprise DW/BI System and Architecture for Integration in an Enterprise DW/BI System. These white papers are sponsored by Informatica but are free from vendor product recommendations.
