7. Explain why a data warehouse is inappropriate for Majestic. Figure 9-7 implies that data marts require the existence of a data warehouse, but this is not always true. Majestic could construct a data mart containing customer, equipment, and food expense without a data warehouse. In this case, the data mart would need to clean and prep its own operational data. Given the nature of Majestic’s business, what value might such a data mart provide? List seven decisions that such a data mart might support.

Describe the BI system that would support each decision. Explain how such BI systems contribute to Majestic’s competitive strategy.
