Prоvide а Sequence Diаgrаm that represents the sequence оf messages between dоmain objects that would be shared to allow one customer to place an order (composed of package(s) and a delivery location) and have that order fulfilled by a drone operator. The entities referenced in this diagram must be consistent with the entities you generated in your Domain Model and Use Case above. We will accept a hand-drawn diagram, or the text-based alternative and we won't "favor" either format - choose what works best for you. All hand-drawn diagrams should include the following elements as needed: Domain objects with unique names for multiple objects of the same class Vertical lines to represent the object creation and lifecycle duration Named message between objects that include appropriate parameters (solid lines and directional arrows) Labeled return values between objects where required (dotted lines and directional arrows) Selection constructs with the appropriate boolean conditions to determine which alternatives should be selected Iteration constructs with the appropriate boolean conditions to determine when the loops should be terminated Note that not all of the provided domain object columns must be used. You're also welcome to provide a text-based description of your sequence diagram instead of the hand-drawn version. Your description must be precise, and you must label these aspects of the diagram clearly: All domain objects (with unique name if required) : object class name All messages along with the sending and receiving object names, and the parameters (if required) All return value communications All selection and iteration constructs, clearly labeled using indentation or "paragraph-style headers" And (most critically) all messages must be shown in the proper sequence For this example sequence diagram, your expected text-based submission would be: Messages: :classX --> message2() --> objA:classY objA:classY --> return ref_a --> :classX :classX --> message2() --> objB:classY objB:classY --> return ref_b --> :classX begin loop for each of the collected references >> :classX --> message3(single_ref) --> :classZ end loop :classZ --> message5(winner) --> :classX
