7. Strauble-Dytisa is an OEM manufacturer of refrigerator parts (doors, motors etc.) in Quaretero, Mexico, that supplies parts to manufacturers in the U.S. Orders for parts are received from the manufacturers (“mfr”). Each order has an “ord#” (order#), “ord_dt” (order date), “del_dt” (delivery date) and a number of “p#’s” (part#’s) “p_name” (part names) and “qty” (order quantities). An order could include for e.g. #5532 “door handles” qty 100; #3103 “hinges” qty 600…. Since different manufacturers can order the same part (e.g. hinge), the order “qtys” from different orders are combined into one ”#needed” for each part. As soon as an order is received, it is examined by engineering (do not model this) to see if they have the die (a tool used to make the parts, one die is needed for each part) in stock or not. Dies, designated by the Die# are stored in a shelf designated by a shelf#. New dies are manufactured as needed by engineering students in a nearby workshop (do not model this). The parts are then manufactured using the dies which are inserted into hydraulic presses and “stamped” (do not model “presses” and “stamping”). As parts are manufactured, the company places the finished parts in a container (designated by the C#), and updates a tag on the container. The tag has the “C# “, the # finished, the #needed. Each type of part is placed in a separate container (e.g. all door panels in one container, backplanes in another etc.). When the required # of parts are manufactured, the tags are removed and the parts are shipped out (do not model this). List the eclasses and draw an ER diagram for this situation.





and the owning continued with a functional dependency diagram.....


8. Develop a functional dependency diagram for the situation above.

Even though its too late I figured I'd let you know that most people here on MG will not do homework. We can tell when the person truly needs help and when they are just being lazy. Don't mean to sound harsh.
