Ross,
A DW is defined by purpose and design, not by size.
A collection of Data Marts, ( tables for star joins ) is not
a DW either. DW's are used to create data marts.
If you don't already have the database books from
Kimball, I suggest you acquire them.

Data Warehouse Lifecycle Toolkit
http://www.amazon.com/exec/obidos/ASIN/0471255475/ref=pd_sim_books/104-7669992-7054323
These are must haves for understanding and designing DW.
