Draw an entity-relationship segment with minimum and maximum cardinalities to represent the relationship between purchase order and purchase based on the following narrative description. Purchases result only from purchase orders. Partial shipments are accepted (e.g. if some of the goods ordered are out of stock and will be shipped as soon as they are in). If goods ordered are unavailable from one vendor, a new purchase order will be placed with a different vendor. If two different purchase orders are placed with the same vendor, that vendor may fill them with a single shipment and invoice.
