Hello,
I'm hoping someone might be able to point me in a direction, even if its pointing me to a different forum.
What i'm looking for is how to get started with learning how to set up a data warehouse. We are looking at maybe purchasing a report system but first we would need to cleanse and structure our database.
I know this is kind of a big pond and i'm just looking for a place to start. I'm not huge on books so if there is a class i should look at taking or website,forums, whatever works.
Thanks in advance.

Data Warehousing requires a slightly different set of skills than regular OLTP do.
First, a deep understanding of the purpose of the DWH is needed.
Second, a decision has to be made in regards of how it will be modeled - in simple terms data modeling could either be relational (Inmon) or dimensional (Kimball).
In terms of available resources in the market, I think most people would agree if I say that most DWH trained DBAs, ETL specialist and Reporting specialist are trained on the Dimensional model.
Once you decide which way to go, I would suggest to start small, build your DWH one Datamart at a time - start with the simplest data domain you can find then build a Datamart that describes it and in the process start building the shared infrastructure of your DWH.
In my opinion, if an organization is serious about DWH and there are not properly trained/experienced internal resources then it should get help from experienced people so to ensure success.

Reading Kimball's book on Data Warehousing isn't a bad place to start. It's a great introduction to the concepts in DW design and modeling. But it's definitely true that you need to know what you're doing before doing that. And definitely start small.
