Are there any good fully-spelled-out examples for Data Warehousing /  
Dimensional modeling in Rails? (An implementation of one of the  
chapters from Ralph Kimball’s excellent "The Data Warehouse Toolkit  
would be ideal…)

I understand Dimensional Modeling. I understand just enough Rails,  
but not quite enough to write the migrations to establish foreign  
keys, one-to-many relationships, etc. It’s a small hurdle, I know,  
but it’s one that I haven’t been able to scale. There must be others  
in the same boat.

(For now, I’m NOT interested in a pre-written package like  
ActiveWarehouse – I’d like to understand what’s going on under the  
hood, at least at first. Later, I will switch over if appropriate…)

TIA.
