The first step is to close your eyes, take a deep breath, and prepare
for a long and exciting journey.

I am _very_ new to the DW/BI scene so bear that in mind when reading
this post.

I have found these websites helpful:

http://www.kimballgroup.com/

However, what works best for me is the old-fashioned approach: book
learning combined with trail-and-error. You might want to stop by a
bookstore (or use Amazon's "Search Inside" feature) and flip through
some of these titles: http://www.kimballgroup.com/html/books.html

I all but stopped buying technical books several years ago because the
information is often outdated by the time the book goes to press.
Having said that, for a subject that is deep, wide, and unfamiliar,
trying to get up to speed using only internet searches can be
frustrating and counterproductive.

Best wishes on your project!
