JaybeeSQL,

As Eric said familiarize yourself with what a true data warehouse is. The Kimball Dimensional Model to data warehousing is the standard (they've been doing it for 30+ years). I have that book and it's a great read (well written and easy to understand). Dimensional modelling is fairly different than typical normalized databases and if built right will be a great foundation for analytics. ETL, SSAS, BI etc. are all separate parts to the analytics machine but dimensional modeling is how we organize, store and maintain the business processes that users will measure. 

If you start building ETL packages then I'd suggest one of Wrox publishing's "Integration Services" books.  I have the 2008 version and use it for SQL 2014 but they have newer ones like this 2014 version: Wrox 2014 Integration Services
