Many thanks to those of you who have sent feedback, praise, comments and questions. It is good to know that the book has been well received, and is being studied carefully. Happily, I have only been made aware of a couple of errors. Here they are, in page number order.
- Page 25: Third paragraph, last sentence, "...has summarized order_facts by completely omitting the salesperson and order_type dimension tables." This sentence should end "customer and order_type dimension tables," in accordance with Figure 1.8.
- Page 171: Figure 5.7 incorrectly lists a BRAND_KEY in the upper right of the diagram. The column should be labeled PRODUCT_KEY, as described in the text.
- Page 195: Step 2.1.4 in figure 6.3 should have a connection to step 2.1.5 (as indicated in the text on page 203).
