Do you think a data warehouse is appropriate for DSI? Why or why not? Figure 8-9 implies that data marts require the existence of a data warehouse, but this is not always the case. DSI could construct a data mart containing in-bound logistic and manufacturing data without a data warehouse. In this case, the data mart would need to clean and prep its own operational data. Given DSI’s product and the nature of its 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 DSI’s competitive strategy.
