Consider the following six relations for an order-processing database application in a company: CUSTOMER (Cust\#, Cname, City) ORDER (Order\#, Odate, Cust\#, Ord_Amt) ORDER_ITEM (Order\#, Item\#, Qty) ITEM (Item\#, Unit price) SHIPMENT (Order\#, Warehouse\#, Ship_date) WAREHOUSE (Warehouse\#, City) Here, Ord_Amt refers to total dollar amount of an order; Odate is the date the order was placed; Ship_date is the date an order (or part of an order) is shipped from the warehouse. Assume that an order can be shipped from several warehouses. Specify the foreign keys for this schema. (FORMAT: the table name, its foreign key(s) name, and the table and column names the foreign key references for each of the foreign key, if any.) You can use the same format as the code contained in the table creation command to construct your answer. Example is as follows: Sample answer: Table_name_1 constraint_name (column_name_1) references table_name_2 (column_name_2)
