orders transfer goods internally, some are sales to customers, some are purchases from vendors, and some are returns of goods from customers. The company needs to treat customers, vendors, plants, and storage locations as distinct dimensions that can be involved at both ends of a movement event. For each type of destination or origin, the company wants to know the type of location (i.e., customer, vendor, etc.), name, city, and state. Facts about each movement include dollar volume moved, cost of movement, and revenue collected from the move (if any, and this can be negative for a return). Design a star-type schema to represent this data mart. Hint: After you design a typical star schema, think about how you might simplify the design through the use of generalization. 7th Edition•ISBN: 9780323527361Julie S Snyder, Mariann M Harding2,512 solutions
