Data Marting and BI Development: Part 1

So recently I was asked by my superiors to head the development effort of a dedicated Business Intelligence Portal for our company.  This is to be built leveraging the existing SharePoint 2010 infrastructure we have in place for collaboration.  As I navigate the infant world of data marts, data warehouses, and enterprise class actionable data systems I will be giving my thoughts and musing on the process, the technologies, and the pain points so that hopefully someone out there won't be surprised with them.  Look out for part 2 and my introduction to data marting techniques and concepts!
