CM wants to make data more available to their marketing analysts so that they can develop more effective marketing programs. They want to accomplish this goal without slowing down the performance of their existing OLTP system. They have decided to create a Data Warehouse to provide the information that the marketing analysts need. Your task is to design the database for the Data Warehouse.
The marketing analysts have asked for the ability to see sales data by product (inventory), consumer, employee who placed the order, and by various date variables including date, week, quarter, year, day of the week, and season. They do not need to see every sale but would need to see product sales summarized for each product on a daily basis.
