Data Warehouse question

Hi,

 What is the better way :

  1. To keep a "fact" table and a number of "dimension" tables separate ( perform a star join for each query ), or
  2. Denormalize the tables and avoid the joins.

  Fact table - 3M - 4M rows.
  Dimension tables - 20 - 30K rows max.

 Thanx. Michael.
