Now presume that your company$$s Chief Information Officer $($CIO$)$ is a strong believer in smaller$-$scale efforts rather than large, enterprise$-$intensive ones such as CIF or the Dimensional Data Warehouse Bus Architecture. The CIO directs you to define the architecture for a Front End Data Mart approach, with the front$-$end marts set up by region. $($Another helpful hint: make sure you fully understand what the "front end data mart" architecture means and what one looks like...all of it$,$ the entire end$-$to$-$end architecture!$)$
